Normal Braking

Using a conventional, diagonally-split brake system and an add-on type Antilock Brake System (ABS) unit, the brake system operates normally while the Antilock Brake System monitors wheel speeds and brake pedal position. The conventional system continues to operate normally until the Electronic Brake and Traction Control Module (EBCM/EBTCM) detects a wheel beginning to lock. When this wheel locking condition exists, the brake system transfers from normal braking to antilock braking modes. The antilock brake system remains in control until braking is no longer required, or the wheel locking and/or an excess pedal travel condition cease(s) to exist.
