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

TIP:

Press the brake pedal slowly to prevent bubbles from building up.

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

-- Open the bleeder screw with bleeder bottle hose connected, until the pressure is reduced (pedal drops).

-- Hold the pedal in the 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 under consideration of brake pad wear up to the "MAX" mark and screw on the fuel cap.

Do not add brake fluid above the "MAX" mark otherwise it will leak out of 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.

CAUTION:

Faulty brakes increase the risk of an accident.

- Make sure the brakes are working correctly before driving the vehicle for the first time.
