The short answer

NHTSA received GENERAL MOTORS CORP.’s report on Jul 7, 1986. Copied from NHTSA on Oct 28, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

The notice gives no hazard in a field of its own.

SEVERE BRAKE CHATTER MAY CAUSE THE BRAKE CHAMBER MOUNTING BRACKETS ON EITHER SIDE TO DEVELOP CRACKS IN THE WELD AREA WHERE THE S-CAM SHAFT TUBE ATTACHES TO THE CHAMBER SUPPORT SECTION.

CONSEQUENCE OF DEFECT: BRACKETS CAN BREAK, RESULTING IN LOSS OF BRAKING ABILITY AT THE FRONT WHEEL, AND POSSIBLY RESTRICT STEERING, WHICH COULD LEAD TO A VEHICLE CRASH WITHOUT PRIOR WARNING.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
