Bunkerbuilder - Thanks for your posts. I suppose I could remove my rear proportioning valve, however after fabricating the longer arm and clocking the valve with the dot at 12:00 with no load in the bed, my truck will stop on a dime, going forward or in reverse. I could not be more happy with...

I explained this in detail in post #75 of my rebuild thread. There are two things that you should pay attention to - 1.)- the little dot on the valve needs to be positioned at 12:00 with no weight in the truck, and 2.)- the angle of the two actuating arms needs to be at or close to 90 degrees...

I stayed with original fluid. The rear disc brakes have been on my truck for three years now and are still performing flawlessly. The parking brake works as designed and holds the truck without any strain on the transmission. Of all the modifications and improvements I did on my M1028, in...

I am currently in the process of lifting my M1028 5" and am improvising an adjustable linkage for the prportioning valve. I will post photos when I get this done.

I have had my TSM rear brake conversion installed for several months and am still amazed at the braking power. Even backing downhill, the rear brakes do not grab the way the drum brakes did. Without a doubt, one of the best modifications available for the M pickups.

My M1028 does indeed have the factory load-proportioning valve. I didn't touch it and everything works perfect. The only time this would need to be modified is if the truck was lifted.

The kit on Pirate has calipers without emergency brakes. The calipers from TSM are rebuilt '77 Eldorado Cadillac with emergency brakes. Also, the Pirate kit uses rubber hoses, and the TSM kit provides flexible Stainless Steel lines with mounting tabs.

It should. Give the folks at TSM a call.

It was really surprising how easy it installed. The only hitch was the tabs that hold the SS flexible lines had to be welded to the rear of the perch. Other than that, it was simply bolt-on. The braking power is now stronger and consistent, with a full, firm pedal.

When I received my M1028 the rear brakes were grabbing bad, so I pulled the rear drums to inspect. The drums and shoes looked like the surface of the moon, and my mechanic determined that the drums were too severly de-faced to be turned. The cost of new drums, shoes, and the other items was over...
