The brake servo is a system which increases the driver's foot pressure on the brake pedal. Using a brake servo doesn't improve braking performance; it simply helps with the amount of force needed for brake operation. The four-piston front brake callipers and a brake servo system providing enhanced pedal response are just as critical for the car's performance.
The brake servo uses engine vacuum to increase the pressure you apply on the brake pedal. Brake servo is a metal canister holding a smart valve and a diaphragm. A rod going through the middle of the canister attaches on one side to the piston of the master cylinder and on the other to the pedal.
By feeding brake fluid into the braking system, brake servo transforms the pressure on the brake pedal to hydraulic pressure and adjusts that according to the mechanical force. Here are few signs if brake servo develops a fault.
The Brake servo is prone to deterioration, especially if the adjacent brake master cylinder has leaks.
