TRW Brake Booster Genuine OE Quality Replacement. We apologise in advance for any inconvenience caused.A Brake Booster is an enhanced master cylinder setup used to reduce the amount of pedal pressure needed for braking. It employs a booster set up to act with the master cylinder to give higher hydraulic pressure to the brakes and/or lower force applied on the brake pedal through a brake booster pushrod. The brake booster usually uses vacuum from the engine intake to boost the force applied by the pedal on to the master cylinder, or may employ an extra vacuum pump to enable it. Without the engine running the brake pedal feels very hard and ineffective on the braking capability. Apart from this additional booster setup, the braking system is a normal Hydraulic brake system.
