How do you Replace wheel cylinder 1993 ford ranger?

...remove brake drum, shoe and parking brake attachment... remove springs with special brake spring removal/installation tool... you may need new drums or resurfacing.., also new drum brake hardware (i.e. springs)... when you have all the springs off you can see the wheel cylinder on the north portion of the back drum.., remove it by first loosening the brake fitting to the cylinder using a 7/16" Flare Nut Wrench... then remove the cylinder mounting bolts located on both sides of the bleeder screw... reinstall... make sure to spray brakes with brake cleaner before and after service... Enjoy! (you may also want to invest in a large SOFT hammer to get the drums off)
