I decided to bleed my brake fluid today since the fluid was getting old. Started on the driver front, then worked to the back and around, doing the front passenger last.
When I unscrewed the brake bleeder on the first three, everything felt fine. They broke loose and unscrewed with ease. The last one though didn't feel right at all. Once it broke loose, it was harder to unscrew and felt like it was grinding for the first 3 turns. I crossed my fingers, tightened it back up, and went out for a test drive. At 40 mph, started hearing crackling in the front right. Came back and found brake fluid splattered in a line across the inside of the fender. I thought...great, I didn't tighten it enough. I went back and tightened them to check and went out for another drive. Same thing.
Came back home and removed the bleeder screw, and found the tip was grooved badly. Great. Looks like the factory over-tightened this one like crazy. Just my luck.
Biggest concern right now is the amount of brake fluid that got on the inside of the wheel. That better not corrode or I won't be a happy camper.
Not my first time bleeding brakes. The dealer better not give me a hard time replacing the bleeder screw, a $2 part. I was pretty annoyed going to the parts store and discovering that GM changed the screw so they aren't available anywhere.
Going in tomorrow or Tuesday.
