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.
