I have to ask why your looking for replacements. They usually don't bugger up. There is a trick tho because of the Hand brake mec the pistons have to be wound back in when replacing pads . Sounds simple but catches folks out all the time. so if your looking for replacements because the pistons wont push back try turning them. Ive seen a lot destroyed by dudes trying to hammer them back in.
Hammer the only tool a good mechanic needs.
