TRW Brake Booster PSA235

A brake booster is an essential component of a car's braking system. It works in conjunction with the brake pedal to assist in the application of force to the brakes, making it easier for the driver to stop or slow down the vehicle. The brake booster utilizes a vacuum system or hydraulic pressure to amplify the force applied by the driver, resulting in enhanced braking performance.

When the driver presses the brake pedal, the brake booster senses this movement and creates additional pressure that is transferred to the master cylinder. This increased pressure is then transmitted to the brake calipers or wheel cylinders, causing the brake pads or shoes to make firm contact with the rotors or drums. As a result, the vehicle decelerates or comes to a stop more effectively, making the braking process smoother and more efficient. The brake booster is a critical safety feature that allows drivers to exert less physical effort while ensuring reliable and responsive braking, particularly in emergency situations.
