Cedar Garage pergola attachment options

Hi All,
I’m currently building a cedar pergola to hang over my garage doors and am trying to find the best way to anchor to the wall with potentially cracking or pulling out anything. Its a brick veneer wall with an air gap and then hollow cinder block.
There will be 3 brackets holding up 4 2×8 cedar boards and 2×2 pieces on top (picture is a very similar set up to the one I have built but spanning 2 single doors).
Is using a couple 3/8th inch sleeve anchors in each bracket attached to the brick veneer enough? I can attach the back 2×8 running across to the wall similar to the picture to remove some weight which could go all the way through to the rim joist above the garage doors.
Appreciate any help!

I would run threaded rod through the block (and interior framing if any), fender washer and nut inside, washer, lock washer and nut countersunk in the bracket.
Bottom of bracket I guess I’d use a sleeve anchor. If it’s decent brickwork your wide bracket should distribute the load enough to not crack the mortar.
Your idea on the back board I’d agree with. Pull out on that should be less than the bracket. I might use a spacer between between it and the brick. Might have to blow it out once in a while.
Post up a finished picture when you’re done!
And don’t grow Wisteria (or whatever that tenacious vine is) up and on it.
Appreciate the response, does threaded rod thickness matter much in this scenario as I don't think much sheer strength would be necessary. Could maybe add an adhesive when inserting the rod through.
I do like the idea of using spacers on the back 2x8 piece.
I'm curious why you mention not having a vine growing up onto the pergola? Due to the potential of damaging the brickwork?
I’d use 1/2” rod as I have a long bit in that size for my rotary hammer drill.
I have seen what I think I remember was wisteria that grew up a pergola attached to a house actually pull it askew on its way up to the gutters. Check with someone with more plant acumen than I have memory. The vine in question was old, didn’t just grow up in a couple years and do the damage.
