Model B

 

GMA "B" caliper and pads.

 

I see the B pads available on various websites. Still a little unsure about installation. I've done plenty of brakes and other repairs on cars but not much on bikes. I see the outermost bolt should be loosened first then the two that hold the caliper to the bracket can come out. After that I don't know what to expect. Looks like the pads have roll pins holding them in. Not sure what I will find, trying to avoid a pile of parts falling all over the ground when I pull the caliper off.

 

Thanks for all who contributed to this effort. Swapped out the pads yesterday without incident. Lots of brake dust was cleaned out before installing the new pads. Still have the squeak coming from the front brakes but that will have to wait until I get new tires. At that time I'll go for a new disc. Thanks again for all the help.
