To remove the Mecatronik II hydraulic unit, proceed as follows:
- disconnect the wire from the negative terminal of the battery;
- remove the air filter, air flow meter and all associated pipes and hoses as described in the engine removal subsections;
- completely seal the expansion tank shut-off joint with adhesive tape, which prevents brake fluid from leaking out;
- remove the main brake cylinder together with the expansion tank as described in the relevant section, temporarily move the cylinder to the left side of the left suspension;
- remove the brake booster by unscrewing the brake pedal mount and removing the booster with the shaft as a single unit;
Fig. 269. Disconnecting the tubes from the hydraulic unit
- disconnect all brake pipes from the hydraulic unit (Fig. 269), cover open connection points and pipe ends in a suitable manner (with adhesive tape) to prevent dirt and other foreign objects from getting into them;
Fig. 270. Hydraulic control unit connector
- a multi-pin plug connector is connected to the hydraulic unit, press the safety tab on it and disconnect it (the connector is connected in the place shown in Fig. 270);
Fig. 271. Fastening the pump from the rear side
- unscrew the pump mounting bolts from the back side (Fig. 271), slowly lift the hydraulic device from the left side and remove it from the right support; make sure that none of the fastening parts fall off, on this side there are loose inserts with pin bolts, in addition, the cap with pin screw and insulating ring are free;
- in diesel engines, remove the heat-insulating sheet.
Assemble the hydraulic unit as follows:
- install the cap with the pin screw and the insulating ring;
- insert the unit from the right side, and then the inserts with pin screws into the suspension rubber, and these inserts must be in their place in the holder;
- lower the left end into the holder and tighten the nut shown in Fig. 271 to a torque of 20 N·m;
Fig. 272. Connection points of brake pipes to the hydraulic unit
- perform the remaining work in reverse order (the connection points of the brake pipes are shown in Fig. 272);
- connect the brake pipe leading to the right front brake at point 1;
- connection 2 leads to the front left brake circuit;
- connection 3 is the secondary output (for the intermediate piston) of the master brake cylinder;
- connection 5 leads to the front right brake circuit;
- connection 6 is the outlet of the main brake cylinder's injection piston;
- after assembly, bleed the brake system as described in the relevant section;
- check the operation of the brake system and ABS.
Removal of the Mecatronik III hydraulic unit is carried out in the same order, except for removing the brake booster.
Proceed with further removal as follows:
Fig. 273. Disconnecting the brake pipes on the Mecatronik III hydraulic unit
- disconnect the brake pipes in the places shown in Fig. 273;
- disconnect the brake fluid line from the mounting bracket;
- loosen the bolts on the left side of the hydraulic unit from the holder, and then unscrew the ones on the right side;
- remove the hydraulic unit together with the holder;
- if necessary, disconnect the mounting bracket from the hydraulic unit.
Install in the reverse order of removal. If the hydraulic unit was unscrewed from the mounting bracket, tighten it to a torque of 14 N·m. Tighten the bracket mounting bolts on the right and left to a torque of 25 N·m, the brake pipes to a torque of 14 N·m, then bleed the brake system.
