1992 Dodge Caravan Base 6 Cyl 3.00L

Brakes

Brake Master Cylinder, no brake pressure on the both rear drums

Replacing a brake master cylinder, the front disc brakes have a brake pressure, but the rear drums, no pressure at all. Wondered if there is a proportional valve because there are two brake lines run from the master cylinder .

Why don't you try bleeding the rears and see if fluid or air come out. This is a must when doing the master. Plus the master needs to be bench bled.

Thanks for the response, the master did bench bleed, but there is a combination valve, and it needs to have an insert tool to hold the movement of the hydraulic valve in order to bleed it. ( I saw it in you tube.com ).

It's sound weird, but in order to brake bleeding, the van wheels required to touch the ground, or on the ramp lifter.
