What is the brake booster Function?
The brake booster is located between the brake pedal and the master cylinder and functions to multiply the force of the brake pedal further. This increases the pressure on that side of the diaphragm and further pushes the lever along, which pushes the piston in the master cylinder – and the rest is business as usual.
