nismoman18 Posted July 16, 2003 Share Posted July 16, 2003 well i got RB74 front pads, and they squealed when no brake was applied, when applied it is quite normal for them to squeak. So i got my discs machined cos they were warped and had a lip, wow it worked! no more squeal. BUT i was at the track today, and after the day they now squeak again and very annoying! The discs i think are too thin to be machined again, wat do you reccommend ? new discs ? or could it be some thing else like dirt stuck between pad and rotor? please help me Link to comment https://www.sau.com.au/forums/topic/20662-rb74/ Share on other sites More sharing options...
Airzone Posted July 16, 2003 Share Posted July 16, 2003 I suppose you could take the pads out and brush them off and clean off your rotor... That should make sure there's no crap there...

Roy Posted July 17, 2003 Share Posted July 17, 2003 Maybe the pistons arent retracting all the way, my car had the same drama, you could always hear the pads rubbing on the rotors. It wasnt until you pressed the pedal and the pad was in full contact witht the rotor that the noise went away. Had the calipers re-built, now they are as good as new.

JimX Posted July 25, 2003 Share Posted July 25, 2003 When you machined the discs did you sand back the pads as well? Both pads and discs will become glazed over time, and if you scrub one back without the other, the one you scrubbed back will just get glazed again really quickly and you'll be back to where you started. Could be the discs are too thin too, things will glaze up easier if there's a lot of heat involved. I think new DBA4000 discs are around $200 each. It may seem expensive, but they are probably a lot cheaper and definitely a lot better than the OEM items. If you are really pushed for cash, maybe try buying someone's second hand discs? If you do, make sure you check for run-out. The factory items are 30mm thick when new, and need to be replaced at 28mm.

Roy Posted July 25, 2003 Share Posted July 25, 2003 Its not cheap, and you cant be sure that calipers need rebuilding until they are apart, then its too late as most of the expense has already been incurred. If you need new rotors then that is the logical place to start. People laugh at the lengths i go to, to make sure my brakes are properly cooled down after each run at the track. Its all you can really do to stop them from warping/cracking, that and not using the handbrake when you park it after a run.

nismoman18 Posted July 26, 2003 Author Share Posted July 26, 2003 the pads were brand new when i got the discs machined, they hadnt been bedded in yet. The machining took the squeal away after the track day they started to squeak again. The calipers are fine, dont need a rebuild, its most likely the discs are quite thin so theres still abit of warp in them. I will live with it for now as its on and off thing (hard metalic pads create squeaks) im looking to upgrade to GTS-T brakes in the future without a stud conversion, the calipers can bolt straight on, they are just fatter and i might need new wheels Thnkas for the help ppls, Ben i dont think i will buy them, thanks neways im not sure if the GTS-T discs are much bigger? as the pads are the same size Roy- i always drive around the track again using no brake to cool them down and i dont use the handbrake to park either, but its only the fronts which squeak, id say its the thin discs and new pads. with the standard pads i used them twice on the track and they were gone, ive used the race brakes once and they havent even lost a mm and that was real hard braking Link to comment https://www.sau.com.au/forums/topic/20662-rb74/#findComment-450596 Share on other sites More sharing options...

Mildman Posted July 26, 2003 Share Posted July 26, 2003 My recommendation is slotted rotors too, since I have fitted them to my car, not only do I get a lot loss fade on the track, but no squeak either...more a low pitched groan under heavy braking as the rotor chops up the pads. DBA's are good and reasonably priced, check their website www.dba.com.au Link to comment https://www.sau.com.au/forums/topic/20662-rb74/#findComment-451213 Share on other sites More sharing options...

JimX Posted July 28, 2003 Share Posted July 28, 2003 How much are the Comp 15 pads? They seem to be the next step up from the RB74's. How are they for rotor usage and dust?

Your the team manager, and im the backward a55 driver. Hey, and i dont rev yours over 4,500 - 5,000rpm, you have seen how i drive my car when i get excited. Me in my car = Drive:mad: Actually, i think i should just say thanks for the drives, and think of ways to thank you, need your car detailed? As for Comp 15 pads, PM Silver-Arrowz, i think he uses them, may have been Comp 9s and whatever he is using is hard on rotors.
