I don't think there is an online manual available
There's a plug, screwed in over the pad pin.
Remove that and loosen the mounting pin
Remove the 2 caliper mounting bolts
Remove the pad mounting pin and the pads
Clean the pistons and push them back into the caliper
Fit the new pads and hold them in place with the pad pin (I put a bit of copper grease on this)
Refit the caliper ( 26Nm)
Tighten the pad pin (18Nm tho I always do this by hand)
Replace the pin plug
Pump the brake lever & check the fluid level.
As the others have said, the Suzuki manual's well worth the money.
