Squeeky brakes and crunching noise..

[Haysey]

When my rotors are cold the brakes like to squeak...

also when alot of pressure is applied to the brakes when stopped there is a crunching noise.. kinda shound like the pad is slipping on the disc or something.. it happens with both front brakes only....

I have been told this might be the piston being dirty etc?

should i take them out/ give them a clean and a bleed?

brakes still work fine but can feel this crunching through the pedal when heavy braking...

Its an R32 with the bigger brakes with nissan on the side..

thanks

has this happened recently after u changed anything?? could just be the pads maybe??

my friend had this horrible crunching when breakin in his A3 turbo.....audio mech said it was something to do with his ABS unit/sensors or something like that. probably irrelivant but something to consider?

Definately take out the brake pads and give them a check. Easy to do, minimal tools required. TAke off wheel, and the on brake calliper make sure the pins are all in ok, then take them out and check the pads. Make sure the shims are in place correctly. there is a thread on how to take out/check them etc. are the brake pads new? are the due for a replacement? shit brake pads can be the cause of this. give them a sand all over with emery/sand paper to take off any glazed parts of the brake pad. Check rotors - is the rotor surface smooth? any ripples? perhaps you need your rotors machined and made nice and smooth. good luck.

i think the pads are reasonably new...

ill take them to a mate and we will pull it all apart and have a look at it...

kinda sounds like the pad is slipping on the disc so that might be it.....

will let u know the verdict..

thanks for the help guys

Hi i'm also having the same problem with my r32 have you had them fixed if so what was the cause of the problem?

[Zahos]

does it have ABS?

All cars with ABS feel like they are falling apart when it kicks in.

You should be able to tell if its she ABS, coz you can feel the brake pedal moving under your foot as the brake pressure is automatically adjusted.

Sounds like the pads. I had a crunching grinding noise when braking. Was caused by worn rear pads. Check your rotors also. Might be ablr to see rings in them where metal has ground out ridges in them. I had to have them skimmed back to smooth them out.
