I have a 1970 cord with a 302 ford engine, automatic, drum brakes, power steering, and I'm installing power brakes but keeping the drum brakes. I have installed the booster and brake master cylinder, and bled the brakes. My problem is that after bleeding the brakes, I have at least 4 inches of play in my brake peddle. The peddle gets hard , but not until you push about 4 inches. I measured and installed the booster so that I have the brake peddle in the same place as before. I check the vacuum and the booster is getting vacuum. Is there any difference on bleeding power brakes than nonpower brakes? {black}:idontknow:
Well most boosters have a rod that's adjustable so you can adjust the rod to take a play. They're not made all exactly the same. That's why there's the adjusted rod so you can take up slack. If that doesn't work then you got a bad booster or somehow you got air in the brake system when you did the job if you disconnected the lines to the booster.
