BLEEDING THE BRAKES For Master Cylinder Replacement
1. Add oil after master cylinder replacement.
2. Run the engine and depress the brake pedal several times to build pressure and then keep the pedal fully depressed.
3. Loosen the screws of primary and secondary pipe at the master cylinder outlets to bleed air.
4. Repeat above step No.3 several times until there are no more air bubbles.
5. Bleed air in the system at the hydraulic unit outlet pipe and wheel if pressure building is not enough by depressing the pedal only after above air bleeding.
For Caliper and Brake Hose Replacement
1. Check the oil level from the oil reservoir and refill if necessary.
2. Run the engine and depress the pedal several times to build pressure and then keep the pedal fully depressed.
3. Connect a vinyl tube to the caliper breather and prepare a container to coentain brake oil.
4. Loosen the breather screw until there are no more bubbles.
5. Bleed air in the system at four (4) wheels in order as shown in right figure if pressure building is not enough by depressing the pedal after above air bleeding.
