Rear brakes... what I did wrong and where to go now?

[Inhouse Bob]

Bob i'm not the best to explain here, although i always get the job done i find if a bit fiddly to do so.
There are two sliding bushings that should have enough ( silicone preferably but anything will work here ) grease under the dust seals to enable the caliper housing to freely slide and find the best position on the rear brake disk ( yellow dot ).

Before you begin check that the caliper feels slightly loose to move with all bolts tight.



They normally wear about the same on both brake pads unless they are prevented to slide sideways and adjust freely.
The rear ( sliding ) bolt ( 12mm socket ) has to be loosened to lift the caliper enough to replace the pads.
Also make sure the slot in the caliper frame which pivots around the axle is located correctly over the square piece on the swingarm which stops the caliper rotating in either direction with the rear brake applied.

The ( 8mm socket ) pin can then be unscrewed and the pads replaced, this is the fiddly bit to get the new pads to seat both resting on their supports against the spring tension before replacing the pin and the bolt.

It is possible to install the pads not resting on their intended supports and yet looking ok, that may have happened in your case, have a look if they have worn correctly.

Likely more advice is coming your way but that's my bit of advice for you.

Hi again,
Thanks MAX. I finally dove into this after waiting a good while for parts delivery. You got me 85% there.
I am having much trouble, mostly because I don't have three hands and a prehensile tail.
Three things...
1) I bought a new pin because the old one is a bit worn looking and it only cost $4.95. But the new one (it is Honda brand) doesn't have the little white O ring near the end like the old one does. That ring doesn't look to be removable from the old pin. I looked on line and the old pin stock number has been replaced by a new one so maybe they decided the little O ring isn't required??
2) I also bought a new caliper pin(it was cheap, too) but I can't see any way to remove the old one. The original still seems to move freely so I guess I will leave that alone. Thoughts on that plan?
3) How on Earth do these pads connect to the caliper body? I just can't get anything to "hook" under there. Maybe this is where a third hand would come in handy? I feel like I get one in some sort of proper place but can't get both. When I feel like I have it, the pads both fall loose again, so I don't think I'm getting it. I certainly am not confident in what it is doing so far.
I have the manual but it is very vague as to how this all works. "Put the pads in, bolt it down." Not a big help
Grrrrr. Any help would be awesome.
Thanks!
