Brake Pads, Removing And Installing, Ceramic Brakes 1LW: Removing

NOTE:

brake caliper must not be removed in order to remove brake pads.

Label the brake pads when removing if they are going to be used again. Install in the same position, otherwise the braking effect will be uneven.

Check the ceramic brake rotors for damage and wear each time the brake pads are changed.

NOTE:

Before removing old brake pads, press brake piston into cylinder using resetting tool. Before pushing back the piston, extract some of the brake fluid out of the brake fluid reservoir using a bleeder bottle. Otherwise fluid will overflow and cause damage if the reservoir was topped off during repair work.

WARNING:

Brake fluid is poisonous, and must never be siphoned by mouth under any circumstances.
