NOTE:

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

WARNING:

Brake fluid is poisonous. NEVER siphon brake fluid with your mouth!
