Hi Guys. Recently our Rx400 reached 1000 hours and this year they are wanting in-house maintenance on all machines. Our mechanics aren't really experienced with Roadtec equipment especially something like a mill. They've ran into a few issues and I just wanna get some real info on our problems. We've had issues with our parking brake, its basically obsolete. What is the procedure for adjusting the brakes or does this call for some kind of replace/rebuild of the system? Ill ask my other questions later. Would love the help. Thanks.
