Control of work
1. With the engine off, press the brake pedal several times to relieve the booster.
2. Press the pedal and start the engine. If the pedal moves down easily, the booster is working normally.
3. Let the engine run for about two minutes and turn it off. Slowly press the brake pedal several times. If the pedal travel increases with each press, there are no leaks in the booster.
4. Press the pedal while the engine is running. Turn off the engine without releasing the pedal. If the pedal does not change its position within 30 seconds, the booster is OK.
Removal
5. The brake booster is a non-separable unit. If the booster fails, replace it with a new one.
6. Remove the brake master cylinder (see Section 7).
7. Locate the connection between the brake pedal and the booster (see fig. 8.1): it is located under the dashboard opposite the driver's seat.
8. Remove the pin cotter pin and take out the pin.
9. Holding the earring with pliers, disconnect the lock nut, remove the earring.
10. Disconnect the hose from the engine to the booster. Do not damage the hose or the booster pipe.
11. Unscrew the four nuts securing the amplifier to the engine compartment wall.
12. Remove the amplifier, bracket and gaskets.
Installation
13. The installation procedure is basically the reverse of disassembly. Tighten the earring nut and the amplifier mounting nuts.
14. After installing the booster, it is necessary to adjust the clearance between the pusher and the piston of the master brake cylinder. Measure the distance between the piston seat of the cylinder and the plane of the mounting flange. Apply a vacuum of 20 mm Hg to the booster and measure the distance between the pusher of the booster and the installation plane of the master cylinder (including gasket). Compare the two measurements and get the required clearance (see fig. 11.14a). If the gap is more or less than recommended (see specification). loosen the lock nut and adjust the clearance (see fig. 11.14b). After adjustment, tighten the lock nut.
