Brake Rotors
Examine the brake rotors. Original thickness is .1875”
(4.76mm). See Figure 6.27.
The rotors merit replacement if:
• Warpage exceeds .020” (.50mm) total indicated
run-out (T.I.R.)
• The friction surface is deeply scored, pitted, or
erupted.
• Total thickness is less than .125” (3.175mm).
The brake rotors are very similar front to rear, and the
rotor replacement method is identical.
1. Remove the brake caliper as described in the
Brake Pads section of this manual.
See Figure 6.28.
2. Remove and discard the cotter pin that secures
the axle nut. See Figure 6.29.
3. Remove the axle nut and the heavy flat washer
behind it using a 32mm wrench.
4. Affix an automotive hub puller to the axle and
hub assembly. See Figure 6.30.
