Can anyone please give me advice to align my disc brake calipers.
I have just fitted new brake pads and am now struggling to align the calipers so that the rotor is in the centre of the pads. The rotor is now rubbing on the left side pad but there is plenty of space between the rotor and right side pad.
I have checked the pistons and these are both well back. I have also checked the rotor and this is straight. I tried sticking card in between the rotor and pads and holding the brake in while i tightened the caliper bolts but this did not help. Any ideas much appreciated?
