Re: '93 GC Front Brake Problem
On the TJ you can pull two fuses to disable the ABS system.
This works well for off roading and gives the TJ half a chance against
those 'Jeep eating' trees.
I don't know if that changes the symptoms or not.

Re: '93 GC Front Brake Problem
Mike, I know of two relays inside the Power Distribution Center on the
passenger-side in the engine compartment that can be pulled to disable
the TJ's ABS as I did when I swapped in my Dana 44, but I don't think
there are any fuses specifically for the ABS system. At least I never
found them when I was looking for how to disable the ABS.

You are very likely right about two relays instead of fuses. My old
