Remove calipers on kawasaki versys kle650

If the lever has to be pumped then there is air in the system, use a brake bleeding kit that forces fluid in or draws it outOr try pushing the caliper pistons right back in, holding them there & bleeding
Alternatively remove calipers & tap in different positions

Just follow this instructions:

1 Unbolt the brake caliper from the front fork or rear swingarm, using a socket wrench. Use a 14-mm hex socket to unscrew the front caliper bolts, and a 6-mm Allen socket for the rear caliper.
2 Slide the caliper off the brake rotor. Suspend the caliper from the handlebars or frame, if needed, using a bungee cord.
3 Pull the hair clip pin out of the brake pad's retaining pin on the outside face of the caliper using a pair of needle-nose pliers. Push the retaining pin out of the back of the caliper with your finger.
4 Pull the brake pads and their spring clip out of the caliper. Retain the spring clip, and discard the brake pads.
5 Reinstall the brake calipers, following the reverse method of removal.

I hope this will help you. thanks

HI, THE TROUBLE WITH BRAKES ON THE OLDER BIKES IS COMMON, AND NOT UNUSUAL FOR THIS TO HAPPEN ON A YEARLY BASIS, MY THOUGHTS ON THIS ARE THE BRAKE CLEANER WILL ONLY REMOVE LOOSE BRAKE DUST ETC, THE TYPE OF STICKING YOU ARE GETTING IS BEST CURED BY REMOVING THE CALIPERS FROM THE FORKS AND CHECKING FOR FREE MOVEMENT OF ALL PARTS, SLIDERS, PISTIONS, PADS, ETC IT MAY BE THIS TIME YOU WILL ONLY HAVE TO SERVICE 1 CALIPER,NO NEED TO REMOVE BRAKE LINES OR DISTURB THE PRESSURISED SYSTEM. WITH 1 CALIPER REMOVED GENTLY PULL IN THE BRAKE LEVER AND CHECK OPERATION OF PISTONS, DO NOT PUSH OUT ALL THE WAY AS THIS WILL CAUSE THE FLUID TO LEAK OUT OF THE SYSTEM, PUSH THE PISTONS BACK HOME GENTLY WITH SOME GRIPS TAKING CARE NOT TO DAMAGE PAINTWORK ON CALIPER OUTER, A SLIGHT RESISTANCE SHOULD BE FELT, IF YOU HAVE TO USE EXTREME FORCE THEN THE CALIPER WILL NEED A COMPLETE SERVICE, PEPEAT OPERATION ON OTHER CALIPER, PAUL

You can take the cover off, nothing should fall out.

Some guys leave the brake disk on, some remove the four bolts and leave the disc in the caliper.
Just unbolt the wheel and remove the axle. A “very helpful” rating for this answer? Thanks!

you need to bleed the brakes real good you have air in the line or caliper this happens when you disassemble the caliper hope this helps give us a rate
