A few years ago upon completion of my 70 Coronet I decided to put aftermarket front disc brakes on it. I still have drum brakes on the rear. After installing the front disc brakes, the car is nearly impossible to stop! I have bled and re-bled the brake lines several times. So it must be something else! Included with the disc brake kit was an inline increase/decrease valve, in which I have no clue where it goes, as there were no instructions as to installing it. Do I need to install it? My car did not come with power brakes, and I have not tried installing a brake booster yet. Can anyone please tell me where this increase/decrease valve goes? Thanks for any and all replies!
