Harlan,
 
You must have lost a ground while under the dash. Find it and you should solve 
the gas gauge problem.
As for the brakes, where the booster and master cylinder both off the grand 
prix? On the booster there is a shaft. They can be short or long. They don't 
mix and match. A long shaft in a shallow master cylinder can be an issue.
Also when switching from manual to power, you need to move the pin in the brake 
pedal to the other hole. If I remember correctly, move to the top hole, but 
either way, the OTHER hole.

Subject: [Chevelle-list] brakes/fuel gauge

i put power discs in my 68 from a 1969 pontiac grand prix, and now i have to 
use both feet to stop the car and the stopping distance is great, can anyone 
help to what might be the problem? seems like they are working because the 
rotors get warm after a drive.

and also the fuel gauge is pegged on full at all times


thanks!
Harlan
