Examination
Firmly depress the brake pedal as far as it will go and quickly release (the vehicle rests on the wheels). The lever of the brake force regulator must move.
Pressure test
Note.
- The brake force regulator is adjusted on a vehicle prepared for movement.
- Vehicle curb weight for monitoring and adjusting the load sensing brake force regulator, vehicle weight with full fuel tank, full washer water reservoir, spare wheel, jack tool kit and driver (75 kg). The spare wheel, tool kit and jack must be in the place designated for this purpose by the manufacturer, the driver must sit in the driver's seat.
1. With the vehicle raised, connect the pressure gauge of the tester to the wheel brake caliper (left front wheel) and to the brake cylinder (right rear wheel).
2. Remove air from both pressure gauges.
3. After lowering the car, shake the rear axle of the car several times (on springs).
4. While pressing the brake pedal, measure the pressure values.
5. Compare the measured values with the required reference values for adjustment.
6. If necessary, adjust the load-dependent brake force regulator.
