Cadillac Seville Parking Brake

Q. HI, I have a 1979 Cadillac Seville and cannot properly adjust the rear emergency brake system. There has to be somebody that can give me some advice on how to adjust the rear disc brakes.

Thanks,
John

Cadillac Seville Parking Brake

A. Well John, you didn't say if it has drum or disc brakes in the rear so I guess I'll have to give you the adjustment procedure for both.

With Rear Disc Brakes

  1. Lubricate parking brake cables at equalizer and underbody rub points. Check all cables for freedom of operation.
  2. Fully release parking brake and raise vehicle.
  3. Hold cable stud from turning and tighten equalizer nut until cable slack is removed and levers are against stops on caliper housing. If levers are off stops, loosen cable until levers return to stop.
  4. Operate parking brake several times to check adjustment. When properly adjusted, the parking brake pedal should move 5¼" to 6¾" on all except Seville and Eldorado or 4" to 5½" on Eldorado and Seville.

With Rear Drum Brakes

  1. With service brakes properly adjusted, lubricate parking brake linkage at equalizer and cable stud with heat-resistant lubricant, and check for free movement of cables.
  2. Depress parking brake pedal about 1½" from full released position.
  3. Raise rear wheels off floor.
  4. Hold brake cable and stud from turning and tighten equalizer nut until a slight drag is felt on either wheel (going forward). After each turn of equalizer nut, check to see if either wheel begins to drag.
  5. Release parking brake. No brake drag should be felt at either rear wheel. Operate several times to check adjustment. When properly adjusted, the parking brake pedal should move 5¼" to 6¾".
