Removal

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Unscrew a cover from a popolnitelny tank of brake system and add brake liquid to max label. Put on a mouth of a popolnitelny tank a piece of polyethylene and screw up a cover. It pressurizes a cover of a popolnitelny tank therefore at carrying out further works of loss of brake liquid will be minimum.
3. Clear a place of connection of brake tubes to the hydraulic device and note an arrangement of brake tubes. Unscrew connecting nuts and disconnect tubes from the hydraulic device and close the ends of tubes jams.
4. Unscrew the screw and remove from the hydraulic device a relay cover. Disconnect the electric socket from the hydrodevice, then unscrew a bolt and remove the grounding tire.
5. Unscrew nuts and remove гидравличес which device from an arm.
Prevention

Do not assort the modulator block as its repair is not provided.


Installation

PERFORMANCE ORDER
1. Installation is made in sequence, return to removal taking into account the next moments:
a–check a condition of rubber plugs and, if necessary, replace them;
b–connect to the hydraulic block brake tubes and fix them connecting nuts, having tightened them the demanded moment;
c–before installation of the accumulator of pressure remove air from hydraulic system.
