Front Brake Squeal Sound

Some 2020 XT4 models may have a brake squeal sound at low speeds. (Fig. 17) The front brake pads on some models may be susceptible to producing brake squeal.

Confirm the brake squeal is coming from the front brake pads. If verified, replace the front brake pads (Fig. 18) with a new design brake pad. Refer to Front Disc Brake Pads Replacement in the appropriate Service Information.

TIP: Disconnect the battery to prevent the brake master cylinder from pressurizing the hydraulic system during its automated self-diagnostic tests that can occur when a door is opened or the key transmitter is activated.

The disc brake pads are adhered to the caliper piston using an adhesive patch and must be separated. Do not insert a pry tool through the bridge window to pry against the piston face, which can damage the brake caliper piston. Loosen the inner brake pad by twisting a screwdriver between the inner brake pad and the brake caliper. Do not allow the screwdriver to touch the brake caliper guide pin seal.

Refer to Bulletin #20-NA-002 for additional information and part numbers.

    OK WE WILL TELL OUR CUSTOMER’S THAT THERE IS SERVICE BULLETIN #20-NA-002 FOR A NEW DESIGN BRAKE PAD , BUT SINCE THE CAR HAS 10,000 MILES ON BRAKE PADS ARE NOT COVERED.

  3. Dealerships should follow the New Vehicle Limited Warranty. Brake pads are covered up to 7,500 miles. This issue is usually present within a few thousand miles.
