With Mark II ABS System

All brake fluid deteriorates after a time due to oxidation and absorption of water.
This process lowers its boiling point and makes it more likely to vaporize during prolonged or repeated heavy braking, with brake failure as a result.
Brake fluid must therefore be changed at regular intervals.

Important:
- It is essential to change all the brake fluid as the brake system could otherwise malfunction.
- The total amount of brake fluid in the brake system is about 1.2 liters.
- A brake system bleeder unit can be used for the front wheel brake circuits.

1. Suck the brake fluid out of the fluid reservoir.
2. Fill up with brake fluid, DOT 4 specification.
3. Connect a length of transparent plastic tubing to the bleed nipple on the righthand front wheel brake caliper.
- Place the other end of the tubing in a suitable receptacle, such as a 1 litre measuring flask.
4. Get a helper to depress the brake pedal at the same time as you open the bleed nipple.
- Close the nipple when the brake pedal is fully depressed and then tell the helper to release the pedal.
- Repeat this procedure until about 0.5 liters of brake fluid has been sucked out.
- To drain the other brake circuit for the left-hand front wheel, repeat points 3 and 4 (but drain off about 0.1 liters of brake fluid).





5. Connect a length of transparent plastic tubing to the bleed nipple on the rear wheel's brake caliper (either rear wheel).
- Place the other end of the tubing in a suitable receptacle.
6. Get a helper to switch on the ignition and depress the brake pedal.

WARNING
- The high-pressure pump's electric motor should not be run for more than 2 minutes at a time.
- It should then be allowed to cool down for 10 minutes.

7. Open the nipple until about 0.1 liters of brake fluid has been drained off.
- To drain the same brake circuit for the other rear wheel: repeat points 5, 6 and 7.
8. Top up with brake fluid to the MAX mark on the brake fluid reservoir.
