Uneven braking
I have a problem with uneven braking on a new jet. One wheel locks up way before the other does. I have tried reducing pressure, but it has to be ridiculously low to avoid wheel lock. I have already ruined two tires.
I appreciate any ideas what to do about it.

RE: Uneven braking
If it is of the type of brake that uses an expanding O'ring, then you can use an O'ring lubricant, B.V.M. can sell you one.
This usually improves things and and helps to prevent the wheels locking under braking.
Ensure the brake lines to both wheels are the same length

RE: Uneven braking
Like Thomas said, you need to lube the o-rings in the brakes, but go to a store that sells pool supplies and buy a small tube or bottle of silicone o-ring lube.
If you lube the o-rings and still have a problem (and everything else in the system is OK), you can try placing an airline restrictor in the airline to both brakes (1 on each side). I usually place the restrictors just a couple of inches from the brake hub. This slows the activation of the brakes but does still allow full air pressure to them.

Also, how about 1. a proportional braking system as well (most electronic ones are) and 2. manually "pumping" the brakes to slow the jet down instead of just hitting the brakes and letting them stay on. A gyro will help keep the jet straight even with uneven braking.
