Can you feel when the pushrod engages by pressing the brake pedal? I think I need to lengthen the pushrod for the new master, their is no fluid and no lines connected. The master is bolted to the booster with the original push rod. If I press the pedal it depresses maybe two inches and then I can feel it hit a wall and have some tension as it continues to depress. I would assume that the first two inches of the pedal depressing means the pushrod is too short and it has to take up the slack before engaging the push rod. Thoughts?
