Thank you cn90! You are so wonderful!

I wish I had this parking brake DIY two years ago when I gave up on replacing my parking brake shoes for lack of a DIY! The Bentleys were useless for me for the parking brake - and there wasn't a DIY that I could find - so I left them alone.

Nowhere does it even say which direction of the star wheel does what (you did! Thanks). It's not obvious which direction does what until you've moved the star adjuster wheel a LOT of clicks and by then, you might hopelessly have misadjusted them (ask me how I know); so, precise details like those you put in your DIY are fantastic timesavers!

Your DIY above will help everyone!

One question I have left over from a rear wheel brake replacement was the thickness measurement wear limit for the parking brake shoes.

I realize your brakes weren't holding so you knew to replace them; but for me, I was wondering if mine were getting close to the wear limit. But I couldn't find the wear limit anywhere (surprisingly).

Does anyone have a figure for the parking brake shoes wear limit?
