Again.......After driving the Impala for a couple years and getting used to the Brakes as they were......I just accepted the Braking system as it was.......After getting other people who are a lot "Smarter" than me involved to resolve this issue......It was recommended to install a Hydro-Boost system in the car which uses the Power Steering pump and fluid as a power source.....Just got the car back with the new system installed....OMG!!!........I love the car again........I will never use a Vacuum system again.......I never anticipated the Brake stopping power the car really had......
