Jaguar XF – Front brake squeal
Fault:
A customer’s 2010 Jaguar XF is suffering with front brake squeal when braking at low speeds, and as the vehicle comes to a stop. We have removed and inspected the brake pads and brake discs, which are all in good condition, but we still can’t find a fault. Have you come across this before?
Fix:
Yes, this fault is known to us and also affects Jaguar S-Type (X200), XJ (X350/358) and XK (X150) models with 326mm front brake discs. The squeal is due to resonance from the front brake caliper anti-rattle spring. Remove the front brake caliper anti-rattle spring and, using the anti-squeal shim kit (available from parts distributors), fit anti-squeal shims to the front brake caliper carrier (see Fig 1). Following this you should then fit an anti-squeal shim to the inside of the caliper anti-rattle spring and refit the front brake caliper anti-rattle spring. Road test the vehicle to confirm the fault has been resolved.
