Brakes are sticking and locking up truck is being held back

No I have drum brakes in the rear.

Truck listed above is the new body model. So my mechanics helper accidentally put about an ounce of power steering fluid in my brake reservoir. I didn't have any issues right away but maybe a month or two later I started having problems with the front brakes locking up. The pedal starts to get stiff and you can feel the resistance building up until the truck will stop itself once you let off the brakes. Pretty soon the truck will not be drivable or movable. The only way to get it moving again is to crack the bleeder screw on either side of the front calipers. I immediately had my buddy's shop replace the passenger front caliper (old one had a ton of tar and was looking pretty rough) and both front brake lines. I also had him reset the ABS and bled the system. Left his shop and 10 miles or less back to the brakes locking up. He instructed me to remove both ABS fuses and see if that stopped the issue. It has not. I am at a loss and my buddy's shop is too swamped to get me back in anytime soon. I am a marine mechanic and am confident I can sort this out with some help once I get pointed in the right direction. Any insight would be greatly appreciated. (Have Haynes Shop Manual on this truck as well) Thanks 2CarPros in advance!

So the fluid has been filled and bleed a few times before the front brake lines were replaced. I feel confident saying that the power steering fluid would have been flushed out prior to the changing of the brakes lines. I understand that this is a split system and also hydro boost assisted. One other piece of info I forgot to add is that the brakes lock up much faster if the truck sits and idles as opposed to driving. Wouldn't the rear brakes also have been locking up from the power steering fluid put into the master cylinder? I know this is a whole can of worms and if I have to rebuild the entire braking system I guess that's just the route I will have to go. I am doing my due diligence and research and will get this solved one way or another. Just hoping I can purchase rebuild kits for some of these parts and not get sucked into having to buying a ton of high priced parts.

You can drive about 20 feet when the truck stops without touching brakes. When I say stop I mean almost puts you through the windshield. After it sits a while it will drive about 10-20 feet before it does I again. You can hear a clunk from the back end. Back tires will spin but front end won't move if you gun it without touching brakes.

I have a 2006 Chevy Silverado LS, T engine and my front brakes locked up on both sides. I changed the calipers, brakes and high pressure lines that run from the caliper up. The brakes are still locked up. Do you have any suggestions as to what it might be? The ABS light on the dash is not lit, nor is the brake light. I know that they do work because I unplugged one of the ABS lines and the dashboard lit up. I have also tried bleeding the brake lines. If I remove the caliper and push the piston back in, after reassembling, hitting the brake pedal again, the pistons will not retract.

Both fronts are locked up. Also, I have already checked the rubber hoses.

Brakes problem V8 Two Wheel Drive Automatic 85000 miles

I have a 2005 Chevy Silverado that I recently purchased. The problem that I have is when I first back out of the driveway in the mornings. When I go to put the truck in drive it will not go because the brakes are locked up. If I put the truck in reverse again and then back in drive it will go. As I go out the gravel drive and press the brakes both back tires will lock up and slide. This only happens in the morning when I leave for work. I can not see any brake fluid leaking from the inside of the wheels like a brake cylinder leaking. Does any one have any suggestions. Thanks in advance for your help

Front brakes will lock up after car drives a while, calipers will not release. They sometimes do, sometimes do not. Causes the car to overheat because the rpm's rev up as the brakes are engaging. Replaced pads, rotors, calipers, master cylinder, brake booster and installed AcDelco hoses. Same issue occurs. I have had to replace pads, rotors and calipers four times in a year and a half. Removed ABS fuse, same issue. I am baffled.

Ken, Thank you for the information. How do I adjust the booster rod to not extend out too far? Thank you

The truck drives just fine if I am only going straight. I guess the brake pedal could be a little firmer, but otherwise it brakes fine. My problem is when I turn. When I am reversing out of my parking space and the wheel is turned, the front brakes lock up. When I turn a corner or drive through an intersection and turn the wheel the front brakes will lock up. It does it when I turn both ways. From all of the blogs I have read I am leaning towards replacing the power brake booster, but I could really use some advice from someone who has experienced or heard of this problem.

Thank you.
