Air Lines In Truck:

[Rob]

Today I went to move my 74 RL and upon mashing the brake release button, promptly blew a brake hose feeding the rear rear brake chambers from the frame mounted quick release valve. This truck has wedge brakes that work very well. They are completely rebuilt and offer no problems. However, every air line on this truck is "Aeroquip" style braided and this line is horrendously expensive. I know all the newer trucks are plastic, but I'm wondering if there are any alternatives less expensive? I'll bet a guy could spend over a thousand dollars just in air line used in the braking system if they wanted to; I don't unless necessary, but I do plan to replace everything when the truck is rebuilt.

Any ideas? Does any line need to be DOT stamped to not be put out of service?

Thanks,

Rob

The nylon/plastic airline is DOT stamped. It is much easier to replace later on, as well as cheaper, however in converting from Aeroquip to nylon/plastic I would expect the largest part of the budget would go towards brass fittings which will have to be changed at the same time.

Been looking into that cost. I have several rolls of plastic line in differing sizes. The fittings can be purchased for both ends of the plastic line at less money than three feet of -6 line in Aeroquip style hose. That stuff is very high dollar. Kinda like to stay original but the cost seems to be prohibitive when working with low pressure pneumatics.
