The vehicle is braked using a vacuum-assisted hydraulic drive. The hydraulic drive is connected via the ABS module with the HCU to the front and rear brake calipers. To increase safety, the hydraulic system has a dual-circuit design with diagonal division. The hydraulic drive consists of primary and secondary brake circuits. Each circuit runs between the master cylinder and each front and opposite rear wheel.
The braking system is equipped with an anti-lock braking system, which should help the driver control the car in all driving and maneuvering conditions. The sophisticated functionality of the ABS also combines with other systems controlled by the car's software to help maintain directional stability and control when driving off-road.
The parking brake is a cable-actuated mechanical system that acts on brake shoes located inside each rear brake disc.
Front and rear disc brakes
The 3.2 L i6 is equipped with ventilated front and rear disc brakes. The 2.2 L TD4 is equipped with ventilated front and monolithic rear disc brakes. On the i6 and TD4 cars, all disc brakes use a single piston and floating calipers. For more information, see the chapter:
- Front Disc Brake (206-03 Front Disc Brake, Description and Operating Principle)
- Rear Disc Brake (206-04 Rear Disc Brake, Description and Operating Principle)
Parking brake
The parking brake is a cable-operated, hand-actuated system. The right and left rear brake discs have built-in brake drums that contain the brake shoes and parking brake components. For more information, refer to the chapter: Parking brake (206-05 Parking brake and parking brake actuator, Description and operating principle).

Hydraulic brake drive
The hydraulic brake system consists of a brake pedal, master cylinder, HCU and connecting hydraulic lines and hoses. The tandem master cylinder with reservoir is attached to the brake booster and is driven by it. The master cylinder has a tandem design and provides pressure to two independent hydraulic circuits (primary and secondary).
For more information, refer to the chapter: Hydraulic Brake System (206-06 Hydraulic Brake System, Description and Operating Principle).
Vacuum brake booster
The vacuum brake booster uses vacuum to operate. It serves to increase the efficiency of the hydraulic brake drive. The booster has a tandem design, which includes two separate diaphragms. On both gasoline and diesel models, the vacuum required for the booster to operate is created by a vacuum pump driven by the engine.
For more information, refer to the chapter: Brake Booster (206-07 Brake Booster, Description and Operation).
Anti-lock braking system
The ABS system is equipped with a Continental Teves Mk25E1 ABS module with an integrated 4-channel HCU. The ABS module and HCU provide control over the braking system and also provide active braking functions to manage the vehicle's directional stability and traction. The ABS module also provides special functions to facilitate vehicle control when driving off-road.
The anti-lock braking system provides the following functions:
- Anti-lock braking system (ABS)
- Cornering Brake Control (CBC)
- Dynamic Stability Control (DSC)
- Electronic Brakeforce Distribution (EBD)
- Electronic Traction Control (ETC)
- Emergency Brake Assist (EBA)
- Engine Drag Torque Control (EDC)
- HDC (High Descent Control) system with gradual release
- Roll Steering Control (RSC)
- Terrain Response™ System Integration
For additional information, refer to the chapter: Anti-lock Braking System - Directional Stability Assist Function (206-09C Anti-lock Braking System - Directional Stability Assist Function, Description and Operation).
