Maby I can help. First of all it would help if you will pull the dash out and take a look at the pucks in the master cylinders and be sure that both pucks are flush with the face of the master cylinder. If not make necessary adjustment to the push rods to insure they are. Some older models would bend the tab that the push rod passes through and hold the brake on enough and not let fluid back into the master cylinder. If this is the case the tab will have to be bent back into place with a pair of vice grip plyers. The next thing would be the bleeding procedure. You will notice that the master cylinders lean backwards so try jacking up the rear of the vehicle until the master cylinders are level then the cylinders should bleed by simply pumping the handle bar on that side and it will bleed the air back through the master cylinder. Be sure and use dot 5 silicone fluid. If these items do not work then there could be a problem with the master cylinder or caliper. Hope this helps, it has done the job for me many times. Good luck and have a good day.
