- Secure the mounting flange of the brake master cylinder (2) in a bench vice (3).
- Remove the master cylinder reservoir cap (1).
- Install suitable fittings to the master cylinder ports (5) that match the type of flare seat required and also provide for hose attachment.
- Install transparent hoses (1) to the fittings installed to the master cylinder ports (5).
- Fill the master cylinder reservoir (2) to the maximum fill level.
- Depress and release the primary piston (3).
- Continue to depress and release the primary piston (3) until fluid flows freely from the ports with no evidence of air bubbles.
- Remove the fittings installed to the master cylinder ports (5) and transparent hoses (1).
- Install the master cylinder reservoir cap.
- Remove the master cylinder from the vice.
Warning: Refer to Brake Fluid Warning in the Preface section.
Warning: Refer to Brake Fluid Irritant Warning in the Preface section.
Caution: Refer to Adding Fluid to the Brake System Caution in the Preface section.
Caution: Refer to Brake Fluid Effects on Paint and Electrical Components Caution in the Preface section.
Note: The rear of the primary piston (4) must be accessible.
Route the hoses into the master cylinder reservoir (2).
Note: Brake fluid from a clean, sealed brake fluid container must be used when topping up the brake fluid level.
Note: Make sure that the ends of the transparent hoses (1) running into the master cylinder reservoir (2) are fully submerged in the brake fluid.
Note: As air is bled from the primary and secondary pistons, the effort required to depress the primary piston (3) will increase and the amount of travel will decrease.
Note: Use a suitable smooth, round-ended tool to depress and release the primary piston (3) as far as it will travel. Observe the flow of fluid coming from the ports.
Wrap the master cylinder with a clean shop cloth to prevent brake fluid spills.
