THE GENERAL DATA

Regulator of pressure of the car "Toyota 4 Runner/Hilux/Surf"

1. An arm
2. A regulator
The pressure regulator is intended for change of pressure in a contour of brakes of forward and back wheels depending on loading on forward and back axes. Loading on a forward axis of not loaded lorry exceeds loading on a back axis, therefore at braking pressure in a contour of forward brakes should be above than a contour back. If in the car there is a cargo loading on a back axis can exceed loading on a lobby. Therefore, the regulator of pressure of considered cars provides pressure redistribution in contours of brakes depending on cargo.

Sensitive element of a regulator of pressure is the spring which is stretched depending on cargo weight. The initial tension of a spring is regulated. Into regulator structure enters dosing out and перепускной valves.

Repair regulator adjustment are carried out only in car-care centre, it is independently possible to perform works on removal and installation (replacement). At a detachment of a rod of a regulator in case of dismantle of the back bridge unit adjustment is not required.


The prevention

After replacement of its regulator it is necessary to check up at the special stand in car-care centre.
