I just finally got my new pads and stainless lines installed on the car. I'm still working to get a little air out of the lines but it's definitely better than it was the first time around.

I'm running PMU HC+800 pads and GTM Challenge stainless lines. The car was washed before going to a car meet this weekend so everything was spotless...not a spec of brake dust on the wheels. I got home later in the day and noticed that it seemed the rear wheels had more dust on them than the fronts. I know this is not typical. I'm wondering if the rear pads are dragging at all but how do I check? When I installed the pads the pistons in the caliper spun in easily so I'm pretty sure it's not a frozen caliper. I will say that the pads fit really tight in the pad guides. Is it possible this is what's making them hang up a little bit?

I also did not pull and re-grease the pins but I checked each one before doing any install and them seemed to move freely as is.

 

Easiest way I'd say is jack up one side of the car (or the rear) and spin the wheels by hand. If it's dragging you'll feel it. You could have someone step on the brakes and release it as well w/ the rear in the air and try to spin them again. If there's resistance after releasing the brake then you have a problem.

 

There will be resistance in the rear becaus it's bolted to the differential. The rear wheels won't move as freely as the front do. Jack the rear wheels and try to the wheel about a half inch, it should move freely and after it catches the differential and takes some force to move.
