Hi everyone. I just bolted up my rebuilt power brake booster and went to fit the new master cylinder. The new master cylinder is a dual reservoir one for all drum brakes and is suppose to fit my application. I couldn't get it to bolt up. There is a rod that comes out of the booster and is seated as deep in the booster as it will go. Its about 4.5 inches or so long. The only movement with this rod would be forward. I looked at the back of the new mc and where the rod would hit, the indentation/slot is only about 1/2 inch deep. Looked at the old one and the same area is about 1 3/4 inch deep. I tried the old one again and it bolted up fine. Should I be looking for a shorter booster rod/plunger if in fact they even make one??? I bought the mc sometime ago and don't know if it is returnable. The old one, where the rod makes contact (plunger), is 1" in diameter. The new one is 1 1/8" in diameter.
There are 2 pics to look at. Any suggestions would be appreciated. Thank you, Carmine.
