Front brake

The front brake lever on my 2016 K1300S has never bitten so hard and early as that on my 2005 K1200S, but that bike had the electronic servo assistance of course.

Stationary, with the ignition switched off, I noticed today that just before the lever goes hard and the pads grip, there is the 'squishy' sound of fluid rushing from the master cylinder. Is this normal?

It definitely doesn't happen on my girlfriend's Honda CB650 . . .

Brakes work fine, by the way, and bike will be get a major service at the end of summer, including pads and fresh hydraulic fluids.

Thanks, David Mc.

Re: Front brake

Just tried mine. I heard a faint hiss that sounds like it is coming from below the steering bridge. I am guessing it is the sound of the fluid at the fitting where the line splits to feed the caliper on each side. If you let off and reapply the brake fast enough there is no sound so, again, I am guessing this is because the front calipers pistons have not had time to fully retract so there is less fluid movement. Good luck.
