Re: Disc Brake Upgrade Reference Thread

Some of the master cylinders on the 3/4 tons will be different than a 1/2 ton master, depending on the factory brake package. If your front calipers have the 2-15/16" bore, you can likely get away with that '79 K10 booster and master. If you have the 3-5/32" bore calipers, I would suggest a appropriate master. The masters will interchange with boosters regardless of 1/2 ton or 3/4 ton, at least with pre '99 trucks.

Should I try and find a booster & master cylinder off a 3/4 ton, or will I be fine?
