just had a mechanic/shop install new master cylinder and hoses on my big rig, and thought I was going to have brakes for awhile. Not true ! They lasted about 2 days (with alot of pumping) then I lost all pedal along with the brake fluid in the cylinder. I paid alot to have so little done. Anyway, he said I probably need a complete overhaul of the brakes at the hubs. Does that sound about right ? I will if it requires it but hauling this big 2 ton rig around on a wrecker is pretty expensive

Thanks, Troy
