Brakes, FS III Overview

Brakes, FS III Overview

• To siphon off brake fluid from the brake fluid reservoir, use the brake filler/bleeder unit (VAS 5234).

• Before removing a brake caliper or disconnecting a brake hose from a brake caliper, install the brake pedal actuator (V.A.G 1869/2) , to prevent the brake fluid reservoir from draining.


After installing brake pads, depress brake pedal several times firmly to properly seat brake pads in their normal operating position.

• Install complete repair kit

• After replacing brake pads, depress brake pedal several times firmly to properly seat brake pads in their normal operating position.

• When siphoning brake fluid, always use a bleeder bottle that is used exclusively for brake fluid. Brake fluid is poisonous. NEVER siphon brake fluid with your mouth!
