Recently, I installed Hawk HP Plus pads on my '86. Soon after, I noticed that when the car was cold, the pedal would require more pressure to brake. When warm, it operated perfectly. Now, it seems like the brake booster is entirely gone. Really hard pedal- a lot of pressure required to brake, and it is pretty much constant with occasions in which is works fine (5-10 percent of the time).

Does anyone know where I should start? Vacuum lines? Booster itself?

I an extremely busy and it is my only operational car. I need to drive it around all day, so I don't have all the time in the world to tear it apart.

I hope the Rex gurus can help.
