| Notes on repairs to brake system | ||
Hydraulic brake system assisted by compressed air: empty the reservoirs (1) and renew the brake fluid. First in the rear axle brake circuit. | |||
2 | Remove the cap and connect the bleeding equipment to the opening of the reservoir (1) | Put the bleeding equipment in operation supplied with the respective pressure. | |
3 | Fasten the rod of the ALB regulator (4) at full load | ||
4 | Remove the plug of the cylinder to be bled and install the hose | The hose is used to drain the fluid into an adequate container. | |
Start the process of replacement by the rear wheel hydraulic cylinder or the one that has the pipe of largest diameter. | |||
5 | Start the bleeding | Apply pressure in the system, open the hydraulic cylinder bleeder of the rear wheels (2), at least 45º, and let the brake fluid run out. Open the hydraulic cylinder bleeder of the rear wheels (2) and close it again until no more bubbles exist in the bleeding hose. | |
6 | Renew the brake fluid of the clutch slave cylinder, through the bleeder, through the clutch receiver cylinder bleeder (3) | Open the clutch receiver cylinder bleeder (3) and close it again until no more air bubbles exist in the bleeding hose. | |
7 | Release the ALB regulator rod (4) | ||
8 | De-pressurize and remove the bleeding equipment and the drain hose | Check the reservoir (1) and refill it to the "MAX" level marked on the container. | |
