NOTE:

It must be bled on each bleeder screw. Bleed the brake caliper with two bleed screws first on the inner screw.

-- Build pressure up in brake system by pumping brake pedal.

NOTE:

Slowly depress the brake pedal to prevent the formation of bubbles.

-- As soon as pressure is built up, hold brake pedal in depressed position.

-- Leave the bleed screw open, with container hose connected, until brake fluid flows out clear and free of air bubbles.

-- Hold pedal in completely depressed position and close the bleed screw.

-- Release brake pedal and wait approximately two seconds so that brake fluid can flow out of the brake fluid reservoir.

-- Repeat the procedure until the brake fluid flows out clear and without bubbles.

-- Tighten the bleed screw, remove the bleeder hose and place the protective cap on the bleed screw.

-- Repeat the bleeding procedure in the specified sequence for the remaining brake calipers.

-- Fill the brake fluid reservoir with brake fluid up to the "max" mark.

-- Screw down the reservoir.

-- Start the engine and check the brake pedal travel and pressure.

-- If the pedal travel is too long, check the brake system for leaks or repeat the bleeding procedure.
