i just installed the 13" front brake drilled kit with 4-piston caliper on saturday. I know that i still have to re-bleed the lines one more time because of mushy pedal on the first pump. after that it starts to get harder. now when i am driving around in the streets, the brakes squeak. will this go away? anything i can do to stop this sound?...I have the axxis pads that i got from Avalon Racing.

any info would be greatly appreciated..

 

Did you thoroughly clean the rotors as instructed? Did they begin to rust almost immediately? Did you bed the new pads? YOU ABSOLUTELY, POSITIVELY have to do this. Bedding in new pads.

Also, follow the instructions to unbolt the caliper and hold it vertical for bleeding. Keep the caliper on the rotor by holding it in place during the bleeding. DO NOT let it come off of the rotor! Regardless of the instructions that it *may* be necessary, IT IS NECESSARY. I called StopTech and they are revising the instructions to inform all new buyers as such.

 

All peerformance bake kits, be it a big brake kit or not has a couple hundred mile +/- break in period .This is where the pads and rotors are starting to seat. There will be a littlwe noise for a while then it goes way. Also big brake kits needs to come up to temperature before they are at optimum performance.

I have tried 2 sets of pads, both properly bedded and both still squeak at slow speeds when stopping at a light or something.

I do not think that you can do much to fix that. It definitely bothers me but it is not THAT bad! Maybe some sort of rubberized shim that goes between the pad and caliper.

My old 300 had a rubberrized shim in them and made no brake noise whatsoever. Without them (I forgot to reinstall them once) they squeaked like an SOB.

The pads on the stoptech brakes are the same size/shape as the factory 911 brakes (or so I was told, please correct me if I am wrong!) so maybe a porshe service dept. may have something to help? (just a shot!)

If you find a fix please post it of even better PM me! Good luck.

 

there has to be a way to get rid of that sound, i will use them for a couple hundred miles then see what i can do. is there another brake pad to use?.....when i had my wilwood kit on my acura..i originally had the wrong ones, then i got the right ones..sound went away!!

 

You can totally eliminate that sound by bedding in the pads and rotors properly, assuming you have a set of street pads installed. I'm willing to bet money that you weren't agressive enough when bedding them in. Given that you've still got a spongy pedal from not bleeding all the air out, I'm not surprised that you didn't get on the brakes hard enough to do it. Follow my instructions here AFTER you bleed the brakes again: http://www.zeckhausen.com/bedding_in_brakes.htm

First thing is to get that air out by tipping the caliper forward while bleeding. When bleeding the passenger side caliper, turn the wheel to the right so that you have enough slack in the brake line to tilt the caliper all the way forward. You can slide the line through that metal bracket that bolted to the stud left over from the stock line. You absolutely must do the caliper tilt on your first bleed. Subsequent bleeds won't require this. StopTech has the master Adobe Illustrator file for the installation manual, so they are going to change the wording to make this mandatory rather than a suggestion.

 

WHAT HE SAID!!!

I was probably the 1st person (at least one of) to have StopTechs installed! I bedded em' THOROUGHLY after install (I did have to re-bleed) but I have not had ANY issues, and they STOP ON A DIME!

 

You reposted EXACTLY what I said in the second post. I even referenced your bed-in procedure.

For the record, I have ZERO noise from my brakes. My second bed-in was HARSH and perfectly deposited pad material across the rotor. The only minor problem I have is being too easy on the brakes in traffic. I now do a few heavy stops right before I get home in the evenings to keep the pad material deposits even across the rotor.

 

Then it MUST be true! We've seen it on the Internet and we have corroboration.
