The valve of adjustment of brake pressure is established or in wheel brake cylinders (with drum-type brakes), or two valves on the lower part of a body are established and connected by a spring and a bar to the lever on a back suspension bracket. Valves carry out two functions:
They distribute brake liquid diagonalno between lobbies and back wheels.
They reduce brake pressure on back wheels at strong braking according to loading. Removal and valve installation — is simple operation, however weakening of a bolt of fastening of a bar on the lever demands new adjustment. For the solution of this problem it is necessary to mark the provision of fastening of the valve. Fastening has a longitudinal opening. Watch, separate pipelines are connected to what channel. After installation adjustment should be checked in a workshop.
After valve installation the brake system should be pumped over.
The valve does not understand and in case of breakage is replaced with the new.
It is possible to check operability of the valve, moving on the dry street with speed of 50 km/h and having made emergency braking (it is obligatory to be convinced that in front and behind there are no vehicles). The valve works correctly if lobbies and back wheels are blocked at the same time, or forward wheels are blocked before the back. The valve does not work, if back wheels brake before lobbies.
