I've a 1997 Fireblade 900rrv - I decided to give the bike a service and saw that the front and rear pads could do with replacing. I ended up taking front and rear wheels off to give them a good overhaul, etc. With the brakes, the pad retaining pin plug is stuck on all calipers. It is the small flathead screw/bolt you have to remove before you get to the pin itself. Any ideas on how to remove the plug, please? I'm stripping the head if I continue in the same way. I've trawled the www but thought I'd ask here!:crying::idunno: I've tried a wd40 type lube but isn't helping!
