BTW, I have no fear of rebuilding wheel cylinders whatsover. Do keep in mind, if you do not have a brake hone to get all the rust out where the piston seals slide, you're wasting your time. When I did mine, I expected the wheel cylinder rebuild kit to be about $5 each and they were. Just for giggles, I also asked about price for NEW wheel cylinders which came with lifetime warranty and they were $11.99. So it was double the price, but I didn't have to question the bore size, didn't have to hone the cylinder, got a full warranty for as long as I own the truck and it was a no brainer. If that is the case with yours, just buy new wheel cylinders. There does come a point where you can hone them, and of course it takes a lot, but you hone them to much then your pistons and pistons seals will leak much sooner than later. Just consider it insurance and buy new wheel cylinders if they're under $15 each. Also get a new inner hub seal. That will help keep gear oil off your brake pads on the Full Floaters. Got any questions just ask !!!
Also notice how much meat was left on my brake shoes. I didn't replace those. I cleaned them good with brake clean as I did the brake hardware. Also lubed the adjuster with white lithium grease and made sure it moved freely throughout the whole threads. After the cleaning and dry, hit the brake shoe material with some medium to course sandpaper to sand off a layer of material giving a new surface of brake shoe. Don't breathe that dust. I also didn't see the need to have the drums turned since I didn't do a shoe replacement and they looked good with no hot spots, or grooves. I did also hit the drums with medium sandpaper too just to break down any glaze even though it didn't appear to have any. With seals, new wheel cylinders and 2 cans of break clean, back brakes were good as new for about $45 and no more adding brake fluid.
