Alright, I got a leaky wheel cylinder on my 14bolt. So I got to the parts store and find out there are 2 sizes. One with a bore of 15/16 and one with a bore of 1 3/16. At this time this vehicle is my only ride, is there a way to tell what size I have? I know the 14bolt is out of a 1 ton, and the bleeders on the current wheel cylinders are different sizes if that helps. Hope there is an easy way to tell. I'm buying a pint of brake fluid every week or two now . Oh its on a 88 jimmy with a 10bolt front, and if there is no way to find out with out taking the wheel cylinders off, should I buy 2 of the big bore ones or 2 of the smaller bore ones.
