Acura Tech Tip: Rear Brake Clunking Noise

Acura Tech Tip: Rear Brake Clunking Noise

The rear brake calipers clunk when you first apply the brakes after changing the direction of the vehicle. This is caused because the outer shims on the rear brake pads do not allow the pads to slide easily when you press the brake pedal. This causes the outer pad to hit hard during a change of direction, resulting in a clunk.

The rear brake calipers clunk when you first apply the brakes after changing the direction of the vehicle.

Applicable Vehicles:
• 2001-’03 MDX, all; and
• 2004 MDX, from VIN 2HNYD1…4H500001 through 2HNYD1…4H514801.

Probable Cause:
The outer shims on the rear brake pads do not allow the pads to slide easily when you press the brake pedal. This causes the outer pad to hit hard during a change of direction, resulting in a clunk.

Corrective Action:
Replace the rear brake pad shims.

Note: Brake pad replacement and disc resurfacing is not needed to get rid of the clunk.
