Brake Issue
I washed my car the other night, including the wheels, and parked the car in the garage as usual. I went to back out today and the car wouldn't budge. I had this issue before on my C7 and my C6 when the rotors rust. The car was not driven before I washed it. The brakes were cool.
I had to actually to a burnout in reverse after trying to rock the car back and forth to free the brakes. The car hunched down and the rear wheels spun, pulling the fronts.
I took the car out for a drive and noticed considerable brake noise, which I associate with the rust wearing off. I had a brake pedal pulse too.
I've driven the car a bit more and done some higher speed braking to clean the rotors. The pedal pulse is pronounced and not dissipating.
What could be my issue? I just returned from a 7500 mile round trip of the U.S. and the brakes were flawless.
Thanks in advance.

Take it out and do some hard stops from high speed. The rotors will clean up.

I have had problems with this before on my C5 but never to the degree you are experiencing. I have a Master Blaster that I use to try to dry the brakes off but I always drive back and forth with the brakes on prior to letting it sit now.
Hope you get this sorted out. Frustrating I am sure. Good luck.

Would try bedding the brake pads and see it resolves the issue. Need about 5 or 6 consecutive hard stops from 60 mph to ~10 mph, don't stop and repeat. Then let them cool off by driving without stopping for ~10 minutes. Does require a place with little traffic to do but I had to do twice to stop squealing, which it did. Bedding procedure for my CarboTech 1521's was similar and just followed the manufacturers recommendations.

They have a problem with some rotors being inferior metal and warping easily. I constantly had a from left rotor warp. They re calibrated the electronic brakes, replaced back rotors ( WTF?), and surfaced rotors while on the car. 5-6 visits and they replaced front rotors. Looks like it worked.
