Genuine BOSCH Brake Master Cylinder
Part number B227-114

Master cylinders convert the pressure applied by the driver’s foot and amplified by the brake booster into hydraulic pressure. The cylinder converts this pressure by feeding brake fluid into the braking circuits and controlling this process. The latest generation of Bosch master cylinders (TMC8) not only saves on space, but also helps save fuel thanks to its low weight.

 

PRODUCT BENEFITS FOR MANUFACTURERS 

  • Needs less space for installation
  • Helps to reduce fuel consumption by a weight reduction
  • High brake fluid flow rate even at low temperatures
  • Worldwide standardized manufacturing process guarantees the same quality standards

A brake master cylinder is one of the most crucial components in a car's brake system. It works by converting the force from the brake pedal into hydraulic pressure that pushes the brake fluid into the brake lines, which in turn triggers the brake calipers or wheel cylinders to clamp down on the brake pads or shoes and slow down or stop the wheels' motion. The brake master cylinder usually consists of a cylinder, a piston, and a reservoir that stores brake fluid.

When the driver steps on the brake pedal, a pushrod or booster mechanism will apply pressure to the piston inside the brake master cylinder, causing it to move forward and apply pressure to the brake fluid. The brake fluid will then travel through the brake lines and apply pressure to the brakes, either through a hydraulic disc or drum brake system. A defective brake master cylinder could cause various brake-related problems, from spongy brake pedal feel to a total brake failure, making it essential to check and replace the brake master cylinder regularly as part of the car's maintenance.
