I bought a brake controller that uses a sensor in the brake line. Today, I

thought.

Well, as soon as I started the truck, the brake warning light came on. So I
had the better half pump the brakes while I bled a whole can through the
front wheels. No joy.

I called "the Kid". He said to get a vacuum device from bumper bumper for
only $20. Well, it was $50. But I got it and bled a can through each front
wheel. No sign of bubbles at all. Note: the sensor is on the front set on
the tandem brakes

Still no joy. I got a brake warning light. I just got ****ed and called it a
day. What do I do tomorrow?

If this 93 has ANY type of ABS you can forget about using a tapped line
for the brake controller. The sensor shows up as a leak to the computer.

Even if it doesn't have ABS it is likely that the sensor has a weaker
spring than the switch in the line which senses brake failure and trips
the light.

These are why nobody uses them any longer. They cause a LOT of problems
in modern braking systems.

Plus the better electronic models do as good if not a better job, and
they are easier to install. Just make sure they are level.
