INFOID:0000000009466578

VISUAL

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

RUNOUT

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

positions). 

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

disc edge.

NOTE:

Before measuring, make sure that wheel bearing axial end play

is within the specification. Refer to 

RAX-5, "Inspection"

.

3. When runout exceeds limit value, displace mounting positions of disc rotor by one hole. Then find a posi-

tion of the minimum value for runout. 

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

Tool.

THICKNESS

Check the thickness of the disc rotor using a micrometer. Replace

disc rotor if the thickness is less than the wear limit.

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.
