17.7. Check of a regulator of brake forces
THE GENERAL DATA

Necessary adaptations:

– A manometre (double).

By means of manometres to check up serviceability of regulators of brake forces. At check it is necessary to measure pressure simultaneously in the wheel cylinders of a forward and back brake located on a diagonal. At first one contour of system, then the second is checked.

To measure
PERFORMANCE ORDER
1. To turn out the valve of release of air from one of back wheel cylinders and to attach instead of it the first manometre.
2. To turn out the valve of release of air from the forward wheel cylinder located on a diagonal, and to attach instead of it the second manometre.
3. To increase pressure in a hydrodrive, some times strongly having pressed a brake pedal. (The second manometre shows noncontrollable pressure which develops in system).
4. To establish pressure in brake system (on the second manometre) according to the test table. To check up pressure in the back wheel cylinder on the first manometre.
The prevention

At achievement of size of pressure 10 мПа indications of the first manometre will be inexact.


5. To attach manometres to wheel cylinders of the second diagonal contour and to inspect conformity of pressure with the test table.
