Small Engines (Lawn Mowers, etc.): John Deere STX38 brakes and mower deck, john deere stx38, draft arm

Question
How do I adjust the brakes? Now it won't stop at all.
Also, how can I fix the deck so that it doesn't "jump off" the back slides every time I hit an ant bed or turn sharp?

Answer
The brake problem is easy.  Find the brake caliper, it will be behind the right tire.  Tighten the nut in the center to adjust the brakes.

To keep the deck from falling off.  Follow this solution from Deere.  I know, it's confusing.  It would be way worse if I tried to explain it.
