Subject:
BRAKE PAD CLICKING NOISE


A clicking type noise may be noticed when first applying the brakes after changing vehicle travel direction (Drive/Forward to Reverse, Reverse to Drive/Forward). This is a normal noise caused by the required brake pad to caliper clearances. When the direction of travel is changed, the brake pads may "shift" towards the new direction of travel. When the brake pad contacts the caliper, a clicking noise may be heard.

To minimize this clicking noise, a disc brake caliper grease has been made available for use during brake service/maintenance operations. Under normal usage conditions this grease should be effective for a period of 6 months to 1 year.
