M Crocker Posted September 25 Share Posted September 25 Hello, looking to see if someone can help me identify and hopefully send me in the right direction. to find some parts. i am working on the rear brakes on a 1956 Mack B-30 for a customer and all my resources are no longer available. I have located the casting #'s for the wheel Cylinder ( FD9570-472 ) I have Wagner Brake shoes and a casting # of ( FF 3510 ) on them. also not sure are the brake adjuster sold separately? any help would be appreciated M Crocker Quote Link to comment https://www.bigmacktrucks.com/topic/75986-1956-mack-b-30-hydraulic-brakes/ Share on other sites More sharing options...
Geoff Weeks Posted September 25 Share Posted September 25 Not sure what you are looking for? Your shoes look like they could be relined. Your cyl? they can be either be overhauled or sleeved and rebuilt. Parts like adjusters, often can be sourced by looking though buyers guides, although you need a good parts store who will have these catalogs and know how to look at them instead of a computer. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75986-1956-mack-b-30-hydraulic-brakes/#findComment-583408 Share on other sites More sharing options...

M Crocker Posted September 26 Author Share Posted September 26 Geoff Thank you for the information yes i know about having them relined and cyl. sleeved but it would be nice to know original part numbers and what the shoe are called for future people that may work on the truck. It looks like the biggest issue will be the adjusters. and spring kit . Thanks, again M Crocker Quote Link to comment https://www.bigmacktrucks.com/topic/75986-1956-mack-b-30-hydraulic-brakes/#findComment-583451 Share on other sites More sharing options...

M Crocker Posted September 26 Author Share Posted September 26 Geoff I forgot to mention you got it 100% right on looking parts up in the books in my area have one parts guy that is still from the time we looked parts up from a book sad part is he sold his business with all his books and he knew what the brakes were but when he went down to his old business to look them up in the books he found that they trough all them away.

Geoff Weeks Posted September 26 Share Posted September 26 (edited) Well you are dealing with something old and odd ball. If the adjusters are worn but serviceable, then they go back in, if they can't be cleaned up and serviceable, or the teeth on the wheel are badly worn, then you'll need a machine shop to copy the old parts, and make new. I have done that before, and as long as the machine shop is good, can be the best bet. I had to have a part made for an adjuster on my Saab, which has the hand brake on the front caliper. Grand total for 2 adjusters was $70. Other would swap out the front and rear brakes (caliper, disks and hardware) (requiring an axle swap on the rear, new parking brake cables etc) to "update" to the system that parts are available for. When working on old, not available stuff, you have to think outside the box, and keep in mind, that if it was made by man, it can be re-made by man. The type of machine shop you want is a small shop that does repairs on older stuff, not a large production shop. Ask if they do the kind of work you need or can recommend a shop that does. Your parts look "all there" so at least you have patterns to work from. Shoes can take linings, and cyl can be rebuilt.
