What the defect is
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 gets fixed
AS NECESSARY, REPLACE FRONT BRAKE CHAMBER MOUNTING BRACKETS AND INSTALL A FRONT BRAKE LIMITING VALVE.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 7 July 1986.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Additional notes
System: brakes. Vehicle description: school buses equipped with a 7500 lb. Front axle and without a front brake limiting valve.

This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
