High Temperature RECLAMP

After heavy use of the brakes, the disc temperatures can be extremely high. If the vehicle is stationary and the EPB  is applied, the ABS  automatically reapplies the EPB  . The brake reapply occurs as the brake discs cool down.

A temperature model in the ABS  software calculates the brake disc temperature from:

• The brake application force.
• The time intervals the brake force is applied.
• The vehicle speed.

High temperature reclamp occurs at brake disc temperatures of 250°C (482°F) and above. It also occurs at any temperature when the vehicle is parked on a 20% or steeper slope. Depending on the temperature and inclination, up to 3 reclamps can occur, at varying time intervals. The reclamps are applied in the 10 minutes following the initial application of the EPB  . To limit the number of reclamps, the ignition status as well as the current inclination of the vehicle is considered.
