SERVICE BRAKE PEDAL INSPECTION AND ADJUSTMENT
1.

Turn the stop lamp switch until the clearance between the outer case of the stop lamp switch and pedal arm reaches the standard value, and thensecure the stop lamp switch with the lock nut.

Clearance between pedal and stop lamp switch "A" :

0.5-1.0 mm (0.02-0.04 in.)

2.

Adjust the stop lamp switch until the free play of the brake pedal reaches the standard value.

Brake pedal free play "B" : 3-8 mm (0.12-0.32 in.)

BRAKE BOOSTER OPERATION TEST WITHOUT A TESTER
1.

Run the engine for one or two minutes, and then shut it off. Depress the brake pedal several times at normal foot pressure. If the pedal goes down completely the first time, but rises gradually, the brake booster is functioning properly. If the height of the pedal doesn't change, the booster may be damaged.

2.

After checking that the height of the pedal changes when depressing the brake pedal several times with the engine stopped, start it keeping the brake pedal depressed. At this time, if it goes down slightly, the boosteris good but if the height of it doesn't change, it is damaged.

3.

With the engine running, depress the brake pedal and then stop the engine. Hold the pedal depressed for 30 seconds. If the pedal height does not change,the booster is in good condition. If the pedal rises up, it is damaged.

4.

If one of the above three tests is not OK, check the vacuum hoses, the check valve and the brake booster. Make any necessary corrections. If alltests are OK, the unit is in good condition.

BLEEDING THE BRAKE SYSTEM
1.

Remove the reservoir cap and fill the brake reservoir with brake fluid.

caution

Do not allow brake fluid to remain on a painted surface. Wash it off immediately.

2.

Connect a vinyl tube to the wheel cylinder bleeder plug and insert the other end of the tube in a container of brake fluid which is half full.

3.

Start the engine.

4.

Slowly depress the brake pedal several times.

5.

While depressing the brake pedal fully, loosen the bleeder plug until fluid runs out. Then close the bleeder screw and release the brake pedal.

6.

Repeat steps 4 and 5 until there are no more bubbles in the fluid.

7.

Tighten the bleeder plug screw.

Bleeder screw tightening torque :

7-9 Nm (70-90 kg·cm, 5.2-6.6 lb·ft)

8.

Repeat the above procedure for each wheel in the sequence shown in the illustration.
