I have 4 wheel manual drum. I just replaced the rear wheel cylinders, removed and cleaned the outside of the original brake lines.
I cannot get any brake fluid to the rear. I have tried a vacuum pump with no luck. I have had my daughter pump the brake pedal and I can hear air...
Converted to front discs, have the original front brakes complete from Spindle to drums, including the Drum/Drum Master cylinder collecting dust in my garage. I can send pics if interested.
Make me an offer.....send a PM
