Nah, it gets a bit out then fluid just pumps around the outside. Have taken the caliper apart and will see what staring at it does.

Stink. Dug it out...

All from bleeding it, then putting the wheel in without the pads accidentally, pumping the lever waiting for bite, see fluid pour out, try to push piston back in but it must have popped out at an angle.

Got a new caliper on the way from CRC

I converted my triple 9 spd slx to a double (11-34 cluster - 22 and 36 on the front. rd 772 shadow with sgs cage.)
I get a lot of rub in the FD which really makes a lot of the gears useless. I presume i need to change it??
I also presume i would be better with a 36 on the back? with a 22 up fromt i dont really have any trouble climbing but was also wondering about a bigger granny
thanks

also wondering (shifting bits from bike to bike) - with my current set up - could i put a 10 speed shadow plus RD in place of the 9 speed RD presently on (9 speeed xt shifters and a 9 speed 11-34 cassette)?
thanks

note : would change cluster and shifters later

Nope, 10 speed and 9 speed have different pull ratios.

Where is the chain rubbing?
I managed to get mine rub free when I dropped the big ring.
Only go 36 is you really need it.
I only run 11-32 cassettes and I winch myself up ok.

thanks for that -as i thought about 9/10 interchangebility - i run an old 8spd XT with a 9 speed setup on an older bike and developed a distorted view of what works with what

wrt to the FD, any crossing ie bigfr>bigrear or smallfrnt >>small rear causes rub- means i can use the top 2/3 of the cassette with one ring and the bottom 2/3 with the other - FD is an slx m660

This is my exact setup (bar the derailleur models) and only get rub when fully crossed small/small, 36f/34r = no rub, old Deore 3psd front mech, old X9 rear, all good.
Maybe a bit more faffing with front mech setup? Perhaps lowering it a little now that it doesn't have to clear a 44t?

Going to a 12-36 cassette (or 11-36 if converting to 10spd) sounds like a good excuse to go single-ring, climbing in 22/36 could winch you up a wall.

I find that lowering the front derailleur causes issues, I think it should still remain in the same place after removing the big ring so the wide section at the bottom of the cage is in line with the small ring.

The dual ring specific mechs are 11ty billion time better for this eg http://www.chainreactioncycles.com/us/e ... -prod27692 they have a better cage shape.

I ran one with 11-34/11-32 + 22-36 for yonks

do they work with the ghetto (triple, throw away big ring, add bash) doble set up though - is the spacing the same?

Yes, but they can have trouble clearing the bash in some setups.

Yes they do, as that is exactly what old (9 speed) dual ring used to be.

What setups? I used e13 turbochargers/superchargers and the factory slx bashrings with never any issues.

From The Hive "For guides using a bashring in place of the big ring, a triple front derailleur should be used."

Only mentioned as I've never used a double front derailleur and came across this recently.
