Semi-Floating Brake Disc Buttons

[ozsn]

How much and how easy should the stock Brembo semi-floating front brake buttons on a Monster 620 move? What is the best way to loosen them up and clean them out?

Hit them with a hammer and a socket.

The inside, outside, or does it matter?

You can use a screwdriver or allen wrench to lever the buttons around.  If you are VERY careful - wiping off all the excess stuff - a small amount of some light oil like wd-40 will keep them from corroding and freezing up again for a while.

Thanks, I am starting to think the guy I bought the bike from did motocross with it. There is dirt and gunk in everything. I had to take the throttle assembly apart because the dirt stuck between the plastic twist grip and the handle bar was so bad you could barely twist the throttle. Oh well, I guess the thing to learn from this is ride your bike often. The person I bought it from only put 1000 miles on it over 5 years.

+1 Sounds like he wrecked it and let it sit for a long time while he repaired it.

I used the 3/4 socket and hammer method  onmy S4 discs they rattle now and work perfectly. My M750 has Galfer wavy discs and the SS750 has Brembos which i will do the Hammer and socket job on when they get too grabby or warped.

You have to take them off. and i'm a stickler for symmetry so from both sides. Oh and don't go too far!

Hitting the outside doesn't loosen anything. You're trying to flatten the spring washer on the back.

The important thing is to support both the carrier and the blade when hitting things. Otherwise you could bend one or the other.
