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 31 October 1975.
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
Mack campaign no n/a.trucks with dual brake treadle valve piping SEPT.1974AND MAR.31, 1975.POSSIBILITY that the primary and secondary air supplylines may have been connected in reverse at the dual brake treadle valve.thereversing of these supply lines does not in itself, affect vehicle braking ifboth the primary and secondary air supply systems have normal operating airpressure.however, in the event of loss of air pressure in either the primaryor secondary system, neither the primary nor secondary service brakes wouldfunction when applied.in this event, it would require manual application ofthe emergency spring brake to stop vehicle.(correct by inspecting andrerouting air supply piping as required to correct system).

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.
