I'm in the process of installing a power booster and master cylinder. (1967 Chevelle) So far I've bolted the new booster to the firewall and hooked up the clevis to the bottom hole of the brake pedal. My question is, the brake pedal is lower to the floor than before. Is this normal. I have the clevis adjusted out as far as it will go without coming off the rod. I also read some post about making a new striker plate for the brake light switch. Mine looks like all I have to do is screw it in a little farther to make contact with the pedal bar since it is lower and it will work. Is that okay??. My other question is the spring that was connected to the brake pedal to pull the pedal back up. Is this still needed. It doesn't appear that it is. I just don't want to go any further and have to take everything apart again. I've did alot of searching for the answer to these questions, but none talk about these issues. Can some please help. Thanks in advance.
