(A similar sleeve is found on the earlier VF calipers) While refurbishing the brake calipers on Project 14 I came across an all-to-common issue — the lower mounting point on the rear caliper.
The mount consists of this "sleeve," as Honda calls it, which is required to slide slightly to & fro in its boss as the brake is cycled. Trouble is, this particular pin is usually severely corroded and often frozen in place. The brake will still function but at a fraction of its potential. It seems well-protected by two tightly-fitted rubber boots (shown in background) but still suffers from its location at the bottom of the caliper.

This is the result of the sleeve being frozen in place. The inboard brake pad isn't allowed to slide freely, resulting in only the upper portion making contact with the disc. Note the bevelled profile of the pad. These pads are junk.
Fortunately, the sleeve and boots are still available from Honda. The sleeves retail for $10.85 and the boots for $3.85.
The hard part is freeing the sleeve from the caliper — this one was soaked overnight in parts penetrator and twisted loose. The boots are often in reuseable condition.

The bore itself typically only needs cleaning with a brass brush and flushing with brake cleaner. I then coat the bore with some brake caliper grease and reinstall the sleeve and seals — there's a trick to this; install one seal, push the sleeve all the way through from the opposite side, install the second seal then slide the sleeve back to engage the second seal.
I'm sure if these sleeves were serviced at each brake pad replacement or say, ten years, they'd remain in useable condition.
Good to go! Let's mount 'em up.
