I got my ralliart brakes put on a few weeks back and ever since then I have had this loud annoying noise coming from (I think) my rear wheels. Its not high pitched like you hear sometimes when you brake, rather a noise very similar to what you hear when a huge truck brakes heavily. ("Uuuurrrrrrr")
It is prettttyyy loud.
It happens whenever I apply the brake, but only when they are cold!!! After 2 mins of driving, the noise has stopped. If my car is then left for a while to cool down, the noise will usually start up again when I hop in and brake for the first time.

I usually hear it when I reverse out of a car park (Whether at the shops or at home) and after than initial brake, its gone. It is so loud though and very embarressing at the shops as people stare at my car.....

The other day the sound continued for around 15 metres of me driving, but this time after I had applied the brakes for the first time. It got louder and quieter with each wheel rotation.

Now when I did my brakes, the handbrake was also not adjusted correctly (Was a bastard and a half to get the rear left disk off the handbrake setup, so this was adjusted via handbrake in car and on rear wheels). The handbrake is a little loose though, even though it was adjusted only a few weeks back. The noise is not heard though if I brake using the handbrake instead of the foot pedal. I dont know if it is there when I brake after I have used the handbrake though, might have to test.

I am now wondering what exactly is causing this terrible noise!! I have 3 guesses. Either:
1. Handbrake not adjusted properly.
2. Disks need skimming
3. The pads are really shitty (I was told that they were changed by mits, so they prob put their shitty mits pads on....)

What do you guys think?

I may have the same sort of problem... First thing in the morning when rear brakes are cold, When reversing i get a high pitched sound which almost makes my car sound like it has Truck reverse sounds on it :P
I don't know if they are linked but i'll be watching this thread for any feedback. Sorry i couldnt help mate, Just thought i would let you know your not the only one with the same problem :)

I'd be checking the handbrake set-up at the rear hubs before looking elsewhere.

possibly pad chatter from the new pads and/or incorrectly installed pad shims. Get your hands dirty and have a look yourself.

Thanks guys,
Took my rear right disk off yesterday (As we found out this was the one making the noise, could hear it just by spinning the wheel). Just spinning the disk was hard and it was making the noise whenever it got really hard to turn. We loostened off the handbrake (At the wheel and inside car) til it was just holding, but the noise is still there!!! Dunno what to do now...

Its going to be the shims not located properly or faulty pads. I know it sounds crazy (faulty pads, your a mad man) but you would not believe how often it happens. Given that its a cold issue, I suggest using a brake compound between your pad and the shim. There are plenty of types available from your local auto parts store and they work a treat. Give that a try and see how it goes for you. The locktite stuff is best. Just ask for brake anti squeal compound.

Hey Mate,
Yeah I thought it would be that too, but we took the caliper off and just spun the disk (With wheel nuts holding it on) and it made the noise.... :(

So with no pads in place, the noise is still evident? Well now, that is a dilly of a pickle. Are you sure its not intermittent bearing noise perhaps?

Is the disc rubbing on the mounting bracket for the caliper? You had ralliart brakes put on, that may be the problem - incorrect install. lol Just put the original bits back on. lol

I was thinking it may be a bearing also..

Its unlikely, but certainly possible. Bearings traditionally make noise or dont. Its not common for them to be noisy when cold and fine when warm but I have seen it happen. The only way to know for sure is to remove the whole brake assembly (calipers, mounts, handbrake shoes etc) leave the rotor in place, pop your wheel on and spin it. If you get no noise, its something in the brake system. Its simply a process of elimination.

Im pretty sure the install is fine, all 3 other wheels are good and basically everything I took off to do the install a few weeks back, I took off yesterday (The only thing I didnt do yesterday was take off the brake line, other than that it was the same process to remove and put on my ralliart brakes) Definately not taking off my brakes!! lol The stopping power of the ralli's are just so much better than the stocks!! So Id rather just deal with the sound than go back to stock..

One thing we noticed is that the noise did get louder when the handbrake wasnt done up tight enough and we turned the wheel (Without the calipers on, with the handbrake on).... So that leads me to believe it is something to do with the handbrake 'shoes' and the inner contact surface of the disk.... Dunno how its making the noise though...
We also did the bearing test by holding at 9 and 3 (And then 12 and 6) and trying to check for movement, but there was no play so I think bearings are ok....

Another thing I thought of today is that we did take the handbrake shoe thing off when we changed the calipers (Not on purpose, it fell off because we were adjusting the handbrake the wrong way and loosened it instead of tightening) The disk was off so not a big deal, we just put it back in place and tightened it like you would normally. Is there any chance that if the shoe was put on the opposite way to before, it may have worn on one side, so flipping it like we might have done would mean the shoes were contacting the disk a little differently than before?

Its possible. But at this point anything is possible. Is the inside of the rotor hat in good condition where it mounts up with the h.brake shoes?

I had a look at it...seeems ok I think. A much more shiny colour silver in the middle (Obviously where the shoes contact it), but couldnt feel a dip or anything when I ran my finger over it...?

Try roughing it up a little bit. Take the shine off the surface by giving them a bit of a rub down with some emery paper. Just make sure you clean the excess dust out. You might be surprised.

Will try mate, one thing though, wth is emery paper?? lol
There is actually basically no dust in there (Probably because the rotors where put on not that long ago...)

Another thing I might have to try is swapping the rear disks over and seeing if the same side still makes the noise?

Yeah, I mean the dust that will result from the sanding. Use a damp cloth to wipe them down, or rinse them with warm water and dry. Do NOT use compressed air to blow them. You could try swapping them over. You just never know unless you try.

Check the backing plate for rub marks. Also the caliper mount bracket. Spin the hub by hand with nothing on it, allows you to check the bearing for roughness. Compare the brake shoes on both sides. When you reassemble, check by spinning the rotor to see when the noise comes back each time you mount one of the components.

Will do mate, thanks!

The backing plate was touching when we first put the disk on, and it made a terrible noise when driving. We fixed that though (I hope) as this noise is completely different....
Anyway, will check everything again and do the above to the disks probably next weeked when I get some time! Thanks guys :)

This is starting to seriously annoy me now..... been working on it for like 3 hours again today and still dont understand whats going on!! I took the disk off and spun the hub and it is perfectly fine. I put the disk and the wheel back on (No caliper) and took the little nipple thing out of the disk so I can adjust the handbrake. At first if I pulled the handbrake level up around half way and spun the wheels, I would hear the noise. The handbrake was very loose though.
Now I have tightened up the handbrake to a decent level, maybe a little too high, but I now have constant noise coming from that wheel!! The other wheel is fine though! Arrgggg

Im still confused at why the noise is heard when braking when the car is cold as this is when im not even using the handbrake/?!! Wtff..!!

Im gonna try and upload a video to show you guys the noise...

Ok here is a vid.....

The handbrake is fairly tight so it wouldnt usually be making this constant noise as it is in the vid. it does however make the same noise though when the handbrake is set not as tight (Just holding with level all way up).

Does anybody know what this sound could be??? The RH rear doesnt make this noise...

That's steel on steel noise. Look at the sides of the shoes and see if there are any rubbing marks on them, and the inside of the drum. Are you sure those brake shoes are installed correctly? If its not that my money is still on the backing plate.

Sounds like your park brake shoes are shot.
