I know this was a left at one time because the bleeder is on the bottom, but are they reversible or is the sliding bracket different? It seems to have a curve or bend to it. You can see an "H" on this one. The left side didn't have a marking. The caliper tilts inward a few degrees. (the inner pad touches at the bottom).
