I have a 1993 Geo Metro Hatchback. I have a mechanic friend working on the rear brakes. He says I need a proportioning valve, but when I look it up that is something different. It is a small rectangle 2/5" long with two tips sticking out each side the rear brake hoses attach to it. What is it called and where can I find it?
1993 Geo rear brake. Is it the Proportioning and Differential
