Lets here what you have other than 715s!
Brian , The 3 lever light switch has a circuit breraker inside of it. That is the only type of fuse protection that the electrical system has. You must have a short somewhere.
Need more information about your brake set up. Did it work before or did you just install it ?? Stock 4 wheel drum brakes ??
If your using a disc / drum master cylinder ( 89 waggy ) , and drum / drum stock brakes, your going to need a 10 psi residual valve in the front line. M1028
Steering joint easy fix...
Barry's diagnosis sounds good to me. Those valves are available at most big aftermarket places (summit, speedway, jeg's, etc.) as well as the disc brake places like masterpower.

Late model steering shaft install, maybe column too
under closer inspection earlier today i found the source of the short which was causing the breaker to keep popping. its the brake light switch. both of these problems (the short and the front brakes not working) occured almost at the exact same time. the brake light switch is hydrualic and is located in the front brake line.
could these 2 problems be related? or is it some strange coincidence?
thanks
