Q: Disconnected battery cables to clean terminals and reconnected and now power assist not working.

asked by on March 27, 2018

I disconnected my battery cables to clean terminals and reconnected. I started the car and backed out my driveway and the brakes are not working properly. I have to press down hard to get the car to stop. The power assist is not working. Does the disconnecting the battery control the brake system?

My car has 140000 miles.
My car has an automatic transmission.
