1. Check that the rear shoes are good.
2. Check for axel and wheel cylinder leaks
3. Check for proper setup of the rear drum configuration.
4. Check for proper adjustment of the rear brake system.
5. Check for a streched cable.
6. I belive there is an adjustment, never bothered with it on a fox because mine have always worked well.
Mine snapped shortly after that happened and I can find one at the auto stores, they keep giving me the wrong stuff, I need from the ebrake to the bracket it Ys
same with my stang. the ebrake has its attitudes, i just leave her in gear with the ebrake, but when i leave it running in neutral i have to 2 hand yank it. and with the AC, foxes have r-12 in it, so its really really expensive to charge it, you have to have your system flushed out and add some fittings to the top of your compresser and replace it all with r-134a. my friends dad owns a shop and i got it done for 25 bucks, but he took the cost of the freeon itself, which was like 83 dollars or something, and the 25 i paid was just in general labor. hope i helped.
Yeah my shifter cable thing sucks, the way i have it now, i cant actually get the tranny ALL the way into park, so if i dont put the ebrake on, the car will roll back in the driveway, but its halfway in so it will start grinding. So i have to make sure its there.
But i bring this ebrake thing up b/c i was changing rotors today and when i put the wheels back and and started tightening them the damn car started rolling, and i thought i had the ebrake on. kinda pissed me off.
I don't know about the '91 but my older Fox had a nut near the pivot of the hand brake. I adjusted it until I couldn't move the car on the 3rd click. You may need to remove the center console or at least some of it.
mine recently snapped, anyone know where to get a new one, ford? i was under there recently and it broke right as they go into the one cable, how would i repair it?
