These brakes are weird to my eye. Four piston brembo calipers on each side that are rigidly, axially mounted
But the discs are rigidly mounted to the wheel too -- just bolted right on to the hub This confuses me -- I've never seen anything like this before. I've had a Ducati with a radial-mount brembo caliper but the disc floated on bobbins so it could compensate for slight misalignments between the disc and calipers.
How does the braking system on the F800 account for misalignments? Surely if one set of pistons in the caliper is slightly dragging and doesn't push out as far as the opposing set, you're going to have issues with the brakes?
The reason I ask is that my new-to-me F800GT has pulsating front brakes....the first thing I wanted to do was clean and lube the caliper slider pins, only to find out there are none. Then I wanted to clean and lube the bobbins -- only to find there are none! The pulsating has improved a bit after using the brakes really hard a few times, but it seems worse when the bike is cold. Other suggestions? Bike has 24K miles on it and the pads look newish, but I think they are the original discs.
