Darn micro converters!

[rjewkes]

Darn those micro converter Malfunctions. I rewired my truck with a brand new harness out of the junk yard donor. And in the process got everything working. Including the Dilithium Crystal Crack&Fracture warning light. Explains a few problems i have had with my brakes.

Are you talking about the little red light that says brakes?
Becuase it comes on when ever your brakes lose presure in the system from one side or the other or both sides. And recentering it Can Be a pita!

Check Your Master Cylinder. Try bleeding your brakes or IIRC, Low fluid that is fluid levels lower than a 1/4" from the top of the cylinder body can cuase this. you may do as th book says, bring fluid up to correct level and turn the key to on but not running. put the cap back on and then with the key still on depress the pedal it should self recenter. I have only seen it self recenter twice in 8 yrs of experiance with this system.

Good luck and get her done.

tried the bleeding and did not work. and does not look like a releif valve in site to just let some out.

Here's what the manual says as an example of how the valve works:

Should a failure of the rear brake system occur, hydraulic fluid pressure in the rear brake system would drop. During brake pedal operation, the fluid pressure buildup of the front brake system would force the differential valve toward the low pressure area (secondary system outlet port). Movement of the differential valve forces the switchy plunger upward over the taper shoulder to close the switch electrical contacts and lights the warning lamp, signaling a brake system failure.

...and here's how it describes the proper procedure for centering the valve:

Turn the ignition switch to the ACC or ON position. Loosen the pressure differential valve inlet tube nut of the unfailed system, or the side opposite the system that was bled last. Operate the brake pedal carefully and gradually until the pressure differential valve is returned to a centralized position and the brake warning light goes out. Tighten the tube nut.

Hope this helps...and since this thread is about brakes, it's getting moved to the appropriate topic.

thanks guys.
