Brakes Squeeking

[Cassbo]

Squeaky brakes make your car sound more like a track weapon.

The bishes will love it, embrace the squeal.

Quoted for truth

I use Project Mu HC+ pads, and in my experience they don't go quiet until I give them a good pounding at a track day

Just need to keep an eye on them as they don't have wear indicators

Hi Guys

If it makes you feel any better I have a VE HSV R8 with DBA5000 Series and 2500 Ferodo Performance pads.

Squeeking...........Drives me nuts!!!!!! The replacement pads and rotors are heaps better then the factory crap but oh so loud. My wife drives the car most days, but when I get in it on weekends it does my head in.

I'm looking at buying an R33 for weekends so I thought I would see if I have the same trouble.

Cheers

I guess this thread somewhat answers your question lexasty.

I gave the brakes a hard time the other day and they seemed to be quite for a while after that. The more I drive it sedately and brake lightly the noise comes back and gets worse.

So I gather the temp rating of the pads I have is too high for the main usage of them. Hopefully I'll have quite brakes when I get a pad more suited to street driving with lower temp rating.

[lookingforboost]

mine make a high pitched squeeking only on the lightest touch on the pedal then nothing and when cold they are so loud!

i have put on DBA 4000 wiper slot rotors and bendix ultimate pads i am going to put some stuff behind the pads cant remember what its called but someone told me it will fix the noise when driving when cold i know that it will always make noise

Its because you glaze the pads. Theyre designed to be alot hotter, so if you keep using them when they dont get hot the glaze over causing the squealing. Rub them on a bit of sand paper and put them back in. They'l be quiet again for about 30 mins

Right you are!

I did have the pads out as I knew that would be the cause of the noise, I also scuffed the pads up and it did fix it for about a day or two.

The reason I posted here with my question is I wanted to know if there was something I was missing with the skyline as to why the noise came back. The answer being pads that are aimed at race use not street use.

I've only heard good things about the QFM pads so I think I'm going to go with them.

[J34]

I've got QFM pads at the moment and they squeal so load it hurts my ears.

I think cleaning the shims and applying some copper grease is the go. Is there a specific way the shims should be put back together? There's a small clip tab thing that goes in the corner, does it matter what side?

Also whats the best way for resetting/ pushing the caliper pistons in?

[R34 -_-]

Mine only squeek at low speed only just noticeable after changing the pads a few months ago

I actually never worked out whether there was a 4piston caliper pusher :s

I did it a naughty way , one piston at a time.

Start with one, (cap off master cylinder), push it in however you figure out how to, put the pad in horizontal. Then press the bottom one in and swing the pad back down vertcal.

Repeat for the other side.

I found that was the only way i could do it. As every time you squeeze one piston in, is fires the other three straight back out

Anyone know of a 4piston pusher? Cheap? I had a single pusher for my Hondas... worked a charm and was only $15.

If your 2500's are squeeling the solution is simple. Get some temperature into them. Seriously - give the brakes a pasting for a few minutes and they will quieten down for a good period after that. When it happens again a few weeks later repeat the exercise.

I have QFM pads front and rear too. Front and rear used to squeal terriby. Gave them a very good pounding on the freeway late at night, about 5 stops. After that the fronts were fine but rears still squealed, i couldnt get enough heat into the rears to burn all the crap off the pads/ So taken out the rear pad and put stock ones in, easy fix, now its quiet all round. Then next track day i'll put the QFMs back in so they get a good workout and see how they go after that. Hope that helps.

Agree with this!

Also the thing is, most people put new pads in on the rotors they currently have. The rotors that are current have been bed in with different pads. So the best idea is to skim the rotos BEFORE putting the new pads in. Or, new rotors.

Then bed them in like a bastard.

When i was trying to stop mine, i tried every method i could think of, and still it came back.

Put new slotted rotors on (that also help with pad glazing), scuffed the pads, and went out and bed them in by giving them a freeway beating. 5 or so 100-50s calmly to warm them up, then the same, but aggressive 120-30 (about) to get them really hot. Did it a further 3 times, and the smoke was pouring off them. Parked up and let them cool off completely.

Havnt heard a peep from them since. (6-8 months)

wow, i will give this a go with mine, i have noticed over the last few thousand kms that it is starting to quiet down a fair bit but still got the low speed noise.

You should have got some bedding in instructions with the pads.

Basically this involves running them up to a temperature until you can smell them by doing repeated 120-80 (Or whatever you feel comfortable with) stops.

Once the pads have been bedded in properly they should be pretty quiet as a rule and, for that matter, work properly.

or you can just use the pedal on the right...

So if i want to stop, i hit the accelerator? f**k me iv been doing it all wrong!

You can buy a tool from your local auto store, I think they are called brake spreaders. Will set you back about $15-$20. I wouldn't bother with it though, I had trouble finding a leverage point for it to push the pistons back in and ended up using my fingers (ouch).

The QFM hpx brake pads dont squeel. Dont know why you guys are getting squeeling from them, you've probably got track ones on

Thanks for the info guys. Might take it for a spin tomorrow and give the brakes hell.

Anthony from Dahtone installed the pads and rotors and I think he had fun when he bedded them in.

Yea i think it's a pretty new technique you have to plant the accelerator do a 180 and then use your acceleration to slow yourself down. Not very effective, fuel efficient or safe but yea everyone does it cause it's mr cool

I didnt get any but i knew i had to bed them in so i did 50 to 0 fairly fast about 10 times then went to 80-0 about 5 times and they were great and i could smell them the noise only started the next day but i just thought it might be the rotors as they were new.

it stops very well and i am pretty happy with them when i get the new rear rotors and pads i'll get the brakes bleed with new fluid and give them a hard time see if that makes then a bit quieter
