  A: The first step to remove a Vacuum Brake Booster requires draining all brake fluid before washing off fluid contact points with painted surfaces. You should start by removing the windshield wiper arm cover before working on the front wiper arm along with blade assembly on both left and right sides. Moving on, remove the hood to cowl top seal as well as the cowl top ventilator louver on both left and right sides alongside the front wiper motor and link. Remove the air cleaner assembly followed by the outer cowl top panel from the procedure. The first step requires disconnecting the clutch reservoir tube of the manual transaxle followed by brake master cylinder and brake actuator assembly removal. The next stage includes removing the instrument panel finish lower panel sub-assembly while disconnecting the brake master cylinder push rod clevis. The process ends with brake booster assembly removal by separating the vacuum hose from the check valve using the clip then removing 4 nuts to remove the assembly without harming brake tubes. Release the gasket from the brake booster assembly while one must loosen the push rod lock nut followed by removing the push rod clevis. The brake vacuum check valve assembly removal process begins with extracting it from the brake booster assembly followed by the grommet removal from the brake booster assembly.
