well here is a status on the worlds longest brake job!
I started in october.. and should have it done this week..haha.
lmc truck does carry the correct wheel cylinders, and was able to get the shoes (pr) at the parts store, all 3 pieces were $150.00! ouch!
Out of curiosity I checked an 80's 3/4 ton 2wd suburban that we have to see if the emergency brake cables would work. where they entered the backing plates was the same, so I might have to transfer some of the hardware from the frame to mount them, but I will be able to have e brakes.
my drums were too worn to turn, but with the amount that I will be ysing this truck, we decided that they should be ok af ter a goos scuffing with some 180 grit.
