Coach drifts with parking brake

2000 Intrigue, 36 ft, Cummins 350

I have put 35,000 miles (current total 104K) on this coach. This may have happened many or every time I break but I have only noticed this twice. I park, put the parking break on and level for the night. My camp site is fairly level. In the morning the coach has moved forward 4-6 inches. I have also parked many times on a grade in front of my home, not leveled. In the morning if there was any serious drift I would have noticed but I did not look for any drift neither did I notice any. When I shut down the engine I will go from 110 pounds of air to maybe 80-90 over night every time but stay level.

Any thoughts might might be causing this?

Ours doesn't. The way I see it, you might need to get all brakes adjusted. It's an easy process, any chassis shops can do it.

If it's moving after you have set the parking brake, the brakes are out of adjustment or it time for brake shoe replacement.

Loss of air pressure should not affect parking brake. Parking brake actually takes air pressure from the brakes and allows the springs inside the brake chamber to fully apply the brake. If the brakes are out of adjustment, it will not be able to apply sufficient pressure to hold the coach still. This will also prevent you from stopping the coach in a panic or down hill situation also.

It's a very simple procedure and any truck shop or service center should be able to take care of it for you. If you were closer, I could teach you in about 15 minutes.

It goes without saying, do not put this off, get it taken care up asap. I would throw a chock under the wheels in the mean time just to be safe.

You know how to contact me if you need more info.

Are all tires moving it just the rear tires ?

It could just be the axle sliding foward due to the arc of the suspension.

With the jacks on the ground, the chassis can't move.

If your leveling system is taking too much weight off the rear tires, then your brakes are not able to do their job and keep the bus from moving. Leveling jacks are not brakes - they will slide, especially on grass or gravel.

That coach does not have jacks.

Air leveling on his coach.

OP have you done the DOT Pre-trip Air Brake test recently?

A portion of that test, will test if your Park Brake is working correctly.

If the coach doesn't have jacks or leveling stands, then the brakes need IMMEDIATE attention. The parking brakes work on the rear end only, and if the coach is moving with the brakes set then they are either worn, out of adjustment, or both.


Like said earlier, air brakes set the parking brake by taking air out. The fact that the pressure in the tanks dropped doesn't play into this at all - you don't need air pressure to set the parking brakes in a modern coach, or to keep them set. You only need air to release them.

Got it, air leveling only.

Its rare for the parking brake to be that loose and not notice weak service brakes.

Start it up, put in drive with the parking brake on. It should not move under light to medium throttle.

If it does, you have bad auto slack adjusters or seized parts and need to have it fixed.

Just adjusting them isn't the way to go anymore. If the self adjusters don't work, it will happen again and quickly.
