1998 NISSAN PATROL air bleeding

Inspection Ð Rotor
RUNOUT
1. Secure rotor to wheel hub with at least two nuts (M12 ý 1.25).
2. Check runout using a dial indicator.
Make sure that wheel bearing axial end play is within the
speci®cations before measuring. Refer to FA section (``Front
Wheel Bearing'', ``ON-VEHICLE SERVICE'').Maximum runout:0.1 mm (0.004 in)
3. If the runout is out of speci®cation, ®nd minimum runout posi- tion as follows:
a. Remove nuts and rotor from wheel hub.
b. Shift the rotor one hole and secure rotor to wheel hub withnuts.
c. Measure runout.
d. Repeat steps a. to c. so that minimum runout position can be found.
4. If the runout is still out of speci®cation, turn rotor with on-car brake lathe (``MAD, DL-8700'', ``AMMCO 700 and 705'' or
equivalent).
THICKNESS
Thickness variation (At least 8 positions): Maximum 0.015 mm (0.0006 in)
If thickness variation exceeds the speci®cation, turn rotor with on-
car brake lathe. Rotor repair limit:30.0 mm (1.181 in)
Assembly
1. Insert piston seal into groove on cylinder body.
2. With piston boot ®tted to piston, insert piston boot into grooveon cylinder body and install piston.
3. Properly secure piston boot
CAUTION:
Secure dust seal properly.
Installation
CAUTION:
+ Re®ll with new brake ¯uid ``DOT 3''.
+ Never reuse drained brake ¯uid.
1. Install caliper assembly.
2. Install brake hose to caliper securely.
3. Install all parts and secure all bolts.
4. Bleed air. Refer to ``Bleeding Brake System'', BR-4.
