Front Brake Pads (appearance will vary) When servicing or replacing brake pads it is advised to wear a breathing mask over your nose and mouth to avoid inhaling brake dust particles. It is also advisable to wear gloves to avoid skin irritation. These dust particles have been known to cause health problems when exposed to them for an extended amount of time. When replacing brake pad always match the old brake pads to the new brake pads. The backing plate of the brake pad should be identical to the old brake pads, except for the missing brake pad composite material. Some brake pads are fitted with anti rattle clips. These clips are design to allow the brake pads to move freely within the caliper mount.
