Brake Part Identification Help

[my86m1009]

I just noticed a leak coming from some sort of valve in the middle right below the radiator, it looks like it feeds the front brakes. Mine is leaking and I would like to buy a new one but have no idea what its called.

That's the combination valve.

Proportioning valve.

You can always use the parts TM to identify any part that you can visually identify. GM or OEM part numbers are listed as well.

IIRC, the part you need is discontinued.

A search for the part number(listed in the parts TM), would get you more info.

Interesting and apropos to my dilemma of disappearing brake fluid in the rear circuit. This happened over the weekend. Could this valve have an internal leak, causing brake fluid to move from rear circuit to front?

Could, but doubtful, more likely a line or a wheel cylinder leaking

I agree, doubtful. The only other place those two circuits connect would be in the master cylinder.
