My brake pads have worn to the point where the lever can no longer apply full pressure, and there isn't much pad protruding beyond the pad mounting. So they need replacing and I want to do it myself rather than handing over to a workshop and losing the use of the bike for a day or two.
I think (from appearance) my rim brakes are HS33. Although my bike is newer the details match those seen in this company video on changing the pads:
The side with the quick release mechanism does indeed undock easily and can be quickly changed. However the other side (where the hydraulic lines arrive from the brake lever) lacks any quick release and I think he says at 0:44 to dismount the wheel to change the pad on the other side!? Is there really no easier way to get that pad changed? Would you ever want to change just one pad anyway, if not what does the quick release achieve if the next step is dropping the wheel out?
