10.6.4. Check of wheel cylinders of back brakes at the stand

The scheme of check of wheel cylinders of back brakes

1 – an emphasis of pistons;
2 – the tested cylinder;
3 – a cylinder arm;
4 – a manometre of low pressure;
5 – a high pressure manometre;
6 – the cylinder for pressure creation;
7 – a vessel;
8 – a flywheel

PERFORMANCE ORDER
1. Before check be convinced that details of the working cylinder freely move in the cylinder.
2. Establish the cylinder on the stand, attach to it the pipeline from manometres and pump over system.
3. Adjust an emphasis 1 so that pistons have been moved apart on the greatest distance.
4. Check up absence of leak of a liquid. Connect a manometre of low pressure; slowly rotating a flywheel of management of the drive cylinder, establish pressure of a liquid 0,05 МПа (0,5 kgs/sm2).
5. Be convinced that the established pressure is kept within 5 minutes
6. Repeat similarly test at pressure 0,1–0,2–0,3–0,4–0,5 МПа (1–2–3–4–5 kgs/sm2).
7. Lower pressure and connect a high pressure manometre.
8. Adhering to the specified rules, repeat tests at pressure 5–10–15 МПа (50–100–150 kgs/sm2). Pressure decrease because of liquid leak through sealing elements, connections of pipelines, the union for prorolling of a liquid or through a casting time is not supposed. It is supposed insignificant (no more than 0,5 МПа (5 kgs/sm2) during 5 mines) pressure reduction, especially at more high pressures, because of усадки sealants.
