John Deere Park Brake adjustment

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 .


 Update:

Well I managed to get one more season out of one of the 2 units . Now it's time to replace them .
The brake pads are still not available .You have to buy the caliper assembly for $400 + a side ?!! or when your jaw drops to the ground you may get offered a caliper rebuild kit for ONLY $200 + a SIDE.
Ran it by the student that drops in every Wednesday at a guess . He figured $150.00 for both .

All Ridiculous Quotes .


Not understanding why you can't buy the wearable item . Hardware still all good even the slides have little wear . Springs still work great . I don't get it . 


A bunch of pics at different angles for reassembly.


Pretty much dead center are shims .




Found a local guy that sold friction material . Picked up enough to do both machines and maybe some TX gators for a whooping $10.00


Trying 2 adhesives people have tried on-line  


JB weld set up solid and marine epoxy may take a little longer to set up .
Took a little while to make adjustments with washers and after extending park brake rod it worked out great .
$4.00 Canadian is a far cry from $800.00 plus taxes or $400.00 + tax minimum.
These kinds of pricing could very much determine future purchases if you don't have A good EM.
We do love are 2500 E great greens mowing units .
