22.21.2.3 Pressure accumulator

Removal

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Unscrew screws and uncover the hydraulic device.
3. Dress a pure transparent hose on the union of pumping of the hydraulic device (SP label) and the second end of a hose establish in a vessel. Unscrew the union of pumping and merge brake liquid in a vessel.
4. Disconnect tubes of the accumulator of pressure from the basis of the hydraulic device.
5. Tighten the parking brake, then lift a forward part of the car and fix on supports. Remove the left forward wheel.
6. Unscrew screws and remove protection of a wing from under an arch of the left wing.
7. Unscrew the nuts, pressure fixing the accumulator to an arm, then, being careful, remove the pressure accumulator together with tubes.

Installation

PERFORMANCE ORDER
1. Installation is made in sequence, return to removal taking into account the next moments:
a–at installation check correctness of connection of tubes to the hydraulic device;
b–tighten connecting nuts of fastening of tubes the demanded moment;
c–remove air from brake system and the hydraulic device.
