INFOID:0000000006245700

PAD WEAR

Check pad thickness from the inspection holes on cylinder body.

Check using a scale if necessary.

DISC ROTOR
DISC ROTOR : Inspection

INFOID:0000000006245701

VISUAL

Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace as necessary.

RUNOUT

1. Attach disc rotor to wheel hub using wheel nuts at two or more

positions. 

2. Inspect runout using a dial gauge placed at 10 mm (0.39 in)

inside the disc edge.

NOTE:

Before measuring, make sure that wheel bearing axial end play

is within the specification. Refer to 

FAX-6, "On-Vehicle Inspec-

tion and Service"

.

3. When runout exceeds limit value, displace mounting positions of disc rotor by one hole. And then find a

position of the minimum value for runout.

4. If runout is outside the specified value after performing the above operation, turn disc rotor using Tool.

BRAKE BOOSTER

BRAKE BOOSTER

Inspection

INFOID:0000000006245704

OPERATION

With engine stopped, change vacuum to atmospheric pressure by

depressing brake pedal several times. Then with brake pedal fully

depressed, start engine and when vacuum pressure reaches the

standard, make sure that clearance between brake pedal and floor

panel decreases.

AIR TIGHT

• Run engine at idle for approximately 1 minute, and stop it after

applying vacuum to booster. Depress brake pedal normally to

change vacuum to atmospheric pressure. Make sure that distance

at intervals of 5 seconds between brake pedal and floor panel

gradually increases.

• Depress brake pedal while engine is running, and stop engine with pedal depressed. The pedal stroke

should not change after holding pedal down for 30 seconds.
