Master Brake Cylinder Replacement
The master cylinder generates pressure in the brake circuits when the pedal is pressed. Worn seals can allow internal fluid bypass without a visible external leak. Before replacement, we check other causes of altered pedal travel, including air in the system and leaking lines. Installation requires clean connections and correct air removal. After assembly, we assess pressure retention, fluid level and pedal behaviour rather than relying solely on the absence of wet connections.
Symptoms
- The pedal gradually sinks under steady pressure.
- Fluid leakage around the master cylinder.
What's included
- Verify the diagnosis requiring master cylinder replacement.
- Remove the unit and inspect the reservoir and connections.
- Install the cylinder and bleed it using the specified procedure.
- Check for leaks and assess pedal holding under load.
