I'm new to this site but I have been restoring my grandfather's '73 Mach 1 since January. It needed a lot of work but I'm finally getting close to finishing it. Right now I'm having trouble with bleeding the brakes. I have already replaced the calipers, wheel cylinders, pads, and shoes and one brake hose. The left rear brake hose is a problem now, it is dirty and clogged up. Would it be best to replace the three other brake hoses and if so, where can I get them? NAPA, O'Reiley's, and Auto Zone don't carry rear brake hoses for '73 Mustang drums, and other places I've looked sell them for $33 at the lowest. Or should I try to clean out the hoses I have and put them back on?

 

brakes are to important to worry about saving a buck, buy new hoses.
