I'm running the Alcon Advantage big brake kit on my R32, I believe they come with DS2500 pads, and they seem fantastic on the street, but I'm yet to try them on the track......I'm a little concerned they won't be good enough for the track (I tend to be hard on brakes by trail braking)

So what would be a good stage up from these? DS3000s?

I don't mind only using them for track days and putting the DS2500s back in for road.....any problems with doing this?

I would like something with a bit more initial bite, and like a firm pedal.

What power does the car have, the weight of the car. And what tyres and times at what tracks do you run.

DS2500s are not too bad and with 365mm rotors they would perform reasonably well...up to a point of course.

Also , with a brake setup like that depending on what your answers are to the above questions there is no reason why you cant havea pad that works well on the street and track

Hi Roy, The car is 630hp at the wheels, and I will be running some used 9" wide slicks that I can get from a local V8 class we have in NZ so there is plenty of grip

My local track is Ruapuna (Powerbuilt Raceway in Christchurch) and it does have a decent long straight, but has a very twisty infield that makes it a bit hard on brakes.

Advice on new Pads (and braking issue).

R32 GTR - 330 awkws

ABS

Brembo Calipers off an r33 GTR V (fully refurbed by PBR)

New DBA4000 wiper sloted rotors

New HEL Braided lines

New BM57 (match calipers 17/16")

New 600FF fluid

New Bendix Ultimate pads (absolute shite, spongy as and I don't know why).

Edit: Pedal doesn't reach the floor and neither is it hard as a rock. Just SPONGY.

I need to feel the brakes and I'm nervous when I use them as pulling up is a task @ 80-100+ kmph. It stops but just no where fast enough and without feeling like stopping.

Bled 5 times (by 3 different shops, last time pressure bled. Changed fluid 3 times, No Vac leaks, no brake fluid leaks, valve works. ABS works and sensors fine, Booster is working. All tested time and time again.

Correct bleed order followed, including ABS system.

So now I'm changing the pads F+R. Trying to achieve better feel and better stopping.

Spirited street and country driving and hoping to track 4 times a year. if I can be confident it will slow/stop!!

So questions.

  1. Will changing pads make a difference to feel and stopping power (it's very pedestrian feel at the moment :( )
  2. What pads recommended based on above info and
  3. Anyone recommend adjusting the push rod and/or pedal ?

and the big question - What da fuq is wrong (no it aint me :P)

Hey mate,

In short, the pads are your problem and new ones will change the feel and stopping power. Bendix ultimate should never be fitted to a car as heavy and powerful as yours ;)

I have DS2500s on my 32r and even they have the same issue to a lesser extent than you.

On my old car I became accustomed to using race pads at all times, once you get used to race pads it feels like you cant stop when switching back.

At the moment im choosing between Ferodo DS Uno (replacement for DS3000) or some Endless PC35. If the were the same price I would choose Endless for sure, but the DS Uno are $269 and PC35 around $420 from local shops in my pad shape.

Thanks mate - appreciate the response.

I'm hopping it is the pads and maybe poor bedding in by me.

Putting on Project Mu's HC+ early next week. Likely overkill for what I need and hoping they run ok on the street as well as the track.

I Didn't know about the squeal these pads make until after purchase. So going to have to get the Anti Squeel shims. Hopefully wont be too bad.

  • Has anyone heard of bleeding GTR brakes with engine running ?

No problem! Given your brakes have been bled a few times I doubt mistakes would have been made every time.

Im sure the HC+ will fix the problem but I have heard those pads squeal badly, hence why I would rather just go for a full race pad rather than a street/track pad that squeals anyway :)

Btw in case you are used to non ABS Nissan brakes, all the ABS equipped cars do feel heaps spongier in general. Because your new pads will have heaps more bite it will cover this up a bit.

Im going to try out the PC35s on a mates car tomorrow before making up my mind.

yes ABS so likely part of my concern also

post back and give us a view on PC35's if you get them please.

I went for a drive in my mates car with the PC35s but wasnt able to get them hot (light car, big brakes, urban driving!) they felt very aggressive when cold and squealed heaps, very similar to the DTC-60s I used to have on my old car. I have driven another car with the PC35s and they felt great but not sure if its comparable since that was mid engine.

Interestingly, I also tried another car yesterday which had DS2500 (same as mine now) and they felt way more aggressive, im pretty sure my current 2500s are stuffed since they feel nothing like they should. I overheated DS2500s in the past and they still worked fine but fell off off the backing plate in fiery chunks so I cant imagine what has happened to this set lol.

So i went ahead and ordered a set of Endless N35s which are meant to be slightly less aggressive and more progressive than the PC35 however handle the same heat (around 800 deg). Should have them in around 3 weeks.

Plan failed, cant get the right pads from Japan and dont want to pay $430 locally so im looking into other options.

In case anyone needs new pads, Nengun is doing an awesome deal:

http://www.nengun.com/project-mu/brake-pad-campaign

Buy a front set get a rear set free until mid June.

I've ordered some Project MU RC09 Club Racer Pads front and rear from Marty at Motorsport Brakes, they are a new compound from the same stable as the PMC pads the V8 Supercars use.

They are a stage up from from the HC+ pads so should be good, hopefully still ok for the road too.

So i'm looking at doing my brakes at some stage soon, wanting to get DBA 4000 Series T3 rotors all round. Pads wise i'm looking at EBC Redstuffs. Anyone have any experience with this setup?

I liked the look of the Project MU deal above too, quite cheap, but wouldn't have a clue what "series" to go for. Car is street only, no track at all.

Hey mate, Red stuff is probably too much for street only. If you dont drive the car hard on the street then I would say go for a less aggressive pad. I have had bad experience with red stuff so generally wouldn't recommend EBC but for street only purposes im sure they would do the job.

For a street only driven car I would bother with getting pmu pads from japan, there is decent cheaper alternatives locally like EBC, Ferodo, QFM etc.

Thanks for that mate. It's interesting that when you look at any of the common performance workshops around and what they stock, none stock EBC pads. Either PMU, Ferodo or Bendix. Makes me think the EBC hard to get, unproven or not that good on rotors.

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
