I recently noticed some vibration when braking at low speed. It is confined to the front brake but I cannot reproduce it on every occasion, it seems to come and go.
Any ideas before I take it to the dealer. It is still under warranty.

Are you inadvertently actuating your abs?

Hi Bravo. I don't think so. It's not the pulsing sensation that you get with the ABS. It seems to occur when I move off after parking up. I left it for an hour near Ludlow Castle last week then rode off down hill quite slowly waiting for some friends to catch up, as I braked for a junction I noticed it. It then happened at the next junction (similar circumstances).
I didn't notice it again on the rest of the ride.

Could be the pump pressurising the system?

Most peculiar.

I'm a bit concerrned it may be a warped disc so off to the dealer I think.

Just a thought: Could it have anything to do with the fact that the bikes have the so-called "floating disc brakes". Whenever I touch the front brake, I feel it's sometimes bracing itself.

How many miles on the bike? Are the pads originals or replacements?

Front brake lever also actuates the rear brake.

Some brake pads can leave a deposit on the rotors which will feel like warped rotors. The hotter the pads get the worse the potential problem. Especially if you stop when the pads are really hot. The pads cool and little chunks of brake material set solid on the rotor. There was one make of softish type pad that was especially prone to this but I can't remember which, hence my question if you are using OE pads.

Wait for the brakes to cool after a ride and run your finger over the rotor (disk) to see if it feels gritty or lumpy.

The bike has 6K on it and is still on original pads. I'll have a look at the discs next time to see if there's any residue on them. Had a run on it yesterday with no signs.

I discovered the same on my bike. It ended up with 3 weeks in the dealers shop. They took it wery serious. I got new Dish, Caliper, hose, handle and ABS and after a couple of months i discovere the same error again. This time they changed Dish, pads and bleeded in a special way. First time i noticed something was when braking and the fod brake trembled, i could alos see that the black painting on the edge of the dish was melted away.
All was changed under Warranty.
