Re: All drums and no hope.
You need to make darn sure the brakes are adjusted. If in doubt adjust the shoes to where the drum/spindle or axle is tight, and barely turns. You can back the shoes off later....to operate vehicle...
Fill the M/cylinder, let each wheel gravity bleed, one wheel at a time, of course do both rears or both fronts together...THEN have someone help you pressure bleed the brakes...DO NOT LET THE MASTER CYLINDER RUN DRY!!! the master cylinder needs to be bench bled first... I use 1/4" I.D. clear vinyl tubing, I loop it a foot or two above the bleeder screw, so I can wattch for fluid and/or bubbles...I use an empty 16 oz or larger plastic pop bottle to catch the excess fluid. I drill a hole just slightyl smaller than the OD of the hose, so the tubing stays in the bottle. and you need another small hole in the bottle cap for pressure relief... |

Re: All drums and no hope.
-Master Cylinder (bench bled twice)
-Both 3/16th lines to the front. -Both front hoses. - All 4 wheel cylinders, shoes, springs, drums, self-adjusters - 5 foot section of line going to the rear hose. - Rear hose - Both 3/16th lines going to the rear. I seem to keep getting air in the system so I installed 4 speed bleeders. The pedal will start to get firm and just go away. I can hear the shoes hitting the drums..both front wheels you can hear the shoes dragging the drum very slightly. I never considered adjusting them?
