result!!!! pistons all back in place...all pads out and interestingly 1 pad from each pair is worn right down while the other still looks like it has a bit of life left...is this normal to have uneven wear?? now the pads are out i can see their shape and the reference number (A01S) on the back...it looks like many of the Shimano calipers use the same pads on XT/XTR/LX etc. so i now know exactly what to look for...so pads ordered from discobrakes (despite the fact they never replied to my e-mail!!!) |
