  A: The hydraulic brake booster disassembly requires starting with No. 1 brake actuator bracket removal through hexagon wrench (5 mm) screw extraction followed by disconnecting the fluid level warning switch connector with a screwdriver. Disassembly of the brake master cylinder reservoir sub-assembly starts with removing the screw and continuing with pin punch extraction of the pin which allows the reservoir to be removed while the 3 grommets and cap also need to be extracted.
