Last week I upgraded my brakes with Carnewal's Big Red brake package and a new set of SS braided lines from FDM. I know the brakes are over-kill but, 1) it was time for pads and rotors, and 2) The Big Red upgrade is just like the car......plain and simple, I wanted it.

The process was fairly easy, all brake lines came loose with little effort and the Motive Power Bleeder was a big help. I knew everything went way too well. After two cycles of bleeding the brakes (just to make sure all the air was out) I took the car for a short drive. The pedal was a little on the soft side, and the stopping power was a little weak. The next day I took the car out and made a series of hard stops to put some heat into the pads and rotors. Problem solved, hard pedal and nose-to-windshield stopping.

On the way home, I noticed a "scrubbing" sound (all rotors turned freely before mounting the wheels). Once in the garage, I felt all four rotors and calipers and did not notice any substancial temperature difference; however, the right rear did have excessive brake dust on the rotor, caliper and wheel.

I think one of the caliper pistons is not freely moving, but find that odd for a new caliper. Before I start pulling it apart, any input as to what may be the culprit and solutions would be appreciated.

Thanks!

Jeff,
I would jack the car up, undo the caliper, and then fully compress both sets of pistons back into the caliper. Slip it back on, hit the brake pedal a few times and repeat.

Then I'd perform a thorough bleed on all 8 bleed nipples.

No technical reason, other than - this is the first thing that came to mind.

Andreas,
Thanks for the input, I'll go through your process this weekend. Hopefully that will correct the issue.
