rear brakes leaking from unknown unit above drive shaft 1999 S10

Asked by Feb 02, 2015 at 11:18 AM about the 1999 Chevrolet S-10 2 Dr LS Xtreme Extended Cab SB

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.

ebay has some brake proportioning valves for s10. check them out and see if they look like your part.
