Removal & Installation
CAUTION:
The vacuum in the power brake booster must be pumped down before removing the master cyl-
inder to avoid damaging the master cylinder and to prevent the booster from sucking in any con-
tamination. This can be done by pumping the brake pedal while the engine is not running until a
firm brake pedal is achieved.
1. Turn the ignition switch off.
2. Siphon out as much brake fluid as possible from the master cylinder.
3. With the engine off, pump the brake pedal 4 - 5 strokes until the pedal feel is firm.
4. Disconnect the negative battery cable.
5. Disconnect the brake tubes at the master cylinder outlet ports. Install plugs at all of the open brake tube outlets
on the master cylinder.
(Tighten: Brake tube nuts to 10 N·m)
6. Clean the area around where the master cylinder attaches to the power brake booster using a suitable brake
cleaner such as Brake Parts Cleaner or an equivalent.
7. Remove the two nuts (1) attaching the master cyl-
inder to the power brake booster.
(Tighten: Master cylinder mounting nuts to 23 N·m)
8. Disconnect the brake fluid level switch electrical
connector (2) from the master cylinder brake fluid
reservoir.
9. Slide the master cylinder straight out of the power brake booster.
10. Installation is in the reverse order of removal.
NOTE: After installation, bleed the master cylinder or bleed the entire brake system as necessary.
