Purchased a 2003--- 3500 Dutchmen Express motor home Drove 7000 miles and when returning home on a hill i touched the brakes and had a bad wobble on the front passenger side which only lasted a few minutes never happened again until a another 5000 miles and it was only for a few minutes some people say it is a stuck calibre or a flex hose, any one out there having the same problem or know of someone that this has happened to. Thank you Art

 

Sounds like the DEATH WOBBLE
This video shows an exstreem case but they are basicly the same.
When conditions are just right, it will break loose into a wobble.

Lift it in the air, with another set of eyes (help) start looking for worn tie rod links, stabilizer bushings then even a wheel alignment

 

thank you for your reply,what i forgot to say the wobble only happens iswhen i touched the brake peddle and stopped when i removed my foot from the brake peddle

 

Sounds like you either have a cracked brake rotor or a warped brake rotor

 

thanks glen,

 

My thoughts exactly!

Have the rotor(s) resurfaced or replaced and you should be good!
