How to on brakes

Anyone have a full "how to" on brakes for a 77kz900? bike has been sitting for like ten years and brakes are sticking in back and front is barely working

I would look for an origional Kaw service manual on eBay or someplace.

Or...

Remove the calipers and drain everything.

Dissasemble the calipers. To get the pistons out of the calipers, you place them in a doubled plastic/or fabric bag, and apply some compressed air to the brake line hole.
Carefully, and slowly till the piston pops out.

Then you just clean up the caliper bore and piston lightly with some scotchbrite pad.
Use a brake rebuild kit, and reinstall everything with clean brake fluid.

bench test your assemblies with compressed air before installing. The piston should slide out slowly with just low pressure, and slide back in by hand.

GL!

If they are so bad that they are sticking, I'd add to TeK9iNe's advice to rebuild the master cylinder and flush the lines of any crud and moisture. How do the flexible lines look? If heavily cracked, I'd consider new ones. Brakes should not be done half-a...sed.

BIG +1 on the factory shop manual. It's worth its weight in scotch.

If the lines are original or old, maybe look into replacing them. It's fairly common for folks to get stainless steel braided lines - the kind w the outer protective plastic sheathing will protect your bike from scratches. I installed Goodridge lines & fittings. If you've changed the handlebars or the upper line is otherwise too long, now would be the time to get the correct size.

Z1E carries a large variety of brake hoses, different types, sizes, etc.

Good Luck!

Thanks guys, i picked up a manual and going to tinker this weekend. Im dying to get the bike on the road. It screams but feel like a stupid twelve year old on his first crash and burn when trying to stop. (i was a little to impatient to feel the power)
