they are a brand new set of powerslot rotors with project mu brake pads. they only have about 250+/- miles on them and they're squeaking already.

 

you could try some spray on stuff that is meant to stop squeeks - dunno what it is called...

maybe they still need to be seated in?

t..

 

wow! it should lose the sweaks after like 250 miles of driving. try the sweak stuff he is talking about. the pads some times take a little to wear off the meat on the pad that touces the rotor.

 

Have you been getting "on" the brakes big time heavy? If so, it's POSSIBLE that the new pads have gotten glazed. More likely, though, is what the other guys here have been saying -- anti-squeal compound, or whatever the heck that stuff is called.

 

well, i haven't been stomping on the brakes that's for sure. i'm not sure, the rotors might be glazed. you guys be the judge:

When you did the install, did you apply anti-squeal to the 'prescribed' areas on the pads, shim, and caliper piston? If you didn't, you've probably located your problem. Just buy some (comes in a thick paste in a pack, I've not seen a spray before) and apply it.

Problem solved.

 

yes, i applied it to all the places you've described except for the caliper piston. as for my girlfriend's car, i applied the anti-squeal compound (honda of course) to all the places except for the caliper pison as well, and it doesn't squeak at all. but, those are honda brake pads.

 

it might just be the combo of pads/rotors. you might have to live with that sound

you could try sanding down/scuffing the rotors and pads. (i do it regardless of any odd noises whenever installing new rotors). i'll only sand down the pads if theyre glazed

just sand everything down, make sure the ears of the pads are greased (with anti seize)

 

I just installed power slots with Axxis pads about 250 miles ago as well. I didn't use anything special whatsoever. No anti-squeak stuff. I'm squeakless with the axxis pads but then again I haven't been anything BUT gentle on these new brakes so far. Good luck..

I've used the "anti-squeak" before on a jetta and it worked really well.

 

If it really drives you crazy and don't want to try a bunch of different pads- Honda pads are quiet- or you might try some AEM Nissin pads-

 

yeah what you've done is glazed the pads... basically they will squeak for the life of the pad. when i had my cross drilled rotors and axxis pads i was forced to do a heavy stop from 80 with 300 miles on them. the things squealed like hell for about the next 10,000 miles... then the car was stolen... you have to go easy on the pads for about the first little while. no highway driving should be included in your break in period. you can do highway driving. just don't include it in howlong you've been driving on the breaks.

 

isn't there specific process to break in the pads? did you do that? just curious.

 

my brakes were squeaking like crazy once... my dad told me to sand em down a little. I sanded down the pads and the rotors just a bit, and the squealing stopped.

don't really know why though

 

just curious as how you came to that conclusion. does it look glazed from the pics of the rotors? i've been gentle on them.

but, i'll try sanding down the pads and rotors.

thanks guys

 

did you have any kind of other pads on those rotors before the Project mu's?

 

no, both were brand new and installed at the same time. would the spray on "brake quiet," get rid of the squeaking? any other suggestions would be appreciated.

 

it's not the rotors that get glazed... it's the pad, and there's no way to tell you've glazed them by looking at them. another way to tell is if they don't stop as well as they used to. that brake quiet stuff is a bunch of poop 'cause all it does is attract dirt. try taking off the pads and sanding down their surface like suggested... just don't sand off too much...

 

Since you said you used Honda specified M77 molykote grease, this is redundant.

If you used the blue permatex stuff, the pad and shim might not be "floating" enough
as they are vibrating together as a unit because of the stickyness of the grease.

Greased BOTH sides of two inner shims and outer shim?

I had this same problem with EBC and found that Porterfield R4S pads are MUCH, MUCH better for noise.

Did you follow the 10-15 medium hard stops bedding-in routine after the first 100 miles (this arbitrary distance allows them to mate to the rotor some first) of use as some pad makers describe?

 

Straight out of Motor Trend's March 2002 Issue in the Car Care section:

Metallic brakes [tend] to make noise when brake dust accumulates. The easiest remedy is to aim a strong stream of water at each brake caliper for a few seconds each time you wash your car. That will flush the dust away from the brake pad and rotor, eliminating the source of noise.

 

Dang! That looks like my setup! Project mu pads, Powerstop slotted rotors, GSR wheels...

And those pads SUCKED. They never squealed cuz that means that they would have had to have some sort of stopping action... those pads were the biggest rip off of my life...

Anyway, ya, stop squeak=anti-squeak blue goo. Goes between the pads and the pistons. If you have shims, hit some between the shim and the backing plate of the pad.
