Coffin reservoirs although not necessarily hideous are made of a metal that seems like its designed to look like shite after about 3 months (& thats being generous). I've gotten after market lids and that helps but the rest of the coffin is still this hideous dull gray. Anyone PC these puppies. (got pics?) Seems like it shouldnt be too hard any caveats? Changing them out for aftermarket requires changing out the entire master cylinder and I'm a bit sketchy on whats required for that.

take them off, open them, cover the reservoir and paint them . .. you can do it . . . it's easy

Or replace them with same bore size Brembo remote reservoir style.

They're available in large pivot style, so you can swap over swanky levers, if you've got them.

Or in small pivot, if you want those.

Clutch side is 12mm or 13mm diameter piston.

Brake is 13mm for single disc, 16mm for dual disc.

If you examine your masters with a magnifying glass, you can find the number stamped on them.
It'll be something like 1K12-13.
That would be a 13mm master.
The numbers are quite small, faintly stamped, and usually on a surface that's quite hard to see when mounted on the bike.
IIRC, coffins usually have them on the forward bottom of the 'reservoir'.

Would def go this route before shelling out the coin for PC. Yoyodyne is the best place for the entry level "Goldline" Brembo's. Or if you have a Motowheels "VIP" membership they are quite affordable as well, $120 each IIRC. It would be a performance improvement while you were at it, as the coffins were designed for single disc setups and Ducati used them on DD bikes to cut costs. They really don't push the proper amount of fluid for DD.

Tell him Eli sent you :P

Goldlines are the way forward.
Coffins look really old fashioned to me.
If you have a single disc then fitting a dual disc master cylinder is a really good upgrade.

Caramba!

There's both Coffins and Goldlines properly sized for single or dual disc applications.

Single disc 13mm, dual disc 15mm or 16mm depending on what you like.

-----------------------

I've tried a single disc setup with 16mm master.
Lever effort was quite high.
If you like the front brake to have the lever effort to braking ratio of a late 70's / early 80' bike, go for it.

Then you would go 13mm for twin disc, but twin sliding 2 pot calipers? Am I correct in thinking number (and size) of brake pistons in relation to Master Cylinder?

they use a 15mm master.  there's only 2 of 28mm pistons, but they have to travel twice as far comparatively.

Thanks. I actually needed that clarification for a special job. I'll pm you. Sliding pin caliper travel explains it then. Thats good news.
