Dodge Repair/master cylinder rubber cup lip position


2001 dodge ram b2500 van 5.2L 318  v8 engine  115000 plus miles: Installing the rubber cups in a brake master-cyl.I need to verify if the rubber-cup lips on the secondary piston face in opposite directions or in the same directions.And if the master cyl.original equipment is a a.c.delco or other.

Hi Frankie Don,
Sorry but I don't have a manual for the rear wheel drive van. Probably the best source would be a dealer parts counter where you can see the internal parts of the master cylinder on the parts manual viewscreen and also by visualization see which cylinder you have there.
Good luck!
