It's been a year or probably even longer since I put on QFM brakepads. I did not get the rotors machined as everyone I've showed them to, said they were fine and did not need it.

The problem since going onto QFMs has been the dust AND the noise. They squeel so much. I've taken the pads off and re-applied that special blue brakepad grease stuff at least 3 times now. It fixes things for a few days, then it goes back to total crapness.

What have I done wrong? I just replaced the rotors and brakepads on a family members Pulsar. No shims, no grease, nothing. And the car is silent as can be. It was just the cheapest pads and rotors they had at Bursons.

Should I have machined the rotors? Should I go get them done anyway since there is a local place that will do them for $15 each if I take them off the car and drop them in.

My previous pads were Nissan Hitachis and were silent with nowhere near as much brake dust.

Am annoyed I've not been able to solve this :(

Sounds to be the brakes pads are either the wrong size or not properly installed THEN you also need to check if your Pistons are hooked up properly. I had the same problem turned out they used aftermarket brake pads and it was the wrong size so kept making that squeaky sound.

To address the actual problem.....if you did not machine the rotors (and I agree it is not always necessary) then it is definitely one of the things you could/should try. Get a nice fresh surface without the old pads' binder material baked into/onto the cast iron. You'll want to scuff the new (but used) pads on a smoothish concrete surface to deglaze them and knock off any hard spots.

While you're working down there, check the runout on the wheel bearings, make sure there's not any movement in places that there's not supposed to be (like the caliper mounts), make sure th brake pad slider pins are clean and smooth, etc etc etc.

Street car? Remsa pads, fkn awesome and cheap as broooo.

Bro you helped me install the QFMs when I bought your KYBs and Hardrace castor rods a couple of years ago. Yes it's just a daily driver.

The QFMs still suck. Yes I could just go ahead and replace them, but want to get my moneys worth out of these QFMs unless there is a market for second hand ones. I can't comprehand just how bad they are. The car stops on a dime, but I pay for it in squeel and dust. And that's why I picked QFM in the first place after reading reviews on dust from other brands. How much did you pay for Remsas?

I just recently bought some Protex I think it was pads and discs from Bursons for a family members Pulsar. No shims, no grease nothing. Just used a metal brush and cleaned the hub and installed them. Silent! Pads were only $39 for set.

If I go machine the rotors then maybe I should just get a new set of pads I don't know. But then I fear doing all this and they still squeel. That would suck.

Mine squeal horrendously when coming to a slow stop with remsa / roadhouse pads, They get worse the hotter they get. Using t3 rotors, braided lines etc.

I've tried bedding in - this makes it worse,

crc copper grease,

brand new shims with oem grease,

roughing up the pad,

cleaning the disc,

sanding the disc with 1k paper

I'm at that point where i am going to buy bendix pads. Trouble is that i will be left with remsa that are barely used and were bought because they're a crossover pad.

I'm onto my third set of Remsas now, also with T3 rotors, HEL braided lines etc. Stock R34 GTT calipers, never had any issues with noise, off or on the track. Strange.

I've also just pulled my anti squeal half shims out to try to address unever pad wear, was fearing for the worst re noise, nothing.

I had the rear tyres replaced today. My rear rotors look to need machining. Is it worth trying to use the old pads? They are about half used, or just chuck them and start fresh with the machined rotors? I won't go hungry if you guys say yes, but it just means more money I cannot spend on the respray and then nistune/turbo replacements.

no pads will cause squealing; no manufacturer put a compound together, glued them to a backing plate, stuck them in a car for a test, heard them squeal like a pig and said "great, let's get them on the shelves". And I mean up to and including sprint or endurance race pads.

Yes some more agressive pads are more likely to be noisey but it is always a problem with the car and/or installation.

Squeal is a high frequency vibration in something that shouldn't be moving. Like GTSboy said above machining rotors and pads may help if they aren't new (flat), any moving parts like sliding pins, caliper pistons, touch point between pistons and pads (which should be anti squeal shims), hub to disc mounting surface, caliper bolts tight. By far the most common cause is simply brake dust, so get everything nice and clean when you reassemble.

If the noise goes away when you add anti squeal goop between the piston and pad that tells you the problem is likely in that contact somewhere. So clean and check the shims are not bent etc

Intima SR for street car

Wow 700C temp rating, higher than the A1RM. How do the SR go on the track?

My Intima SS's died on the hills, need some convincing to go back to Intima after that..

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • 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.
