Coffin-style master cylinders to fit an S4

mattb · January 31, 2009, 03:03:31 PM

Can anyone recommend a decent set of clutch/brake master cylinders that I could swap in on my S4?

Pics appreciated -- I'm getting sick of looking at those two fluid cups with the erector set pieces holding them up

thx

You could do the Brembo coffin masters/levers from Yoyodyne. You'd want the larger 16mm piston type for the brakes. Should be able to keep your current lines. About $100 per side with levers. Very economical.

Alternatively, with a much bigger budget you could do the Brembo 749/999 style with integrated reservoirs, or the Beringer billet coffin type masters. Both of those options probably will require new custom lines, but performance would be a step up.

Or you can trade with someone that has goldline calipers with coffin reservoirs. And, you could probably make a little extra $ out of it.

I'm sure if you ask, someone will bite.

I'd definitely consider swapping my 900SS coffin-styles for your S4 items, provided your brake master is the radial mount style.

999 masters have coffin-style reservoirs that a bit more shapely than the OEM Duc coffins. And they're radial. Edit: You might need new lines though.

OP asked for pics, so here's my 16mm coffin master ("900SS" type from yoyodyne) operating dual 4-pad calipers. It's also sporting a bleeder banjo fitting and CRG levers.

Not as purdy as Spidey's setup - damn that's a sweet ride

OP didn't state the year S4, but if the outlet of the current MC is oriented like this one (non-radial) new lines shouldn't be required.

Depends on what bars the OP is using.

OEM bar might be alright, I don't have an OEM bar in my possession, so I can't verify.
AFAIK my Cycle Cats would need a spacer to be able to run coffins.

Other clip-ons, dunno.
