ive just swapped my rotors and pads yesterday... with RDA slotted rotors and greenstuff pads from the GB.

They work really good and have a very good bite.

I have notice a very soft squeal from the pads tho when braking at low speeds and it only occurs sometimes... I am running the metal shims in the front and rear calipers. EBC did provide some plastic type shims, but i choose to use the metal ones i already had... Could this be the problem? Or is it common to hear a little bit noise during the bedding in period?

Ive done the 8-9 60kms-10kms runs when i first put them in and now i am taking it easy for the next 100ks per instructions....

Any thoughts?

threw a set of lucas pads on my stock r33 gtst before the last sandown event.

much better than the bendix heavies that were on there before. the first session they were pretty shiz, but in the 12 min sessions after that they held up

the whole way through. i did 5 12 min runs on the day. with rbf600 fluid most of the braking performance came very low on the pedal, not sure if that is

air in the line. but they held up well. the pads have now done a DECA, sandown and HH and have worn around 1/4rd down on the fronts and maybe half

that on the rear.

they were cheap at ~70$ a set.

just an update.

was getting 3 track days out of the trw on the front.

went looking for something that would hold up better and give better feel wen warm.

got a set of qfm.

pedal is much better, come on much earlier.

still only got 3 track day out of em on the front. but with much greater confidence in the pedal.

put some ducting in and larger 324mm rotors. have to see how they go.

still only got 3 track day out of em on the front.

Just to put that in perspective, I used to instruct at the V8 Race Experience at QLD Raceway, and we'd go through a set of Ferodo Formula pads in half a day, and those cars aren't being driven particularly hard...

A half day course we'd be right, but a full day we'd have to change pads at the lunchtime break.

happy so far with my hpx pads from greg. rears squeeled a bit the first drive, but quiet by the second outing.

whats peoples experience with winton and laps before fade occurs?

What car/brakes/fluid? All of these will be a factor. Most often it is fluid that brings on fade. Personally I've never had fade at winton with a 32 gtst with R34 310mm fronts. Good pads and fluid in most skylines will be fine.

Sounds like i wont have problem then. i doubt ill be getting near the mids 30's first time out like you are running. i was hoping around a 1:45?

gtr brakes front and rear in a torana, so its slightly lighter than a skyline, about 1200kgs. std dot 4 fluid.

Anyone tried the Endless MX72 pads? are they any good?? someone is selling for $350 for a set of front.

From what the seller, its replacement of CC-X, is CC-X good? I have no idea about these pads >.<

Please help!

CC-X are great. They are hard on rotors. It's still a lot of money for pads.

I just got the QFM A1RM's and they went well at sandown. Greg was very helpful and delivery was only 2 days.

Very cheap for $130. I don't think I'll be spending big on pads again after how they performed at Sandown.

I will monitor the wear but I get to about 220kmh before jumping on the brakes and they felt similar to my DS2500's.

RDA Blacks, purchased to go on the Pulsar as an OEM replacment pad. Car only sees daily and shopping duties so the pads were not super important to be the best in terms of performance.

I am not overally impressed, less stopping power than the Hitachi OEM pads and the modulation isn't that great. I can live with them and I thought I was being picky until my partner drove the car for the first time today with the new pads and she isn't happy with them at all.

Long story short they have to go and I will be using TRW Lucas pads or OEM pads instead.

PS does anyone know exactly what the OEM brake fluid used on an N16 is. I don't mean dot 3 or 4 but which particular brand or is it a custom nissan fluid.

Makes absolutely no difference because Dot 3 and 4 aren't performance standards, they're formulation standards. 99.9% of Dot 4 fluid comes out of the same factory regardless of brand.

using bendix ultimates at the moment for street use only.

pretty good at pulling up, a little bit of a squeel 1st thing of a morning with surface rust, and a little bit of a squeel at the end of a long drive (up highway for instance) but in between not much noise at all.

about a 7-8 /10

Yes I know what dot 3 and 4 is hence my question. There are huge differences between brake fluids even if they are the same ie dot 4 rating.

I have found the nissan fluid to be I think thinner providing a noticeably lighter pedal than castrol dot 4 and only slightly lighter pedal (better) than castrol super response dot 4.

I would like to find out what the original nissan fluid is exactly check the temperature specs to see if they are suitable for my track car as I would preffer to use it from a pedal feel perspective.

No chance. Standard Dot 4 or OEM fluid is good for about 250 degrees dry. To do any sort of track work you need a fluid over the 300 degree mark, like the 600 fluids that are 312 degrees dry.

I have been running 286 deg fluid along with quite few other regular track goers with the same car and brake setup. I have been using 700 deg plus pads and I regularly overheat the pads to point of fade without issue any fluid issues to date. The same fluid has been in the same car with DS3000's which I will be buying next and the fluid has never show any signs of boiling.

Keep in mind my track car is rated to use DOT 3 fluid only and Castrol Super Response DOT 4 is the highest temp DOT 3 compatable fluid that we are aware of.

I would use higher temp fluid that is DOT 3 compatable in my track car if there was some available, are you aware of any?

TRW GP600 Racing Brake Fluid, $65 for a 1L bottle, and good for 312 degrees dry. Conforms to both Dot 4 and Dot 3 FMVSS No.116.

My cars brake system I needs about 3lt per flush, I typically buy a 4lt container of CSR Dot 4 at about $40 amd flush the brakes the day before most track days.

How do the A1RM pads compare to the TRW Lucas pads in terms of friction, I see they are rated to 0 to 780 deg C which is probably the best temperature range pad I have seen to date but the friction is a little light on at only 0.4-0.48.

If you're changing standard Dot 4 before every track day, then that may be enough. Certainly going to a high temp fluid is an advantage, but where fluid looses it's edge, is moisture absorption. 6 month old GP600 may only be as good as brand new Dot 4. It doing that works for you, stick to it.

A1RM are a stack higher than TRW. Any normal street pad (TRW included) will be in the 0.35-0.43 ish range...

I see they are rated to 0 to 780 deg C which is probably the best temperature range pad I have seen to date but the friction is a little light on at only 0.4-0.48

Friction levels are pretty useless because there's no standard test for it. Manufacturers just release figures based on the equipment they use. For example Ferodo DS2500 are rated to 0.50 hot, but the majority of anecdotal feedback from that that have ran them back to back against the A1RM is that the A1RM bites harder when hot... Takes friction figures with a grain of salt.

True nothing beats new brake fluid but as per above I am not using standard DOT 4 fluid, I am using CSR Dot 4 which is a DOT 5.1 that is compatable with DOT 3 and DOT 4 systems. I thought CSR DOT 4 was the only DOT 5.1 backwards compatable with DOT 3 until your post of the GP600. CSR DOT 4 is rated to 286 deg dry which is a significant upgrade over standard DOT4 and DOT3 but not quite as good as you say as the RBF 600/660 and GP600.

A1RM are a stack higher than TRW. Any normal street pad (TRW included) will be in the 0.35-0.43 ish range...

Interesting, I have found TRW pads to have very high friction, higher than every other street pad I have tried even pads claiming 0.5 and I have assumed even though I cant find a spec for them that they are at or above 0.5u friction.

I have not tried the A1RM but by the sounds of it they could be a very good option.

Pointed noted.

The reason I asked was I have tried DS2500's and I wasn't overally impressed with them and before I fork out for DS3000's I might look into other options. IE the DS2500's were good but not great and certainly not worth the expense at 5 times the cost of TRW Lucas pads which had similar braking force, better cold performance didn't eat rotors but just lacked the higher temp range that the DS2500's provided.

I was hoping when I put them in to gain an increase in braking force not only higher temp range given other peoples comments about there experiences but I didn't find this.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
