- Use the correct size socket and rachet to remove the caliper
think it is a 7mm alan key, the one that never ever seems to come in a set. Got one to fit my socket set for a couple of quid from europarts.
Make sure you have one before you start.
If you are local can lend u mine
Had another look this morning -
deffo a 7mm alan. (Not 17 if you read this earlier) sorry
