New Brake Rotors And Pads... Squeek And Screech

[Ezy03]

hEy guys I got a mech to put on my new rotors and pads on for all corners and at very low speeds about to stop at a red light or going to park I just hear squeeks and screeches so noticable that wen I go to pick up my friend they say they know I'm heere cuz of the noise... Just wondering what possible reasons this could be happening? They are all new and just put on last weekend rotors are rda slotted and pads are qfm pads

Hi there, i believe that rotors and pads need to bed in so maybe that's all that needs to take place.I have a 03 250GT and i too want to change my rotors and pads,out of interest what did you pay for the whole package.

[Ezy03]

I think it was like $150 for the pads all up and somewhere around 500 for the rotors all up (I have to check around my pm's for exact prices shoot me a pm if u want exact values... I got them off this fourm aswell so if u search around u will find em.

google on proper bed-in procedures for new pads

having said that, some ceramic pads squeal even after proper bed in.

I've got rda slotted and qfm pads. If they are the A1RM pads then being a performance pad they can squeak a little until you bed them in properly.

Even then I found the need to occassionally give them a single hard application to keep them absolutely quiet. Once you have tracked the car they seem to be ok from then on.

The other street only pad compounds should be fine with just a bed in procedure- Usually accelerate to 80kph then brake moderately till about 10kph. Do not stop instead repeat 80kph to 10kph braking at about 1minute intervals about 6-8 times and then drive around for a few more minutes to cool the brakes down.

If they still squeal your mechanic may have made a mistake in assembly of the anti rattle shims so take them back for him to have a look at.

I got new rotors and pads 12 months ago and mine still squeek, Ive had it fixed a couple of times and the squeeking goes away for a short time before its back again. May be the make of pad or something, I'm thinking of changing brand, maybe EBC or something, anyone suggest what they have that doesnt squeek?

hey guys, well today the brakes have no/very little squeek but tonight as im driving to my mates place when i press on the brake it feels very fient and i have to go 50%-80% in to get a good feel (but still feint) for the brakes - before i use to just tap my brakes and the car would slow down it feels like its dropped maybe 50% of its braking power - i cant/dont feel a solid feel when i put my foot down on the brake...also i dont feel as confident braking now as i did before with my old pads and brakes (i think i do have the a1rm qfm pads)......anyway from the can any1 share some insight to possibly wat might be wrong? cheers

that sounds like you might have air bubbles in the lines in which case you need to bleed your brakes, or your brake fluid might be stuffed and need a change? Im no expert but i made sure my fluid was changed when I did the front discs and pads on my 350gt

[mosoto]

OR your mechanic put a large dob of Silicon anti squeel between the shim & pad

I've used EBC pads & RDA slotted rotors for a few years now and have never had any problems with brake squeel. It's important to instal the supplied shims correctly and bed the brakes to manufacturers spec, as grae35 mentioned above.

also important to get the correct pads based on your usage. if u get race pads that are meant to operate at higher temps...chances are that cold braking will be sacrificed

Hi thanks for your reply i'll have a scratch around the site thanks

Hi i'm looking at getting EBC ultimax rotors along with redstuff pads looks the part and good price cheaper in the USA than UK but frieght a killer from USA, i have part numbers if you interested,cheers

[Son Gokou]

I heard Lucas TRW pads are pretty good too!

[180 wanabe]

I used ferodo DS2500 pads on my 180sx which had R33 4 pots. Worked fine when cold and so much better when on the track. Where the pads that I had before would give up after 3 laps these ones just kept on working!

So for anyone who wants a good street/track day pad I highly recommend

sorry to hijack, but similar problem..

My brakes dont sqeak, but there is a noise when Im driving - Im guessing a pad is touching a rotor or something slightly on rotation as the noise gets faster at speed.

You cant hear it with the windows up, but when they are down it drives me crazy!!

any suggestions?

[Kam-80]

What does the noise sound like? Sometimes it can be put down to a stone or something similar stuck in your heatshield.

I have Project Mu HC+ and titanium shims...when I stop at traffic lights old ladies curse and children's heads explode. I argue that it's a good safety device, just to let everyone know that I'm around.

[Walf]

yeah it sounds as if something is stuck somewhere.

pulled the wheels off last weekend and had a look, couldnt see anything tho

[mosoto]

If not the brakes then I'd suspect wheel bearing.

[RWG]

I agree could be a bearing, on the other hand it could be the backing plate touching on the outer circumfrence of the disc maybe whilest changing the pads etc your backing plate could have taken a tweeking, just maybe, check it out.I had it on my car but that,s because the way they stack the car's in the container they have to remove the wheels mine must have been on the bottom so it was sitting on the backing plate and they do cover the disc slightly so they bent with the wieght and were rubbing on the disc, hope you find the problem, cheers.
