got the parts (2 kits) and on my way soon to dyno dave

There are no instructions  anything I should be on the lookout for?

I also have a bottle of unopened brake fluid, and 2 sets of front brakes just in case.

Is there a link anywhere to instructions  I printed out some generic ones from off the web on car calipers.

TIA

A few things:

1) DO NOT use petroleum-based solvents or cleaners to clean the calipers, especially while the seals and pistons are still in place! Use isopropyl alcohol instead.

2) A source of compressed air applied to the fluid inlet (where the lines attach) will help push the pistons out of their bores. Be careful, though - they can go flying.

3) Lube everything with clean brake fluid as you reassemble. Again, allow no petroleum-based products to come in contact with any of the brake system components.

thanks bagger I just got home from Dyno Dave who had a manual

dyno had some special brake part lubricant for the pin and outside surface of the piston we used after thoroughly cleaning the old parts with brake cleaner, a toothbrush and a soft wire dremel tool and then changing to new pads.

I am certain that I could do the job myself now as he let me do the right side after we did the left side.

The calipers were sticking cause they were all dirty and gummed up.  Big difference. The old pads were hardly warn but they are now in my bag as spares.  can never have enough parts on hand  :cooldude:

Never needed to do a rebuild after cleaning everything up. Perhaps fork oil had got in there or just it was dirty from riding in the rain and such. Whatever she handles and brakes way better than before and the front wheel is not locking up on me now
