Does this affect my vehicle?

The manufacturer did not publish a build-date range for this recall, so the model and year list below is the only way to tell whether your vehicle is covered.

  • 1976-1977 Chevrolet G30
  • 1976-1977 Chevrolet P30
  • 1976-1977 GMC G30

What the defect is

On the involved vehicles, the brake master cylinder may have been assembled with reservoir mounting bolts that were improperly processed. This could make these bolts brittle and subject to breaking. If breakage occurs, a brake fluid leak may develop between the reservoir and master cylinder. Loss of brake fluid would adversely affect vehicle braking capability.

What gets fixed

DEALER WILL REPLACE THE MASTER CYLINDER RESERVOIR MOUNTING BOLTS WITH AN IMPROVED TYPE, WITHOUT CHARGE TO OWNER.

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 15 July 1977.

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.

Check your own vehicle

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.
