It's on my 2006 Dually. The brakes pedal doesn't fully return after I release the brakes. It's an intermittent problem. If I lift up on the pedal it will stay up. It only stays down far enough to keep the brake lights on which generally isn't a big deal. It turns in to a big deal when I'm pulling a trailer with electric brakes. Any idea why the pedal isn't returning like it should?

Thanks,
Richard

 

You may just have a bad brake switch, I've gone through two, one wouldn't activate the lights the other would intermittently leave the lights on. I know on my brake pedal there is play for it to come up further, but I've never seen one fail in the sense of not returning enough, it's always been a bad brake switch at fault. If you haven't replaced the switch before make sure you follow the directions, you can only set them once.

 

I have the same issue with my 04.5 and my brother has it with his 2006. It is intermittent and it definitely is a problem with the pedal coming all the way back up after release. We both have adjustable pedals and fiddling around with those settings helped short term. I thought it might be a weakened spring. Is there a spring in the switch? How else would the pedal return when released?

 

I too had a similar problem. I put a return spring from the brake pedal arm to the bottom of the dash.

Your power steering reservoir may be pressurized because the cap failed to vent the pressure or steering hoses had flow restriction.
Check out the cap and may be drill a little hole on it.
