Cars without adjustable ground clearance
In the Audi 100, the brake force regulator is located on the left side in front of the rear axle. It can reduce the fluid pressure in the rear wheel cylinders.
This happens depending on the load: when the car is fully loaded, the rear part of the body drops under a small load; if one or two people are sitting in the car, the deflection of the rear springs is small. Due to excessive pressure on the rear wheels, they lock prematurely, and the car can turn sideways when braking.
The brake force regulator receives information about the vehicle's loading status via a spring connected to the rear axle, depending on how low the rear axle has dropped.
In cars with adjustable ride height, the brake force regulator is controlled hydraulically. Adjustment at home is not possible.
Checking the brake force regulator. Cars without adjustable ground clearance
To quickly check the action, you will need an assistant. The car should not be raised with a jack.
Press the brake pedal sharply all the way down and quickly remove your foot.
At the same time, the brake force regulator lever should move.
For a more precise check, as well as for checking the hydraulic brake force regulator, special tools are required.
Note: The brake force regulator drive can be adjusted. Adjustment is required if the braking force of the rear wheels is too low or if the rear brakes lock, as well as if tuning has been carried out that changes the freedom of the underbody.
