..... you don't even have to remove the whole calliper, just the two smaller bolts that retain the hydraulic plunger.

Be careful to replace the anti-squeal shims and the stainless steel carriers at the front and rear of the pads.

I've found that the pads are a little too long and will not slide parallel with the carriers. It is necessary to grind off a little metal from the tabs on the pad backing to get them to slide parallel. (There have been comments on here about finding brake pads worn to a wedge shape because this hasn't been done)

Finally, make sure that the steel bushes through which the smaller bolts that retain the hydraulic ram slide easily in their plastic carrier. Push out the steel bush and remove its plastic carrier (by gently scrunching the carrier up and pushing it out of the housing). It may be found that the inner of the housing has gone rusty and caused the bush to be very tight in the housing. Before reassembly, clean the rust out and put a thin smear of grease or Waxoyl inside the housing to deter future rusting.

In this way the hydraulic part of the calliper will remain 'fully floating' and promote both pads to wear equally. I've found that it helps even out brake imbalance which is a cause of MOT failure.

Use a bit of noodle and this job should present no problems.
