Thanks! I'm swapping over to a 1970s C10 dual master cylinder -- NAPA M1880 and O'reilly actually had the wheel cylinders in stock for $38/each.

I pulled out the old brake tees and those cleaned up pretty nice to be reused. I was going to try and salvage the front lines (seemed to not be original) but now I think it's going to just be easier to replace them.

Haven't gotten to the rear brakes yet, but suspect those will take the same R&R as the fronts. I suppose I'll pick up another set of jackstands so that I can pull those apart and see if any of those shoes need to be replaced. (3) of the front shoes measure 3/16" of lining remaining -- I compared it to a new NAPA shoe (that was the wrong size) and they only had 1/4" of material.

I'm going to make another thread in a couple of days on towing, but... has anyone ever towed with one of these with the 235? I only tow my boat 1-mile @ 25mph but I'd like to do it with this truck. The boat trailer has dual axles, dual brakes and weighs about 6500lbs.
