What Causes the Brake Noise in Jaguar XEL?
2 Answers
Possible reasons include new brake discs and pads that need to be worn in, which can cause noise during braking. The noise may manifest as vibration friction or a sharp hissing sound. In dusty or sandy weather conditions: sand or dust particles may enter between the discs and pads, leading to a hissing brake noise. Brake Wear: Severe wear of the brake pads may cause the caliper to reach its maximum limit and fail to retract. This is common in older vehicles—replace the brake pads. High Brake Cable Resistance: Excessive resistance in the brake cable, often due to internal rust, icing, oil contamination, or dust accumulation. It is recommended to replace the brake cable. Rear Brake Caliper Wear: Severe wear of the rear brake caliper. Common in older vehicles that have had brake pads replaced, where the caliper's working surface is heavily worn and stuck. Transmission Mechanism Wear: Issues such as improper brake cable routing, aging or deformed cable sheathing, etc. Specific models require individual analysis. If unable to resolve the issue independently, consult a professional mechanic for assistance.
I've driven quite a few cars, including the Jaguar XEL, and brake squealing is actually quite common. There could be several reasons: uneven wear or hard spots on the brake pads, where prolonged use makes the pad surface uneven, causing squeaking when braking; rust on the brake discs, especially after rain or in humid weather, where the disc surface gets rusty—a few light brakes can remove the rust; newly replaced brake pads need a break-in period, and some noise in the first few hundred kilometers is normal; sand or dust getting stuck in the brake components, which often happens after driving on sandy roads; or the caliper not retracting properly, causing the pad to drag on the disc. I recommend that owners first visually check the thickness of the brake pads—if it's below 3mm, they should be replaced. Listen to the type of noise: a high-pitched squeal usually indicates pad issues, while a grinding sound might point to disc or caliper problems. Safety-wise, even though brake noise seems minor, it shouldn't be ignored. Have a technician check it during regular maintenance, and after washing the car, take a short drive with light braking to remove moisture and prevent rust.
