So I bought a new SLX brake from CRC, and some spare pads. After a weekend in Wales its now time to replace those pads, but the ones I bought are a different shape – the new pads have the hole in the middle, not on one end, whereas on CRC and DiscoBrake all the pads offered have the hole at the end.

Anyone have any idea which will fit?!

From superstar… You want the S5 pads…..(Old XT/SLX is S1)

Do you want my spare pin?

And if your brakes are M666 or M675 and you want the pucker Shimano offering:-

Resin unfinned – G01A
Resin finned – F01A
Sintered unfinned – G03T
Sintered finned – F03C

You want the S5 pads

The way I read the OP he needs the S1 pads!

OP – do you know what the brake part number is? M665 or M666, or even a link to the actual brake you bought?

Yep, bought the M666: http://www.chainreactioncycles.com/Models.aspx?ModelID=67247

The S5 shape is the one I need on the that chart above, cheers Doc.
