REMOVAL & INSTALLATION
See Figures 1 and 2
- Raise and safely support the vehicle with jackstands.
- Remove the wheel and tire assembly.
Do NOT allow the caliper to hang from the brake hose!
- Remove the brake caliper, as outlined earlier in this section, and support with a wire to the surrounding body.
- If equipped, remove the caliper support.
- Remove the rotor assembly.
- Install the brake rotor over the hub assembly.
- If equipped, install the caliper support.
- Install the brake caliper as outlined in this section.
- Install the wheel and tire assembly.
- Carefully lower the vehicle, then firmly pump the brake pedal 3 time before moving the vehicle.
Thickness Variation Check
The thickness variation can be checked by measuring the thickness of the rotor at four or more points. All of the measurements must be made at the same distance from the edge of the rotor. A rotor the varies by more than 0.0005 in. (0.0127mm) can cause a pulsation in the brake pedal. If these measurement are excessive, the rotor should be refinished or replaced.Lateral Runout Check
- Remove the caliper and hang from the body with a piece of wire. Install two inverted lug nuts to retain the rotor.
- Install a dial indicator to the steering knuckle so that the indicator button contacts the rotor about 1 in. (25mm) from the rotor edge.
- Zero the dial indicator.
- Move the rotor one complete revolution and observe the total indicated runout.
- If the rotor runout exceeds 0.0015 in. (0.040mm) have the rotor refinished or replaced.
All brake rotors have a minimum thickness dimension cast onto them. Do NOT use a brake rotor that will not meet minimum thickness specifications in the "Brake Specifications'' chart at the end of this section.
Accurate control of rotor tolerances is necessary for proper brake performance and safety. Machining of the rotor should be done by a qualified machine shop with the proper machining equipment.
The optimum speed for refinishing the rotor surface is a spindle speed of 200 rpm. Crossfeed for rough cutting should range from 0.006-0.010 in. (0.152-0.254mm) per revolution. The finish cuts should be made at crossfeeds no greater than 0.002 in. (0.051mm) per revolution.
