1973 plymouth RR. car runs and drives great now but the brakes are very sensitive with little to no pressure on the pedal the front brakes will lock up would a booster that is going bad cause this? Car has sat for sometime before I started working on it for the original owner , nothing is leaking by the wheels ie calipers or wheel cylinders.
Have you made any changes/repairs to the brake system? were any changes made to the brake system when it was parked?, is/was this a prior problem?...just like to ask before the "ghost" chasing starts
