If the vacuum supply fails, the brake pedal rod will 
contact the end of the master cylinder actuator rod 
and the system will apply the brakes without any 
power assistance. The driver will notice that much 
higher pedal effort is needed to stop the car and that 
the pedal feels harder than usual. 
Vacuum leak Test 
1. Operate the engine at idle without touching the 
brake pedal for at least one minute. 
2. Turn off the engine and wait one minute. 
3. Test for the presence of assist vacuum by de- 
pressing the brake pedal and releasing it several

is no vacuum, air is leaking into the system. 
System Operation Test 
1. With the engine OFF, pump the brake pedal 
until the supply vacuum is entirely gone. 
2. Put light, steady pressure on the brake pedal. 
3. Start the engine and let it idle. If the system is 
operating correctly, the brake pedal should fall to- 
ward the floor if the constant pressure is maintained. 
Power brake systems may be tested for hydraulic 
leaks just as ordinary systems are tested.

To install: 
4. 
Install the new switch and install the locknut, 
tightening it just snug. 
5. Reposition the brake light switch so that the 
distance between the outer case of the switch and the 
pedal is 0.02-0.04 in. (0.5-l .Omm). Note that the 
switch plunger must press against the pedal to keep 
the brake lights off. As the pedal moves away from 
the switch, the plunger extends and closes the 
switch, which turns on the stop lights. 
6. 
Hold the switch in the correct position and 
tighten the locknut.

2. Remove the master cylinder reservoir cap, 
then use a clean turkey baster or equivalent to siphon 
out as much fluid as possible and place in a suitable

brake fluid. If you do get brake fluid in your 
eyes, flush your eyes with clean, running wa-

or if you have taken brake fluid internally, 
IMMEDIATELY seek medical assistance. 
3. Disconnect and plug the lines from the brake

10. Install the master cylinder reservoir, securing 
the retainers. 
11. Attach the fluid level sensor connector, then 
unplug and connect the fluid lines to the reservoir. 
12. The remainder of installation is the reverse of 
the removal procedure. Fill the reservoir with the 
proper type and amount of DOT 3 brake fluid from a 
fresh, sealed container.

Clean, high quality brake fluid is essential to 
the safe and proper operation of the brake 
system. You should always buy the highest 
quality brake fluid that is available. If the 
brake fluid becomes contaminated, drain and 
flush the system, then refill the master cylin- 
der with new fluid. Never reuse any brake 
fluid. Any brake fluid that is removed from 
the system should be discarded. Also, do not 
allow any brake fluid to come in contact with 
a painted surface; it will damage the paint. Measure the brake pedal height from the floor of 
the vehicle to the upper surface of the brake pedal. 
The distance should be 6.9-7.1 in (176181mm). If 
the brake pedal height is incorrect, adjust as follows: 
1. Detach the stop lamp switch connector. 
2. Loosen the locknut on the base of the stop 
light switch and move the switch to a position where 
it does not contact the brake pedal. 
3. Loosen the operating rod locknut. Adjust the 
height of the brake pedal by turning the operating rod 
using pliers. Once the desired pedal height is ob- 
tained, tighten the locknut on the operating rod. 
4. Screw the stop light switch until the it contacts 
the brake pedal stopper. Turn switch in until the 
brake pedal just starts to move. At this point, return 
(loosen) the stoplight switch $-1 turn and secure in 
this position by tightening the locknut. In this posi- 
tion, the distance between the lower stop light switch 
case and the brake pedal stop should be 0.02-0.04

5. Attach the electrical connector to the stop light 
switch.

brake unit. 
4. Disconnect the vacuum hose from the

the brake booster vacuum hose. 
5. Detach the electrical harness connector from 
the brake level sensor. 
6. Remove the nuts attaching the master cylin-

and position aside. If necessary, disconnect and plug 
the brake fluid lines at the master cylinder. 
7. From inside the passenger compartment, re- 
move the cotter pin and clevis pin that secures the 
booster pushrod to the brake pedal. 
8. From inside the vehicle, remove the nuts that 
attach the booster to the dash panel. Remove the 
brake booster from the engine compartment. 
To install: 9. Install the brake booster to the dash panel. 
From inside the vehicle, install the attaching nuts and 
tighten to 12 ft. Ibs. (17 Nm). 10. Apply grease to the clevis pin and install with 
washers in place. Install new cotter pin and bend to

12. Install the master cylinder assembly to the 
mounting studs on the brake booster. Install the mas- 
ter cylinder mounting nuts and tighten to 9 ft. Ibs. (12

13. Reconnect the brake fluid reservoir to the 
master cylinder, if disconnected. Attach the electrical 
connector to the brake fluid level sensor. 
14. Install the solenoid valve assembly and the 
relay box, if removed.
