Brake force distributor

Brake force distributor:
The brake force distributor distributes the braking force between the front and rear wheels. A car always has to brake harder at the front than at the rear. This is about the 60-40% ratio. The front wheels brake 60% and the rear wheels brake 40% of all braking power.
A car always dives forward with brakes. Most of the weight is then placed on the front wheels. This reduces the weight on the rear wheels. If the rear wheels were to brake harder or as hard as the front wheels, they would immediately block because there is almost no weight on them. The result is that the wheels start to slip and the risk of an accident is high.

The brake force distributor is mounted in front of the rear axle of the car. When the brakes are applied and the car dives forward, the rear axle springs out. The brake power distributor is then actuated and squeezes the brake fluid pressure to the rear wheels. Less pressure from the brake fluid is then applied to the rear brakes, so that they brake less hard.
If the car brakes even harder, the rear axle will spring out even further. The brake power distributor now allows even less brake fluid to pass through to the rear brakes.
When the car stops braking, the car no longer dives forward. The rear axle and the brake force distributor now return to the neutral position.

The brake force distributor is a mechanical component. Over time, different weather conditions can reduce the hinge effect. It is possible that the brake force distributor sticks and there is almost no brake pressure at the rear wheels. This is noticed quickly enough at the MOT at the brake test bench. This is a rejection point. In this case, the brake force distributor must be disassembled/assembled, cleaned and lubricated.

A photo of the brake power distributor will follow shortly.
