Hard brake pedal
Have a 90 C4 that has been basically parked for over a year. Started, moved out of the garage and back in twice over that time. Pedal is at the top but car rolls easy. What may be problem and is there any temporary relief?

Start the car put your Foot on the Brake Pedal Listen for a Vacuum Hiss if you hear it the Booster is most likely bad, You may also want to with car running remove the Vacuum Hose on the Booster and confirm you have a Strong Suction and that a Rodent has not chewed the hose or it didn't crack or break
