TRW Automotive supplies booster and master cylinder brake actuation systems featuring quality and performance.

The company has developed and supplies the Girvac actuation design, among the world's best-performing and lightest weight actuation systems. These systems utilize the Girvac brake booster, with its unique tie-rod design that allows for efficient absorption of pressure from the booster. This leads to enhanced performance, and enables the booster shell to be much thinner and lighter as the shell does not have to transmit the force through the booster as is the case with many competitive designs.

TRW's booster and master cylinder product portfolio covers a wide range of vehicles, from small cars up to truck and SUV platforms. These systems can offer enhanced packageability and lighter weight, with options such as micro master cylinders and aluminum master cylinders through to heavy-duty master cylinders designed for the durability and variable loading conditions of the light-truck market.
