All the brakes are new as with the master and no leaks. Everything is new except the booster. The brake kit came with a new booster but it was one of thos eones that stick out from the firewall. So I elected to use the old booster. Here is where it gets stupid. I'm pretty sure the booster is bad or has an internal leak. When I fired the 440 up in the satellite it sucked the brake pedal to the floor. I assume the booster is shot. Has anyone ever had a booster do this?
