brake problems
ive been having some problems with my 93's brakes.
first problem: the brake bias is mostly in the rear. ill step on the brake and the rear tires will lock up before i feel any type of body moving forward, actual stopping power.
second problem: the brake(s) stick on from a stop. today we took the truck with 400lbs of garbage to the dump. asfter we got gas down the road my dad stalled the truck 4 times in the station parking lot. then to defend himself he said it felt like the brakes stuck on. so when we got home i took the truck for a quick drive and he was right. something, wether it be the parking brake or the driving brakes, sticks on when you go to take off. i mean on flat, level ground from 20mph the truck will slow itself down pretty quick whith the clutch depressed and the transmission in neutral.
any advice appreciated.

Sounds like a sticking front caliper. If thats the case take a ride around the block and come back and check which side of the truck the hubs are the hottest from the dragging caliper. Or could be a bad master cylinder

I doubt it's a bad caliper, because the truck would pull hard to one side and you would definitely notice it. I also doubt it's a master cylinder, because they just don't fail this way.
What it sounds like to me is the RABS module is gummed up and isn't allowing the rear shoes to be pulled back after you apply the brakes. It's a very common problem on ford trucks of this vintage. VERY common.
The fix is either to buy a new RABS valve, or (I prefer this one) replace the valve with a piece of brake line. Bleed the system out well, pull the dash bulb, and pull the ABS fuse. The RABS system is a joke and barely works when it's working right. It causes far more problems than it solves and you are better off without it IMO.

as far as the brake bias issue i have no idea. i understand that since there is no weight in the bed if you hit the brakes hard its gonna slide bu it slides before it slows.
and about the RABS module, it dosent have one. i traced the brake lines and nothing. also, the ABS light is always on and when when i say the rear end slides, the tires lock up and slide down the road.

Why would you have an ABS light with no ABS module?
