Do you have inboard disc?

If yes do you have pull off springs on the park brake calipers?
The springs that are on the calipers are not strong enough and will let the pads stay contacted to the disc and wear down.So you have to keep adjusting them.

I have a limited pull on my replica jag brake handle so I made a longer lever that attach's to the handle. Giving it a longer throw.
