Trouble with brake locking up

It sounds like you have a brake booster rod that is adjusted too far out, please remove the master and wind it in about a 1/8 of an inch. It also can be that you have a brake hose twisted or you have a bad brake hose, See which tire is locking and then replace that hose.

Hi Chris F. Please start a new question specific to your vehicle, and be sure to list the engine size and mileage. Also include any relevant history that led up to this.

This was a private conversation between two people. As such, none of the other experts are going to see your addition or have a chance to reply. That won't get you the help you need. It also helps with cataloging these questions for other people researching the same problem. A 2009 model is not the same as a 2000 model.

The next thing to consider is brake fluid contaminated with a petroleum product. That will cause rubber parts to swell including the rubber lip seals in the master cylinder. When they grow past the fluid return ports, those are blocked and the brake fluid can't return back from the brakes. To identify that, check if the rubber bladder seal under the reservoir cap is blown up and mushy. If you see that, when the brakes are locked up, loosen the steel line nuts at the master cylinder. If doing that does not let the brakes release, you'll need to open the system at other places to figure out where the pressurized brake fluid is being trapped.
