with the car off hold the brake pedal down. then start the car. the pedal should go down more if the booster is working. rick i have a 79 dodge and am trying to decide if i need a new brake booster for it or not. brakes are working but have to use very hard foot pressure to get them to work as they should. driven a 75 and 80 models and dont remember either of those needing that much effort. could be hoses too but havent gotten that far yet just wonering if there was a way to check the booster or not. .
