Guyz ,Looking for some dimensions if anyone has a z thou a1 or a2 caliper in bits,need piston dimensions diameter and length,gap between piston bores when pistons fully back,.....got a rotor here 7mm,new pads are 9mm apiece,disc rotor is dead central,thinking may have mismatch of bits,reckon would need to lose 3mm at the mo so brakes wouldnt bind..Ta Paul J

Thats Great Adrian,explains why my set up is binding,my rotor is 7mm,new pads are supplied as 9mm or 8mm a piece plus 1mm for the anti rattle shims,that makes 7+8+8+1=24 at the best some pads are 7+9+9+1=26,both way over 22.6 as you state,whats the thickness of your rotor? are your pads thinner than 8mm?..Many Thanks Paul J

The disc is 7mm will check the pads pretty sure I couldn’t use the anti rattle shims and had to file down the pads to get them to fit.
Will check pad thickness tomorrow.
