Does anyone have a exploded view of the front brakes for the M37? Maybe a DIY for a swap?


Thanks alot guys

These might help.

Great, Thanks! Seems fairly straight forward. Pardon my ignorance but Do I have to take the hubs apart to get the drums off? I really have never worked on a 4x4 drum front end and I would like to get some tech in order before I jump in to rebuild these wheel cylinders

No, you don't have to disassemble the hubs to get the drums off. If they haven't been off in a long time, though, they can be a real bear. There is a straight-slotted screw which holds the drum to the hub and can be a real b!tch to remove, but it has to come out first. After that, the drum comes off just like any other drum. It may require considerably more muscle with the BFH before it comes off, but it will come off eventually. Watch out when it does come off, too. It will be heavy!

"BFH" = "Big Freakin' Hammer"

Word of caution: issue ear plugs to any innocent bystanders of the female persuasion (or under the tender age of 35 if male) so that you don't improve their vocabulary or tarnish your own image in their minds.

Lifer is on target as usual, no need to disassemble the hubs unless the intent is to clean and repack the wheel bearings, which is not a bad idea while the truck is in the air and front end brake work is being done.

While trying to remove the slotted head screws that retain the drum, if they are stuck, resist the temptation to take a center punch and BFH to them. They will come out using conventional methods like penetrating oil, heat or impact gun.

Ear plugs, I get them by the 100 count box and there have been times when I would have had to issue them to everyone in my neighborhood. M37 work can be frustrating but very rewarding.

Hahaha! Ok thanks a Million - Ill try to get them fronts changed this week! Is there any *Good* source for wheel cylinder rebuild kits?

I replace the wheel cyls when needed, however a search turned up this discussion,
and several others, on the rebuild vs. replace and sources topics.
