Parking Brake Adjustment
 

First I've searched all the forums, read the DIY on Pelican's sight and referenced my manuals.

I'm trying to adjust my parking brake, as it only engages at the very last click at the top of the range of motion. For the life of me I cannot loosen the two nuts under the storage are in the cockpit. Is simple brute force required? I am afraid i am going to break the mechanism. Any tricks or wisdom based on experience?

I would suggest checking that you still have some brake pad left on the parking brakes, by removing the rear discs. If they are OK, then I would tighten the park brakes by turning the wheel adjusters as per the diagram on this site.

To answer your question, yes.
I takes a lot of force to get those two nuts separated.

Agreed, two wrenches in opposite directions, it is hard. Place them in such a way that you can squeeze them.together with the palm of your hand.
