Hi. I have been going at it trying to get the tear callipers off for over an hour. Not the cage, just the caliper that goes over the pads. I have managed to get the top bolt lose on the passenger side and the bottom bolt lose on the driver side. I tried to move the caliper round and out the way to get the pads out but had no luck so I need to get the other two bolts out (one each side). Am I missing a trick? Do they turn the other way for some reason? The only luck I have had so far is with a17mm spanner and a hammer to loosen the bolts and then get a 13mm spanner to use with the 17mm spanner to get the bolt out. I am sure if you have done this, you will be able to get what I mean.
