Review on Optimize Braking Performance with GM Genuine Parts 19244448 Brake Proportioning Valve by Michael Willis

I replaced them with a 1995 Buick LeSabre that I have owned for several years. I fixed the rear brake hoses and decided I should just replace them. The brakes have never been right since I've owned the car. They always felt a bit spongy, even though I bled the brakes, and the anti-lock brakes acted weird at times - sometimes the pedal was higher than other times. After I replaced them and bled the brakes again, everything was fine. The brakes work great. These blocks look different than the original blocks on the car, but function and fit the same.
