MINI brake system

MINI models are equipped with vacuum-assisted four-wheel disc brakes. Single-piston calipers act on vented front and solid rear rotors (discs). A brake pad wear sensor for each axle indicates when brake pads need replacement.

The parking brake system is integrated with the rear brake calipers and rotors

Electronic braking; stability and traction control features on MINI models are as follows:

• Antilock Braking System (ABS) is standard in all models
• Automatic Stability Control (ASC) is optional in Cooper models; standard in Cooper S models.
• Dynamic Stability Control (DSC), otherwise known as traction control, is an option on all MINI models.

Antilock Braking System (ABS)

ABS prevents road wheel lock-up during brake application; thus maintaining vehicle stability and steering control under emergency conditions. Fitted to all MINI models, ABS is always active when the vehicle is being driven and cannot be disabled by the driver .

ABS components

• Hydraulic control unitelectronic control module is mounted in the right rear of the engine compartment in an insulated chamber.
• The aluminum hydraulic body contains the valves that control pressure to the individual brake lines.
• The cylindrical is the electrically driven hydraulic pump. part
• The plastic molded is the electronic control module_ part

Wheel speed sensors are located at each of the four wheel hubs. The sensors are of the magnetoresistive type.

Brake light switch, mounted to the pedal cluster support bracket, is a Hall effect sensor supplying brake application information to the ABS control module.

Brake fluid level sensor contacts remain closed if hydraulic brake fluid level is correct. If fluid level fall below the minimum required; the switch opens

ABS warning LED (amber), located in the instrument cluster, is ON during predrive self-check or when the system detects a fault.

ABS operation

The four ABS wheel sensors monitor the rotational speed of each wheel and signal the information to the ABS control module. If, during braking; one or more wheels decelerate at a rate that exceeds a programmed value, the ABS control module activates the ABS hydraulic unit and reduces the hydraulic brake pressure supplied to the affected wheel(s).

During antilock brake operation the driver will experience feed-back in the form of a pulsating brake pedal that is accompanied by solenoidlpump noise.

All versions of MINI are equipped with Teves Mk 60 ABS, which includes the following subfunctions:

Electronic Brake Force Distribution (EBV) controls the distribution of hydraulic brake pressure between the front and rear wheels. This is necessary to optimize the efficiency of the brakes under varying vehicle load conditions. It also allows larger rear brakes to be specified and ensures that front and rear brake linings wear at a similar rate.

Brake force is applied by the ABS hydraulic pressure pump to individual wheels in unloaded and fully loaded conditions.

EBV is in all MINI models and cannot be disabled by the driver .

Cornering Brake Control (CBC), together with EBV, helps to keep the vehicle under control under all braking; vehicle loading and steering conditions.

When the brakes are applied, weightis transferred to the front axle of the vehicle. If this occurs during cornering or directional change; the self-steering properties of the vehicle have a tendency to turn the vehicle into the curve (slight oversteer) . This tendency is normally com pensated for by the design characteristics of the suspension and by intuitive steering adjustment by the driver.

CBC adjusts hydraulic
