rear brakes leaking from unknown unit above drive shaft 1999 S10

Asked by jballn33 Feb 02, 2015 at 11:18 AM about the 1999 Chevrolet S-10 LS Xtreme Extended Cab RWD

Question type: Maintenance & Repair

I have a 1999 Chevy S10 Xtreme 4.3L rear wheel drive that the breaks are leaking. It is
coming from a unit located above the rear drivers side drive shaft and tucked next to the
frame and bed. hard to access and i do not know what it is to replace it. i have found that
it is possibly called the DRP valve but when i search for parts or info i come up with
nothing so i am at a loss on how to proceed.

Pretty sure that is the Dynamic Proportioning Valve. Regulates the rear brake pressure in relation to the front brake pressure.
