Brake Parts 1942 80 LS Fire Truck
in Air Systems and Brakes

Where did you get get the brake diagram? I volunteer at the AACA Museum in Hershey and we just got a 1938 Mack fire truck. We want to make sure the brakes are safe as we plan to use the truck for parades. None of us are very familiar with the vacuum assisted brakes on Macks. It would be helpful to us to know the names and functions of the different components. Knowing what vacuum readings are OK would be helpful too. Thanks. Jim
