i had a similar problem on a vehicle. turned out the master cylinder was wrong for the car. the dept of the rear of the master cylinder where the brake booster rod goes was deeper than the original. drove me crazy for a week. i thought it was trapped air. Remove the master cylinder and measure the dept of the rear hole. Now measure the extending rod end from the booster where the master cylinder will bolt on. it should be real close. check your manuel for the exact measurment needed. most booster rods have a adjustment on the end to lengthen or shorten them. mine was off darn near 1/2"
