In order to optimally use the hill-start assistant, the control unit requires additional information. The spindle is connected to the pressure nut by a self-locking thread. A plate test bench is unsuitable for this task. A wrap spring is installed to ensure that the entire holding force of the parking brake (when applied) is not exerted entirely on the plastic gear wheels. car parking limited but very close to town centre.

As is the case for many other electrical systems, the diagnostic unit can be used to read out the fault memory. Electromechanical parking brakes (EPB) are increasingly being used as an "electronic hand-brake" in the latest generation of passenger cars. Look to see what's been cancelled or postponed. Instead, it acts on the duo-servo drum brake. The electric motor incorporates a stroke sensor – which counts the number of turns the motor makes in operation – and a cable tension sensor. This needs to be guided through a guide tube, to a gear wheel, into the actuator. If this occurs, the parking brake of the automatic transmission is still engaged. Please note that the parking brake can also be activated with the ignition switched off. When you press the switch, the parking brake closes relatively quickly and cannot be applied slowly and continuously as is the case for a manually operated parking brake. The wrap spring is attached to the spindle. For this purpose, open the cover of the emergency release in the left-hand footwell. Only then is it possible to press the brake piston back. Both vehicles have an emergency release enabling the driver or the workshop to unlock the brake in the case of system failure. The cylinder then presses the brake pads to the brake disc via the brake piston. The components are attached directly to the rear brake calipers and enable the rotation of the motor to be converted into small brake piston lifting movements. The parking brake is activated by pulling the switch and released by pressing the switch. The brake is then released and is ready for operation again. Before the brake pads can be removed, the cylinder needs to be completely moved back with the diagnostic unit using the "basic setting" function. The indicator lamp in the display goes out. Due to this rotation in the opposite direction, the first windings of the wrap spring are pressed outward against the surrounding housing. Then the brake is applied and the brake position is initialised. In order to avoid operating errors (function triggered by passenger), the emergency braking is deactivated if the driver accelerates again. The spindle also makes it possible for the wheel to achieve what we call the caster or castor angle, which is the negative and positive tilt essential for the upper and lower steering pivot points. The pulleys are fastened to the balance beam by connection levers. AIMS delivers worldwide. The brake piston houses a cylinder that can move back and forth inside the piston. Please make sure that the information provided is correct. As a result, information on the engaged drive position, the accelerator pedal position, and the engine torque, as well as the tilt angle sensor integrated into the control unit, is taken into account via the CAN bus. This relieves the burden on the driver as they do not always need to press the foot brake.
