Ok so I'm in the process off getting a new left side rear caliper but the other still works since rich unseized it.

I have found the handbrake cable guide that shows the reset part of the handbrake but it doesn't show how to get to it...

Is there any bother way to stiffen the handbrake? As it roles back on hills unless you pull it right to the top..

Also can you replace the plastic handbrake cover?
