Brake Rotor (Disc)

REMOVAL & INSTALLATION

Navajo and B Series Pick-up Models
EXCEPT 1995–98 4-WHEEL DRIVE MODELS
  1. Loosen the wheel lug nuts.
  2. Jack up the front of the vehicle and support on jackstands.
  3. Remove the wheel and tire.
  4. On 1994 models, remove the brake caliper assembly as described earlier in this Section, but do not disconnect the brake hose.
  5. On 1995–98 models, remove the two anchor plate-to-steering knuckle bolts then slide the assembly off of the rotor.
  6. Suspend the caliper assembly by a piece of wire. Do not allow it to hang by the brake hose.
  7. Follow the procedure given under wheel bearing removal in Section 7 for models with manual and automatic locking hubs.

    NOTE: New rotor assemblies come protected with an anti-rust coating which should be removed with denatured alcohol or degreaser. New hubs must be packed with EP wheel bearing grease.

  8. Installation is the reverse of the removal procedure.

CAUTION
Brake pads contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

  1. Raise and safely support the vehicle. Remove the wheel and tire assembly.
  2. Remove the caliper and support it aside with mechanic's wire; do not let the caliper hang by the brake hose. Remove the disc brake pads and mounting support.
  3. Remove the attaching screw and remove the rotor.
  4. Inspect the rotor for scoring, wear and runout. Machine or replace as necessary.
  5. If rotor replacement is necessary on pickup models, remove the attaching bolts and separate the rotor from the hub.
