14. When disassembling, pay attention to the order of the parts.
15. Assembly is carried out in reverse order, taking into account the following.
16. Check the cylinder diameter in 6 places in mutually perpendicular directions. If the measurement spread exceeds 0.025 mm, replace the cylinder assembly.
17. Check the gap between the piston and the cylinder, which should be no more than 0.15 mm, otherwise replace the cylinder assembly.
18. Replace all seals.
19. Tighten all connections on the cylinder to the required torques.
20. Before installing the cylinder, determine the gap A using the formula A = B – C – D.
21. To determine A, measure the distance B through a plate with an accurately measured thickness.
22. Measure the distance C.
23. Then measure the distance D through the plate with the accurately measured thickness.
24. Calculate distance A. The gap should be 0.1–0.15 mm.
25. If necessary, adjust clearance A by rotating the brake booster rod and measuring distance D.
26. When finished, bleed the brakes.
