Air Brake Accuators

[timvasqz]

if you open up the pot all you need to do is replace the diaphram. Here is a
good diagram of how the two work.

the double pumkin one which has the spring brake is the dangerous one. the
single pumkin one has a return spring only. you can be shure by pulling on the
lever if it wont move it is high pressure the other one is easy to move.

Probably the dirtiets shop I have ever seen. The service is outside. A few pits
and one big steel ramp that you can drive up onto. Inside it was cleaner. He
sold clutches and reriveted blocks. He also resurfaced flwheels. Even had a nice
Czech lathe ( they are the best). He had these steel tables made from huge
flwheels. Must have been from mining equipemnt. They had built jigs to hold the
brake pots and had air cylinders that held them together while you undid the
bands. Very ingenious.For a few dollars they did it all and I was safe!
