First, I have to say I haven't noticed anything wrong with the truck. It stops the way it always has (terribly), and powers through 20" of snow like it's bare asphalt.
However, yesterday I just happened to look at my reflection in the window as I was about to pull away and I noticed the right rear tire was spinning while I had the brake on.
Here's the scenario - I was partially pulled up onto a huge snow bank to get out of traffic, so the rear tire had very little traction. The hubs were locked, but in 2WD at this point.
• When in park, rear wheel does not spin.
• When in drive or reverse, with foot on the brake, wheel spins. Quickly, not slowly - there is no resistance at all from the brakes.
• In neutral, wheel does not spin (obviously)
• When in drive, with brakes on, wheel is spinning, but as soon as I engage 4WD, which was not pleasant and probably a mistake in hindsight, the wheel stopped spinning. Which makes even less sense to me since the wheel with the least traction should get the power right?
I live in Minnesota, and my truck doesn't fit in my garage, so I have limited ability to diagnose this with all the snow and ice in my driveway, but I can probably get it on jack stands. I would like to get your thoughts though. I do have an OME lift, which I've heard can affect the proportioning valve. If I'm honest, I wouldn't be surprised if there was zero braking power on the rear wheels - that's how well it stops. I don't think the pads are bad, but I can check - however they were all replaced at the same time and the fronts are still fine. Even bad pads should still grip a wheel though.
I'm thinking it could be one of the following:
• Need adjustment to prop valve
• Need new brake lines because there's a blockage to the rear
• Need new master cylinder - pedal is not soft though
• Something I'm not thinking of
How would go you about deciding which of these it might be? I have a video if you really want to see it.
