Removal and installation of the vacuum amplifier of the vehicle equipped with ABS
As mentioned in Section 15.6, the removal of brake booster when installed ABS comes a little like a car without ABS, as in this case it is necessary to remove the hydraulic unit to the ECU - ABS, to gain access to the fastening of the vacuum brake booster. Removing vacuum booster in a car with ABS system performed as follows: - Remove the wire "-" O with AB;

- Remove the baffle compartment AB (see. Fig. 328); - Remove noise insulation in the engine compartment of the engine; - Remove the AB; - Remove the coolant expansion tank; - Disconnect the plug connector Multi-display coolant temperature and remove the two screws; - Unscrew the two screws and remove the right cover partition AB; - Turn away a bolt and remove the left rear compartment bulkhead AB. Put aside the surge tank; - Disconnect the electrical connector on the cover of the brake fluid reservoir and remove the reservoir tank cover; - Remove the spring clamp and disconnect the ABS-ECU Multi-plug connector;
