DISASSEMBLY AND REASSEMBLY
Caution
(1) On the vehicles with ABS or ACD, when the drive shaft is disassembled or reassembled, be
careful not to interfere with the rotor for wheel speed sensor installed to the B.J. outer race
to prevent the rotor from damage.
(2) Never disassemble the B.J. assembly except when replacing the B.J. boot.

REMOVAL AND INSTALLATION
Caution
1. If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to
contact the parts or tools to the caliper because the paint of caliper will be scratched. And
if there is brake fluid on the caliper, wipe out quickly.
2. With the part marked with *, first temporarily tighten it, then ground the vehicle and tighten
it to specification in unloaded condition.

BRAKE FLUID LEVEL SENSOR CHECK
The brake fluid level sensor is in good condition if there is
no continuity when the float surface is above “MIN” and if
there is continuity when the float surface is below “MIN”.
DISC BRAKE PAD CHECK AND REPLACEMENT

NOTE
The wear indicator contacts the brake disc when the brake
pad thickness reaches approximately 2 mm and emit a
squealing sound to warn the driver.
1. Check the brake pad thickness through the caliper body
check port.
Standard value: 10.0 mm
Limit: 2.0 mm
2. When the thickness is less than the limit, always replace
the pads at an axle set.
3. Remove the pin bolt. Pivot the caliper assembly and hold
it with wires.
Caution
Do not wipe off the special grease that is on the pin
or allow it to contaminate the pin.
4. Remove the following parts from the caliper support.
1. Pad and wear indicator assembly
2. Pad assembly
3. Clip
4. Outer shim
5. In order to measure the brake drag force after pad
installation, measure the rotary-sliding resistance of the
hub with the pads removed. (Refer to P.35A-21.)
6. Install the pads and caliper assembly, and then check
the brake drag force. (Refer to P.35A-21.)
