The proportioning valve on my 74 Roadrunner was gunked up pretty badly after sitting for three years and I got a replacement from a wrecked car, but I was wondering if there's a test to make sure it's good? I can blow air through the holes. The front hole allows air to go to the holes for the front brakes, and the rear hole allows air to go to the hole for the rear brakes, so if air is getting through does that mean fluid will?
