Operators manual and service CD have no mention of adjustments that can be made other than pedal neutral so traction pedals don't bind on application .
One of my operators mentioned that his machine wouldn't hold with the park brake anymore .
I check the linings and they seemed to have plenty of wear left in them .Checking in the parts book the brakes are only available as an assembly ? Asking the dealer about this they said there is a brake service kit available for $150 dollars CHEAPER ? Guys on the tech site showed the assembly to be 233.XX$ US . So for 143.00 $ Canadian (kit) a side you can rebuild your park brake . Another example of absurd pricing . (This is not a JD thing all colors do it ) so when ordering parts always ask how much no matter what it is . To me this pricing is way out of line and the brake pads should be available.
After taking a closer look at the brake I could see were an adjustment could be made .
In this area I'm pointing to there are washers and shims for the actuator . Maybe the shims are available because there is a break down of individual parts for purchase .
Taking a few shims out and replacing it with a washer
few picks of parts . keep track of how they go back together
First attempt I didn't take shims out and it was snug on disc . Taking 2 a side out did the trick .
As good as new holds well on slops now .
Sometimes in this field you have to figure it out yourself . When the park brake pads are worn down to far i'll be resurfacing them myself if the hardware looks good .
