I found a brake fluid spot on the driveway from my 70 chall,after a long search I found fluid leaking from what I presume to be the proportion valve or parts there of,it is the small brass block that divides the two front brake lines,the thing that is leaking is a little valve dohiky that sits under this block,you can push this little prong in and out a smidgen and feel the thing is all wet,does any one know what this valve does,if it does nothing I will just braze it up to stop it piddling on my garage floor.
