High Temperature Re-Clamp

After heavy use of the brakes the disc temperatures can be extremely high. At high brake disc temperatures, if the vehicle is stationary and the parking brake is applied, the EPB module automatically re-applies the parking brake as the brake discs cool down. A temperature model in the EPB module software calculates the brake disc temperature from brake application force, the time the brake force is applied and vehicle speed.

High temperature re-clamp occurs at brake disc temperatures of 300 °C (572 °F) and above. Depending on the temperature up to three re-clamps can occur, at varying time intervals, in the 10 minutes following the initial application of the parking brake. To limit the number of re-clamps, the ignition status as well as the current inclination of the vehicle is considered. If the ignition is on, a re-clamp will only be performed if the vehicle inclination is greater than 10%.
