What would cause the left front and right rear brakes to lock up and stay engaged? I have changed the master cylinder, brake booster, brake hoses, and both calipers. Also bled air from complete system. Could or would it be a failing or failed and pump/module?
Hi, this is Bo, an auto expert on RepairPal's Car Genius team!
If your left front and right rear brakes are staying engaged after replacing all those parts, the issue could indeed lie with the ABS pump or module. A malfunctioning ABS unit can cause uneven pressure, keeping brakes locked even when they should release. Since the master cylinder and calipers are new, it points more toward the ABS system not properly releasing hydraulic pressure. Before throwing parts at it, though, you might want to have the ABS system scanned for fault codes to confirm.
