In retrospect I see there are specifically master cyls for 50 and 51. If this is a 51 master cyl and a 50 pickup is there a difference? I don't see it! | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 | Shouldn't make any difference if plumbed correctly.

Thanks, y'all are always on the $$. Just an observation wrt properly working brakes that you don't have to pump. Oh, so THAT'S what my brakes used to feel like!!!! Boy can my truck stop now  | | |
