Just installed my 6 piston Wilwood kit, and took it out for a spin. I had a few questions regarding this. Are the pads supposed the be touching the rotor even when not braking until they are "broken in"? I can hear them rubbing at low speeds, and even worse when stopping. Also, I have to push the pedal in really far until I feel the pads bite. Could this be a brake bleeding issue? The car in general feels "shaky", and I am nervous about it. I was not sure what kind of break in period there was. I have been driving slow and gently braking. Anyone with advice or help? Thanks!!

 

Looks like you need to bleed the brakes so you can get better brake feel. The other issues I dont know about.

 

Just ordered the Go Fast Lab break bleeder. Hope that will resolve the pedal feel. Anyone else on the other issues?

 

Don't you have to properley "bed" in the pads? Which pads did you install or did it only come with one set?

I believe my 4pot touched all the time but very slightly (no pressure, as in you could still turn the rotor by hand)

As for the pedal feel, it should feel stiff so it's most likely a poor bleed job.

 

I am not sure what you mean by "bed in the pads". I installed them as shown in the write up in the group buy. Right now, it seems that not all of the pad is touching the rotor. Will this change until it wears down and evens out? I can turn the wheel by hand, but it is a tight fit with the shims installed. Any other advice?

Thanks. That is good info. I guess I am unfamiliar with the experience of driving with a new brake kit, let alone new brake pads. I don't know what to expect, and I was hoping others could chime in with what they have experienced.

 

Bedding in pads is more for track use. Several hundred miles of normal daily driving will eventually "unbed" the pads and you'll have to do it again anyways.

 

It's normal for pads to be touching the rotors at all times with any disc brake setup, stock or otherwise. If you hear odd metal on metal noises that you didn't hear with the stock pads then it's likely due to a more aggressive (read: abrasive) compound for the pads (assuming you did the install correctly).

As far as pedal feel goes, make sure the system is bled properly or you will get that mushy feel you describe. It can also be due to other things though, like too much piston area compared to stock although that would be up to the engineers of the caliper to figure out.

Your power bleeder went out today btw.

i have the wilwoods and i know that they have to be bled a certain way. i'm not sure what size discs you got but it mght be your dust shield behind the rotors that's rubbing. the dust shield has a few points that get really close to the disc and on mine they would rub. hope this helps you alittle.
