Review on Optimize Braking Performance with GM Genuine Parts 19244448 Brake Proportioning Valve by Jamie Rogers

I noticed brake fluid on the garage floor so I took the car in to have it checked. The technician said liquid was leaking from a small tube at the fracture line and explained that he had no idea what those parts were. He said he would call the dealer and then come back with me. I quit tech and went home and opened my ALLDATA program which I bought for my car because I keep maintenance items like water pump, radiator, thermostat etc. I could tell my car had two of these on the fault line. I looked up the part number and none of the local parts stores had it. Needless to say my trusty AMAZON had them and I had them in two days. The problem is solved! Miss Toni
