E-brake carrier

[Floats]

Hi Gents,
Please help, my RH E-brake has inadvertantly engaged, by itself, a few times.
I managed to find and fit a reasonably good carrier but the contact points between the shoe and the carrier needs refacing and I need some help under standing the correct angles required.
Take a look at the photo and sketch attached and please advise me of the recommended angles required depicted by the red arrows.
Regards
Chris

Thanks Tom,
Much appreciated, I thought as much and trimmed the contact surfaces nice and square as in your photo.
Regards
Chris
