TRW Rear Brake Pad Set GDB3421

A brake pad in a car is an essential component of the braking system. The brake pad is a flat rectangular or curved-shaped block that is made up of friction materials. Each wheel in a car has a brake pad that is connected to the brake caliper. When a driver applies the brake, hydraulic fluid flows into the brake caliper. The hydraulic pressure forces the brake pad against the brake rotor, which creates friction and decreases the speed of the car. The friction between the brake pad and rotor depends on the hardness and quality of the friction material used in the brake pad. A good quality brake pad is essential to maintain the braking performance of a car, especially in emergency stopping situations.

The brake pad may wear out over time due to the constant friction it creates with the rotor. The longevity of a brake pad can vary depending on the driving habits of the driver. A driver who drives in stop-and-go traffic or uses the brake pedal frequently may need to replace the brake pad more often than someone who mainly drives on the highway. It is important to check the condition of the brake pad regularly and replace it when necessary to ensure the safety of the driver and passengers. Modern cars may have a brake pad wear sensor that will give an indication on the dashboard when the brake pad requires replacement.
