There are times when I start the vehicle, or manually release the parking brake, that it simply does not release. The brake pedal becomes rock hard at these times, without its normal travel. If the vehicle is reversing, like leaving my garage, it stops like it hit a brick wall when the brake pedal is touched. The rear brakes are simply locked. It stops so abruptly that it has aggravated lower back pain from previous injuries. Iâm afraid of getting stranded in traffic, unable to move the vehicle. It did this on dirt and it was just dragging the rear tires. The only solution I have found is to turn off the engine, wait a few seconds, restart the vehicle, hope. I got, in rapid succession: 1. ANTILOCK BRAKE FAULT !!! 2. HILL DESCENT CONTROL FAULT 3. PRE-COLLISION ASSIST NOT AVAILABLE 4. HILL START ASSIST WARNING The service at Mesquite (Nevada) Ford was totally insufficient. I expected them to find and fix the problem, which obviously lies in the anti-lock/parking brake. I was eager to get the vehicle back and find out what was wrong as Iâve been afraid to use the manual parking brake for fear it will seize up and not release. When I got the vehicle back (which took a long time and a long story as the mechanic went home sick in the middle of the job with COVID) they said, âOh, we reset the error message so everything is fine.â Well, it still locks up, sometimes when I have shut the engine off and sometimes when I tried to manually set the parking brake, w
