Thai has happened twice now and I need some advice. I am parked an extended time and I go to move and when put in drive and brake released the coach won't move. I give it some more throttle and with a loud bang something feels as if it breaks loose and I can move the coach.
I assume this may be something sticking or hanging up with the brakes.
Is there any thing I can look at,grease,spray,hit with a hammer,etc.
Is this something to be worried about and have checked soon at some overpriced repair facility or can it wait till I can find a skinny friend to crawl under my coach?
