2007 Sierra 1500 Classic 160kmiles This topic seems to be somewhat covered but I’m at my wits end and reaching out to internet strangers I screwed up and accidentally topped off my master cylinder with the wrong fluid. Ruined everything and the front calipers would begin to drag after just a few miles. flushed 32oz of fluid through the system then replaced the master cylinder and booster. I bench bled the master cylinder. Fronts continued to drag. Then replaced the brake hoses and calipers, bled, and the dragging brakes continued. Then replaced the ABS module, had the brakes power bled and the problem continues. Is there anything left to change, or something I’m not thinking of, or could it be that I didn’t clear all the bad fluid? Every bleeder seemed to be pumping clear fluid. interesting to note, I cannot recreate the calipers dragging in the driveway. I can pump the brakes, drive in reverse and brake, pull forward and brake and the dragging will not occur, I only happens when I’m out driving for a cpl miles at 45-50mph the problem presents itself much quicker the warmer it is outside.

brakes Dragging/locking/grinding brakes
Toolmaker1 posted a topic in 1999-2013 Silverado & Sierra 1500
Hey folks, first time posting here and maybe it’s a common thing. I’ve searched google and YouTube for days, replaced parts, and done the troubleshooting I know to do. So here it is, bear in mind, im no auto mechanic. I’m a jet mechanic/toolmaker. Lol my front pass brake locked up Friday, and the abs/parking brake light has been on since the dealer I got the truck from replaced the parking brake cable. I don’t hear a roaring, so I don’t feel like it’s a hub, but I do have some bouncing on the front end which leads me to think it may be an axel, which I still have to get looked at. parking brake and abs lights come on after a few seconds of driving, I hear brakes grinding, and I just replaced both front rotors, pads, and passenger caliper and abs sensor after it locked up; since it melted the abs sensor cable. brakes are bled properly and working, but they aren’t fully releasing. I’ve checked fluid, it’s not overfilled. Driver hub was previously replaced but not passenger for some reason. I considered ordering a hub for the passenger side just for that. Rotors are 305mm and the pads I installed are ceramic from brake best. Yes, the rotors get hot after a short drive, like too hot to touch. I’d rather not have these things lock up on me again. The only thing left I know to check are the piston in the master cylinder, or the passenger hub. Any ideas? If I’ve missed good reference material or prior posts please feel free to comment with a link and a nice “check here dumbass.” Lol thanks in advance.
