Chevrolet Citation/Omega/Phoenix/Skylark 1980-1985 Repair Guide

Brake Drums



  1. Loosen the wheel lug nuts. Raise and support the car. Mark the relationship of the wheel to the axle and remove the wheel.
  3. Mark the relationship of the drum to the axle and remove the drum. If it cannot be slipped off easily, check to see that the parking brake is fully released. If so, the brake shoes are probably locked against the drum. See the "Adjustment" information earlier in this guide for details on how to back off the adjuster.
  5. Installation is the reverse. Be sure to align the matchmarks made during removal. Lug nut torque is 102 ft. lbs. (140 Nm).

  1. After removing the brake drum, wipe out the accumulated dust with a damp cloth.

Do not blow the brake dust out of the drums with compressed air or lung-power. Brake linings contain asbestos, a known cancer causing substance. Dispose of the cloth used to clean the parts after use.

  1. Inspect the drums for cracks, deep grooves, roughness, scoring, or out-of-roundness. Replace any drum which is cracked; do not try to weld it up.
  3. Smooth any slight scores by polishing the friction surface with fine emery cloth. Heavy or extensive scoring will cause excessive lining wear and should be removed from the drum through resurfacing, a job to be referred to your local machine shop or garage. The maximum finished diameter of the drums is 7.894 in. (200.64mm). The drum must be replaced if the diameter is 7.924 in. (201.40mm) or greater.
