Hi new guy,
Kent's suggestions are right on the mark.
These old trucks are quite simple in design so anyone with moderate mechanical ability should be able to successfully perform most maintenance/rebuild tasks. If your mechanic's mechanical abilities match his spelling/penmanship abilities, I would bet you could do a better job anyway. Given its age, definitely replace ALL of the metal brake lines. The 3 brake hoses are a very common part (I believe that is the correct part number on the invoice), and even many of the wheel cylinders and master cylinder can be sourced new. Resleeving your original master cylinder and wheel cylinders is the best remedy as they will last longer as previously mentioned. Replacement brake drums are non-existent for big trucks so don't have them surfaced unless absolutely necessary. Often a good sanding with a jitterbug sander will do a suitable job of removing accumulated rust. Finding a shop that can reline your shoes may take some searching, but there are still places that do the work. Try to find a place that works on larger trucks as they may provide a lead.
One must hone their parts hunting skills in order to own and work on old relics like these. You can do it!
Good luck, and cool truck!
Paul
