While moving hay yesterday the plastic bushing on the right side lap bar came off and allowed the parking brake to try and engage while I was moving full speed. I used a vice grip to disengage the brake and keep it there.But now when I make any type of right hand turn sounds like something is binding and you can feel a clicking on the floor board on the right hand side. I'm guessing I will need to do some type of repair on the parking brake??? But I have no Idea what needs to be taken apart to get at this area any help is greatly appreciated. I also am wondering how to access the chain case to check the oil levels this is a 1993 1840 I have the operators manual that shows the small inspection covers inside the cab but do not see them in mine do I need to remove the rops to check them?? also between the wheels on each side is a round cover about 8 inches with six bolts can I remove these to inspect chain cases??? looking at an exploded view of this cover in the parts manual appears to be a lot of parts behind this cover and I do not want to have parts come out that I have no Idea how to put back in any idea if by removing this cover to check the chain cases I'm making a lot of extra work and $$$$ for myself. Thanks Mike
