Probe rear pads removal, try this it worked for me :
after removing the clip from the parking brake cable, loosen the parking brake cable adjusting nut, then remove the access bolt, and using an Allen-key wrench turn the calliper manual adjustment gear, anti/counter clockwise to retract the calliper piston, until it bottoms inside the calliper, then with the heel of your one hand, you can push the brake lever forward, and with the other hand pull the brake cable back, you can then remove the cable from its lever and bracket
good luck as I say it worked for me. Stuart J.
Ps replacing the calliper is even more fun .
