Old Lehman questions

[Ruffrider]

Hello Folks I just traded for an 97 1500 with Leman conversion. I have most of the plastic removed to check things out. The emergency brake does not hold squat how do i adjust it? The rear axle is solid with air shocks on it the air pump on the 1500 does not move the backend at all but builds pressue on gauge i am thinking of running a separate tee with an air fitting. what size brakes go on the rear axle and can i source them locally? thats next!!! well rear hatch will not latch, think i can adjust that PO had it taped shut well thats a long 2nd post but shouls do it for now.

Thanks, Ralph

You might get more responses in the Lehman section.I'm going to guess it has drum brakes and that they will be from either a pinto,mustang or ranger.I would pull the drums and make sure everything is assembled and adjusted correctly.There are several Lehman owners here and hopefully one of them will see your post and respond with more info.

Can someone with a higher pay grade move this to the Lehman area and rename it. I don't have that ability. :xzqxz:

Take your brake shoes to a NAPA auto parts store and see if they can match them to something. It was very common back in the day to use Mustang II rear end brakes

Where is the air going? What is the air gauge reading from?

Brake shoes ... 9" Ford Drum Brakes ... Some numbers to help guide you. Most of it is like late '70s or early '80 Ford Pinto, Mustang II, etc. Even up into the '90s Ford used a lot of 9" drum brakes on cars. Your rear axle is a 6.75" integral carrier rear with a stamp steel rear inspection plate, but they came with one of two different gaskets, square looks like a square with 4 rounded corners, octagonal has 8 sides, no curves. Keep in mind that these numbers are from the latest GTL book I had, Many will need to be cross referenced.

You can experiment with other rear wheel cylinders too, Ford made them in several diameters. Bigger will increase braking force while decreasing effort but increases travel, smaller will decrease brake force requiring more effort but decreases travel. It's a balancing act, I played with them but in the end, went back to the sizes as Lehman used.
