Brake Master Cylinder - PMK561 TRW

The TRW brand Brake Master Cylinder is used to transform the force from the brake pedal into hydraulic fluid pressure, which will press against the caliper piston. This is possible due to the ability of the brake fluid not to contract under external influences. This unit is located on the roof of the vacuum brake booster, which reduces the pressure on the brake pedal for maximum braking efficiency. Above the cylinder there is a tank filled with brake fluid, which at the right time enters the compartments through the appropriate gaps.
