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 dial gauge placed at 10 mm (0.39 in) inside
disc edge as shown.

NOTE:
Before measuring, make sure that wheel bearing axial end play
is within the specification. Refer to

RAX-6, "Rear Axle Bearing"

(C200),

RAX-18, "Rear Axle Bearing"

(M226).

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.

THICKNESS

Check the thickness of the disc rotor using a micrometer. Replace
disc rotor if the thickness is less then the repair limit thickness.

INFOID:0000000005272465

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.
