So I'm changing the front brake pads on my 06 T100 at 6400 miles. The two bolts that hold the braking mechanism on are fine and come off easily. The screw that holds the brake pads in place came out easily, but only half of it because it's broken clean in half in the middle. I'm under warranty so that's helpful, but I'm somewhat dissapointed. Has anyone else seen this happen?

Not yet, but I'm due some pads soon :???:

If you are talking about the pad retaining pins, two long, thin bolts with threaded allen heads and threads at the ends, they can be tricky to remove. I just installed an EBC ProLite rotor and HH pads and noted either in Haynes or the Service Manual that the pins were to be very lightly lubed with "copper" lube, which I took to mean anti-seize. The fact that they would call for anti-seize suggests that they seize. My pins came out okay after almost two years. Loosen the pad retaining pins before you remove the caliper from the fork. I also checked the rear brake, and since I hadn't had it apart for two years, I decided to remove the caliper and pads and clean the caliper. I noticed the rear pad retaining pins were pitted. I cleaned them up with 000 steel wool, but will order new ones, since the pads are supposed to slide on these. Glad you're under warranty, but still a pain.

The pad retaining pins you referred to are only present on my rear brake mechanism. On the front brake, a single treaded pin-screw holds the pads in place. If there is anything else, I wasn't able to see it since I couldn't take the thing apart with the broken screw.

The good news is, the brakes performed the same with the broken screw as they did before the screw was broken (presuming it was at one point unbroken).

The bad news is, I have a new found fear of brake failure.

Yes, you are correct that the back has two pad retaining pins, while the front has one. The front pin is under a short screwed-in plug. This plug has a slotted head. The long pad retaining pin is under that. It has an allen head. In the rear, there are two of these long pins, and they are not covered by any plugs. Is it possible that you removed the covering plug (about 1 cm) and not the pad retaining pin under it? If the actual pin holding the brake pads in place is broken, I would have the dealer pick the bike up rather than riding it. I worry that brake failure in this case could be a front end lock up. The brake pads slide on this pin; an inability to do so could be a serious problem.

Holy cow! I bet you're right! I probably just removed the plug and couldn't see the pin was separate. The underside of the plug looked rough and I thought it was broken!

Thanks!

Copper lube is NOT the same as anti-sieze.

It is a specific high-temp lube that withstands the temps generated while braking while lubing the pad guide pin(s) so that the pads can freely retract.

Well then, where might one find COPPER lube? and how might it be labelled? Anti-seize has copper in it, and the Haynes (British) manual said to put some "copper lube" on the threads of the pin allen head as well as the pin shaft, so it sure sounded like anti-seize. Good thing I just put on a very light film. I have seen products designed to be put on the back of the pads (where they also suggested some "copper lube" but I opted out on that), but that is usually if one has brake squeal, which I've not experienced on front or rear of the Bonnie.

I just put a smear of white grease on the pins and pad backs, just don't get any on the disc surface.

Anti-seize is a lubricant. They're probably suggesting this :

Coppy anti-seize
