Brake Master Cylinder: Description and Operation

1 Tandem Master Cylinder
2 Brake Booster
3 Pedal Box
4 Fluid Level Indicator Switch

The tandem brake master cylinder is mounted, together with the vacuum booster, in the forward bulkhead extension within the engine compartment. The brake operating pedal is housed with the accelerator pedal in a plastic pedal box.

The brake fluid reservoir has a fluid level indicator switch installed, which opens when the fluid level is low, causing the fluid level warning lamp to illuminate.

The applied brake pedal force is increased by the booster which activates the intermediate piston of the tandem master cylinder. As the piston moves, fluid under pressure is displaced from the master cylinder into the brake lines and caliper assemblies to apply the brakes.
