brakes still squeeling damn brembos

[7heavn]

After having the discs machined on my vspec r32 gtr to solve brake squeeling problem it hasn't really helped the situtation at all . Pads that are currently in the car are of a soft compound and I've also tried sanding them down .

Sort of at a dead end to this problem it's a really loud annoying squeel and it has to go. A few people have told me that I should just put up with it cause it's what brembo's do but I can't imagine this car rolling off the showroom floor with squeeling brakes like this what do you guys think?.

Basically I've machined discs , applied copper grease, sanded the pads down , made sure that the backing shims are in place only other thing now is to change the pads , could I order factory pads from nissan?.

I have the same problem on my R32 vspec dude... had discs machines.. pad replaced etc. I have upgraded my front rotors to cross drilled ventilated type.. the bastard still squeaks.

I know how u feel.

I had the same problem, to the point where I was embarrassed to brake in traffic. I changed them to Winmax pads from Belperformance, and gained better braking with no noise.

Very happy!!

Hey ned

How much did the pads set you back ?, if they don't squeel will go and get a set straight away. It seems as only my fronts squeel becuase when I tried the copper grease I only applied to the front and it stopped the squeeling but not for very long.

Let me know 2 cause only my front brakes are sqeeling.... before i bought my car 6 months ago... $900 pads were put on... dont really wanna waste em for now... i can put up with the noise.

The noise is usually from the piston in the brake calliper oscillating because the pad and disc surfaces don't match up perfectly and cause harmonic vibrations. Your problem could be in the calliper.

Most people i've spoken too that understand the concept properly are involved with motorsport and couldn't care less about squealing brakes cause it doesn't hurt performance. V8 supercars always sqeal cause they throw new pads on rotors without being machined.

If you machine the rotor you'll have to skim the pads too. Try having the pad edge chamfered aswell.

Otherwise turn up the stereo. lol

track cars would be using a harder compound then a street car also I soppose . Mine are fine when cold but once the brakes warm up they squeel like you wouldn't believe when coming to a slow stop ,under hard braking there fine. A few people have told me just to live with it cause it's what they do. I don't believe these cars would have rolled off the showroom floor with such noisy brakes.

Too hard a prsure on the pedal might be the major problem.

Though going beyond that, don't grease the rotor itself, you only grease the back of the pad that touches the piston, to stop the vibration of the pad (if you don;t know) if you do grease the rotor it will make it harder to stop and you'll get the squeeling.

Another problem you can get is brake dust or brake pad dust, if you have to much it will cause the squeeling, use a spray brake rotor cleaner so you don't have to take the caliper completely off the rotor.

Anthor would be to change the pads, probbly the wrong type of pads for your driving style as top notch racing pads will squeel as they arn't up to the correct temp etc, so dropping back to more street type or semi race type pads would be better.

I've read that the endless g spec are good for street and race track, but they really dust up.

Another thing to check is the brake ratio as too much presure could be on the front brakes might need to change that as well.

Get the backing plates/shims bonded to the pads. It fixed ours. Good luck.

I'm in the same boat, there's a thread on the brakes/susp/handling forum on this. I'm using Ferodo 2500 pads and freshly machined DBA 5000 discs and the thing squeals so badly it's almost impossible to stop at low speed with the window down, particularly when there's some heat in the brakes. The 2500 pads have a rep for being noisy on some forums but this is unacceptable. Like you I simply can't see how they could possibly have been this way new.

I've tried stick-on Mintex shims and it made no difference. Tried scuffing the rotors and pads, no change. Slight chamfer on the edges was a waste of time. Have had the edges chamfered heavily and we'll see. Part of the problem could have been the cooking of the discs by the previous owner; they were extremely glazed and so hard they couldn't be machined on a lathe because it chattered itself stupid so they had to be milled.

New discs are on the way and so are EBC Greenstuff pads. Will keep you posted.

Can I ask what pads you are running? You also mentioned shims, are they the stick on type? I wasn't aware that Brembo pads run with shims of any type.

pads in there at the moment at lucas pads . The pads do have backing plates but they aren't attached to the pads themselves.

[Jolinator]

have you tried spraying the back of the pads with anti squeel spray, you can get it in an aerosol can, normally red, it works quite well

[7heavn]

yep tried that.

Obvious question but are they a street or track pad? Do your rotors look really glazed?
