its always worse when new rotors and/or pads go on. The surfaces haven't had time to bond together yet so i'd say the braking during the break in period was like 35% of what it should be normally. It was honestly kinda dangerous, i had to brake WAY early when coming to a stop.
Has anyone ever had a proportioning valve get clogged? I've never heard of this being a problem in any brake system, until a few days ago i'd never even heard of the part. However, it does seem to describe some of my problems. During one of my visits to my mechanic, I drove it around for a while till the brakes got hot, then took it to them. They took a temperature gun to my rotor/brakes through the wheel, and my front left brakes were at like 470 degrees and the front right side was only like 240. My front left brake pads always wear out faster. That much is consistent.
