Start the procedure of Hydraulic Control Assembly for Antilock Brake removal by disconnecting the cable from the negative battery terminal but some systems need initialization post-reconnection. The next step requires complete removal of the radiator reserve tank assembly combined with its attached cap. The suction hose sub-assembly must be separated from the brake actuator bracket assembly before removing the clamp to detach the brake actuator with bracket. The six brake lines from the brake actuator with bracket need to be unscrewed using 10 mm and 12 mm union nut wrenches while documenting all connection points for proper reinstallation. You should use a lock lever to disconnect the brake actuator connector while avoiding brake fluid entry into the removed part. The brake actuator with bracket can be extracted from the body by first removing both bolts and the nut while cautioning against breaking the wire harness or brake lines. The process ends by unscrewing the two nuts which frees the brake actuator assembly from its bracket assembly position.

Proceed to install the radiator reserve tank assembly and its cap.
