Yes, I build up a fixture to bolt the wheel cylinder to, and use a 4-jaw chuck to align the bore with a last word dial indicator so I can enlarge it with a carbide boring tool. Then I press a stainless sleeve in, and bore and hone it to the proper diameter. Holes are then drilled in the sleeve to access the ports for the brake line and bleeder screw.
