Re: Hard break pedal
Check for vacuum at power booster, open the hood and look and listen , do you hear a hissing noise, repair it does the engine run abnormally rough , possibly from the hissing by now it should have set a code p0171 lean exhaust if you do not hear a vacuum leak or service engine light is not on you will probably have to replace the power booster.

The most obvious cause for a hard pedal is simply not enough vacuum. Check the brake power booster by pumping on the brake pedal while the car isn't running. Continue pumping until you've "bled off" the vacuum from the booster. Hold the pedal down while you start the car. The pedal should go down a bit more beneath your foot. If it doesn't, then you should examine the connection between the vacuum hose of the brake power and the engine's vacuum.
Replace the brake power booster if the connection's fine, which would fix the hard brake pedal problem.
It may be your calipers need replaced. Check them for signs of wear. Look at the metal spring where the brake pads sit.
Apply tension to the pad and see whether you hear a pop. If you do, the brake pad is moving too much on the bracket. Replace the caliper. This could help the hard brake pedal.
Yes and no. No if it is still working you probably did not break anything for now. Yes the damage you did will probably shorten the life of the transmission. You might want to drain the trans fluid to see if you have any large pieces of metal floating around. I would not change the filter if the trans has never been serviced.
The brake light switch on these trucks was a poor design. Its mounted on the brake pedal. Look under there and bend the bracket that holds the brake light switch slightly and things will start working again. When these were new we used to just grab the brake pedal and pull it toward the drivers seat really hard and let go. This fixed your problem 99% of the time.
