DRUM BRAKES
Description
In a drum brake, the pressurized fluid from the master cylinder actuates pistons in the wheel cylinder. The pistons force the drum shoe and lining friction material against the drum surface generating a braking torque force. This force is then reacted through the drum backing plate and suspension, slowing the wheel and the vehicle.
Technology/ Benefits
Drum brakes are a good alternative to caliper/disc systems when cost is a priority to the OEM. With proper sizing and system tuning, drum brakes can perform well in many applications. BWIGroup utilizes our knowledge to optimize brake feel and noise performance.
Applications
Industry competitive leading-trailing designs are available in a full portfolio to support small car to full size truck and SUV applications. BWIGroup also provides drum-in-hat parking brakes as well as wheel cylinders.
