Cadillac XLR rear brakes lock up while driving consistently on Cadillac XLR

Some Cadillac XLR owners report experiencing consistent rear brake lock-up while driving, which may be attributed to several factors. These issues can stem from a failed wheel bearing or, in rare cases, a malfunctioning brake caliper. Additionally, improper brake fluid, overheated brake components, and excessively worn brake pads, calipers, rotors, drums, shoes, and wheel cylinders can contribute to the problem. Owners should also be aware that brake lock-up can occur when the friction of the brakes exceeds the tire's traction, although front brakes are typically more susceptible to this issue. Furthermore, if the Traction Control System (StabiliTRAC) activates, it may signal that the Electronic Brake Control Module is applying brakes to specific wheels, potentially rendering the vehicle undriveable. It is recommended that owners seek a professional inspection to accurately diagnose and resolve the rear brake lock-up issue in their Cadillac XLR.
