Rear Wheel Cylinder Piston (UG3689)
- Rolls-Royce Silver Cloud II & III
- Bentley S2 & S3
This piston is from the brakes section in the Rolls-Royce & Bentley parts catalogue for models built between 1956 to 1965.
Given that the master cylinder will wear through normal use and can become corroded over time, it's essential to replace it in order to avoid the risk of brake failure.
A vital part of your car's braking system, the master cylinder converts the pressure created by your foot pressing down on the brake pedal into hydraulic pressure, which builds up as brake fluid becomes trapped. This hydraulic pressure sets the whole braking mechanism into action, ending with the wheel cylinders demobilising the wheels.
The master cylinder is a complicated piece of machinery, itself having a number of components. These include the housing, bore, brake fluid reservoir, fluid level sensor, piston(s), rubber cap, return spring and, in a manual car, rubber boot. Hydraulic pressure is instigated when the spring, cup and pistons slide in the cylinder bore.
