BRAKES STARTING TO LOCK UP
My car has 100000 miles.
My car has an automatic transmission.
A few different things can make the brakes stick or lock up as you describe. The master cylinder may be causing this if it has not been properly bled. If you loosen the lines to the master cylinder and they free up, this is where your problem stems from. In other cases, the problem may be in the brake lines cause the pressure to continue to maintain in the caliper resulting in them sticking as well. Try cracking the bleeder valve to see if this frees them up. If this does not free them up, you may have a caliper that could have a damaged piston that may be causing them to stick. I would recommend having an expert from YourMechanic come to your location to diagnose your braking system.
