Brake Booster

The first step for vacuum brake booster removal requires the draining of brake fluid before washing all fluid which contacts painted areas. The first step requires the removal of windshield wiper arm covers and subsequent disassembly of front wiper arms and blades from both the left and right sides. The installer should now proceed to remove first the hood to cowl top seal and then both right and left cowl top ventilator louvers. The work procedure includes elimination of the front wiper motor together with link and also the outer cowl top panel and the air cleaner assembly. The service procedure starts by disconnecting the clutch reservoir tube used for manual transaxle systems followed by removing the brake master cylinder sub-assembly together with the brake actuator assembly. The procedure requires removal of the instrument panel finish lower panel sub-assembly followed by separation of the brake master cylinder push rod clevis. Remove the brake booster assembly after detaching the vacuum hose from the check valve using the clip then unfastening four nuts to safely retrieve the assembly without harming brake tubes. Detach the brake booster assembly gasket before slowly loosing the push rod lock nut to remove the push rod clevis. The brake vacuum check valve assembly must be removed after separating it from the brake booster assembly and removing the grommet from the brake booster assembly.

First, drain the brake fluid, ensuring to wash off any fluid that contacts painted surfaces.
