What The Heck Is That Squeaking Noise From My Brakes?

[Spunky Munky]

Hi all,

I recently upgraded my brake pads to Endless ones and started noticing quite loud squeaking noises from my front disc brakes. It's really irritating and somewhat disturbing...I mean, I paid extra cash for performance and safety not this sound.

I've spoken to a lot of people with performance vehicles and their brakes also do this sometimes. I have a few people run up to me and say, you've spent so much money on this car no doubt with the exterior and performance upgrades etc, time to give your brakes some attention - and I was like "yeah, I know and I did do that...."

So fellas, how the heck do I stop this - is there a way and if not, is this normal? I came across an interesting article online and thought I'll post it here...how much of this is true...please explain...

Thanks all...

Which compound are they for starters?

What did you do to bed them in?

Have they seen a decent amount of heat yet?

Did you use the shims that came with the pads (if they came with them), or used your existing shims and used copper grease on the shims? Lack of shims can explain the noise

I dont run shims, I don't get squeaks, I run decent compounds.

I assume your rotors arent warped and you skimmed them before you put new pads on?

Do the obvious and cheap first ie, lightly sand the pad surface and bed it again, otherwise you might glaze the pad(forms silicon like stuff and hardens up).

Try bending your existing shims a little and see if that helps.

If no go, then try putting some of that red brake glue that you spray BEHIND the brake pads. Anti-squeal shims. This fixed my issue - Adhesive brake pad stickers($4 for pack of 8 from BNT).

If all that fails, it might pay to check to see whether the pots(name) are actually pushing onto the pad evenly. If one of them isnt pushing out fully, then that may explain your squeal.

haha sounds like a bit of sooking here

happens with decent pads sometimes... might be shims might not be

if you care more about the sound than having good brakes go back to your normal street spec pads

I have same problem I have Dba slotted rotors with Ferodo Ds2500 pads work excellent and have been for a year. Then all of a sudden now my fronts are starting to squeel there arse of so embarassing really I've spent a fortune on my gtr and this shits me to tears, pads still have lots of meat rotors have no lip as car never tracked just driven hard like a gtr should be. So to any in the know maybe my discs might need a very very light machine as it looks like they have smoothened out a little could this be the case the pads over time being a course compound do this.

Any thoughts?.

Cheers,

Dave

if you want a quiet car get a luxobarge, you have a gtr... its gonna make noise.

there is a reson you can have a skyline that performs as well or better than a half million dollar lambo for 50k

i'm guesing you didn't bed the pads, as you never mentioned it in your post, so take them off, rebed them, put copper grease in the shims and put them back on...

beyond this, just deal with it

yea i got the same problem atm. i have 32 gtr brakes with bendix ultimate pads and its the front that makes the noise. however when i inspected it the pot had been worn unevenly on the pad and so the rubber sticker bit was showing the copper/metal bit on the pad.

i used the anti squeal lubricant but that only worked for 10 min. im not sure what to do eather????????

cheers Evan

Thanks Hamish yeah its cool having a car that performs better than half million dollar Lambo but my brakes never squeeled for a year! of hard driving, but i will take your advice into consideration as i have nothing to lose and all to gain that might work.

And yeah i did bed them in good.

cheers,

Dave.

[joeyjoejoejuniorshabadoo]

just try copper grease on the shims.... i re-apply mine every 15,000 and it keeps them quiet

[Mr GTR-32]

Cheers hamish will try that.
