Brakes Constantly Squeaking

[barnoon]

Hi guys,

Ive been having a really annoying problem lately with my brakes, they squeak CONSTANTLY I mean like even when their not in use the rear left squeaks as im driving along not using the brakes at all it might stop for 20 secs here and their but its very rare. I changed the pads to brand new ones and the problem was still their so I took it to the brake place and they said my discs needed machining so I got all the discs machined and all new brake pads all round. Drove out of the workshop all was fine for about 3kms and I was enjoying being able to drive without the ear piercing sound of the brakes squeeling constantly but then all of a sudden the noise came back and its been doing it constantly just like before.

Anyone got any ideas what it could be thats causing this and what I can do to fix this (I cant get it back to the brake place until Monday as they are closed now)

mine is doing a simalar thing, some times it does it some times it doesnt, stops when i apply brakes, very annoying isnt it!

Yeah man mine stops doing it when I apply the brakes too! It annoys me so much I try to drive the car as little as possible its so embarrising its the most ear piercing sound ever.

well check your brake pads would be a good way to start to see how much meat you got left. maybe you can change to a different brand pad also because some are known to squeal. I use to have dodgy squealing ones then changed to bendix and all good now

Have changed brake pads twice mate, last time was Ferodo, this time Bendix (brand new put in yesterday)

[justin911]

are yours the bendix ultimates or the normal ones ?

my ultimates do it.. if i use that spray stuff it fixs it up for a day or 2

Im fairly sure their just normal Bendix pads, the thing is they dont squeak at all when braking, its the cruising along when im not touching the brakes at all that they continuously squeak, as soon as I apply the brakes to slow down the squeeling stops.

Have you got the backing plate on the pads? If not, get some OEM nissan backing plates and install them. Often brake places will leave them out as they dont usually come with aftermarket pads.

If you do have backing plates already: get some anti brake squealing stuff from repco. Its called "Squeal stop" or something equally as obvious. Just ask at the the counter. It's a red goo that you apply to the back of the pad to stop it vibrating. It's not a commonly known fact - the squealing sound is actually the brake pad 'rattling' at high frequency inside its housing, so adding some packing in there (backing plate) or some shock absorbing material (squeal stopping goo!) will solve your problem.

I found that the goo works well for a few months then needs re-application. Best off getting some proper backing in there (oem works fine) to provide some absorption for the annoying squeal!

Good luck

damn i was hoping the normal ones fixed it

mine do the opposite and just squeel when im coming to complete stop

Thanks mate ill go down to Repco tomorrow and grab some of this stuff hopefully it works

Update:

PROBLEM FIXED!!!

Turned out it was the shim plate thing was rubbing along the disc constantly even though the pads were brand new, got my dad to look at it today and he solved the mystery for me, went on a nice squeak free drive after that.

Cheers to everyone who offered advice.

Hmm.. Well good to hear that you got it sorted, but i'm a little worried about what you just explained.

From the outside to inside, the order goes caliper/piston, shim plate, brake pad, rotor (disc). Theoretically if they're installed properly then the shim plate and the rotor shouldnt come close to touching because there is a chunky pad between them. Anyway, you've got the issue sorted so I guess thats all that matters!
