Do i have 7/8" wheel cylinders? what brand for new ones?
I have a leaky wheel cylinder...i need to replace them. id like to use the small ones for quicker action so if they are 7/8" ill keep using that size. also, is there a brand that is better than another?

Do the GM wheel cylinder upgrade, brakes that work well are way better than "quick" what ever that is supposed to be. The only thing you will get by staying with the smaller wheel cylinder is less braking power and these trucks need more brake.

I am just going by what I can read because ive never messed with wheel cylinders before... here's a quote from Philip. And by "quick" i believe that means having the movement of the brake shoes happening faster, or locking up the wheels at the same time as the front discs.
The larger wheel cylinders will slow down the apply time of the rear brakes. You have more bore volume to fill to get the same apply pressure as the smaller cylinders.
I use the small cylinders on my dually W350. I can lock the duals at will if needed. The 1" bore cylinders wouldn't.

An example as quoted above; the hydraulic bottle jack works on a small piston filling a big cylinder for more mechanical advantage over a bigger version. Heck, you could probably put 2 inch wheel cylinders in the rear and never have to replace the rear brake shoes for the rest of the life of the truck. You however would then be going through regular short intervals of replacing the front brakes and rotors as they would then be doing all of the stopping effort...
