A brake booster, also known as a ‘brake servo’ or ‘vacuum booster’, does exactly as the name suggests, it helps to ‘boost’ the performance of the brakes.

Can a master cylinder be repaired? It is common for piston and valve seals inside the brake master cylinder to leak after years of service. Still, you can fix the problem by installing new seals, sold at most auto parts stores as minor brake master cylinder kits.
Furthermore, Why do master cylinders fail?
There are rubber seals on the master cylinder that wear out and break down with continuous use. When that happens, the brake fluid will get contaminated. When the seals are damaged, the cylinder will not hold fluid or brake pressure effectively, and this will cause the pedal to be mushy.
