85 C20 Heavy Duty Options, Questions..

[1972C10]

My 85 has a Load Control valve on the frame that has a bar that goes to the rearend that i assume gives the rear more braking based off how much the truck is squatted ..

I belive its bad As my brake light has been coming on latley and sometimes the brakes feel vauge The front is all new but the back is questionable.

Im going to get some new wheel cylinders as i suspect mine are leaking but ive yet to find a place that can get that load control valve.

I recall someone saying to take it off Is it as simple as that? Would the prop valve up front be different becuase of the load control?



Also does anyone have a schematic for the Accesory cooling fan ? Im trying to get it working properly and cant seem to find any info on it I belive it comes on based off the A/C Being on .. Or the engine getting hot.

I think 85 454 trucks were the only ones available with this Althou Im not sure But it is the only year truck that they have a fan switch listed for in LMC.

If anyone can tell me the color of the wires going to the coolant sensor on the passenger side that would more than likley get it fixed up .


Thanks In Advance
