In this video, sponsored by Napa, Andrew Marquel, an automotive expert, shares vital signs to watch for when diagnosing brake caliper issues. The first sign is uneven brake pads, indicating problems with the caliper’s ability to distribute force equally. Next, a damaged dust boot allows water and debris to corrode the piston and bore, leading to potential failure.
Additionally, if you encounter a seized caliper guide pin, it suggests corrosion that requires caliper replacement. While not essential, Marquel recommends replacing the brake hose when servicing the caliper, as heat buildup may have damaged it. Remember, a properly functioning brake caliper is crucial for safe vehicle operation. As an added tip, Marquel mentions calipers with protective coatings that enhance their appearance and protect against rust.
