INFOID:0000000009484636
PAD WEAR
Check pad thickness from the inspection holes on cylinder body.
Check using a scale if necessary.
DISC ROTOR
DISC ROTOR : Inspection
INFOID:0000000009484637
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
.
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, refinish disc rotor using Tool.
