I've completed the brake refurbish, new seals, cleaned pistons, bled brakes.
Still seem poor though.
I was thinking that as possibly one piston per caliper was stuck, that the pads have worn unevenly, so that now that they are free to move, only a limited amount of pad is contacting the disc.
Or are they just weak brakes?

They're not great brakes.What you want is a nice set of FZR1000 calipers........ just so happens I've got some going spare...... good pads in em too. ;D

they are not as good as a beemer, the divvie 9 is a heavy bike, blue spot yamahas will fit, but the divie9 has fixed discs, whereas the blue spots are fitted to floating discs ;D

I just bought a set of blue spots with master cyl and pipes (probably need longer hoses).
I reasoned the 4 pot calipers are self aligning (within reason) and floating discs are less likely to warp than solid discs. But I wont be taking it on any track days so giving it a try.

A few people say they will fit. When done I'll post some pix.
I'm sure a D900 was advertised recently with blue spot brakes.
Nope... can't find the advert.

Hope so. Need to check the hose situation. Think the R6 stuff will be too short & D9 might have different fittings. Oh dear might be forced to fit some braided hoses. :-) |

Picked up the blue spot brakes today. Great ride to Hereford. Well managed breakers with helpful staff. The parts are lovely condition so I'm happy. As suspected the hoses are too short so after the exams I'll get some braided hoses and set to it.
The master cylinder will need a bit of jiggery pokery. The remote reservoir, which I presume on the R6 bolts to the top triple clamp, will need a bracket. Then simply(?) got to bleed the things.

Bugger, a front caliper is leaking.  I didn't get away with the "slight" pitting after all. Just ordered a new piston  |

There is a special yamaha grease for lubricating the pins and sliding unit in the caliper. If you can can I suggest taking the old caliper off, taking it to the shop and comparing it to a new one. Does it slide as well as the new one?
Considering the pitting in the piston it looks to me like you might need a whole new caliper. Eliminator, where do you live roughly? I could maybe ride round to give you a hand and let you use my Yammy grease?

Where do I live? The clue is under my avatar, adjacent to the word "Location" ;D ;D ;D ;D ;D The link at the bottom of this post gives details of how I went about this, so I am now a bit of an expert in stripping brakes ;D I use Castrol Red Rubber grease on any sliding pins in contact with rubber, use the same on the O'D of the pistons. The sliding pins are in very good condition, and the sliding action is good. The internals of the caliper were after I cleaned them, perfectly acceptable. Thanks for your offer though.
