95 pete 379 cruise control problem

Check the brake switch.

 

I had the same problem 2 weeks ago. It look like a brake switch, but it a cruise control switch which knocks off the cruise control when you applied the brakes. Its under the dash, behind the ignition switch. You have to remove the bottom half of the steering column "cover" which is about 6 screws or so. Then look underneath(behind the ignition switch) and you will see 2 wires hook on a round switch. Remove the 2 little screw from the wire and use some channel lock pliers to remove the switch counter clockwise. It easy and self explanortory was you see it. I've replace 2 of them in two years. Only mine started leaking air.

 

I think it costs around 20 bucks, the last one I replaced, The broker I haul for in regular basis told me to ask the shop and they gave me one. Im surprise yours aint leaking yet, Cause mine cruise stop working then started working again then it started leaking air.

 

Also try pulling the brake and clutch pedal up with ur foot. I have to do that with my truck sometimes

 

The brake switch is on the floor behind the steering column. You have to remove the kick panel to get to it. It screws into the air manifold, and will have a couple of wires connected to the top or side of it.
