Brakes are sticking on my KZ750e

This is to assure the pads are not dragging against the disc while the brakes are not being applied. If dragging (akin to continuous light application of brakes while riding), excessive heat build-up may cause the brake to progressively bind more and more until it locks up.
Could wait until it completely cools off, then adjust (widen) the gap. If brake again heats up and begins toward locking, check the mentioned gap and may find it no longer exists, which means the gap was set too small, and should be adjusted even wider.
Would also change the fluid. Suck out most -- but not all -- old fluid from m/c reservoir. Fill with new fresh brake fluid. Bleed normally until most -- but not all -- reservoir fluid is pumped through system and out the bleeder hole. Again refill the reservoir.
Good Luck!

use a small cold chisel and strike it an angle the head of the screw that is option 2 is to drill thru the head of the bolt with one size bigger drill bit and then remove the left over peices with vise grips.
Good advise...Think I will go for option 2 since I have pretty much destroyed the head anyway. Maybe I can get a hex bolt that will fit to replace it...
Ok...was fiddling with the calipers again and came to the conclusion that one IS locked up. The other may be well on it's way to doing what the other is soon. What are my options here? Rebuild? Or is it gone and I need to replace now? Want to get the brakes working soon so I can enjoy my new ride!

When the brake lever is pulled, fluid runs through causing the pads to compress on the rotor. When I let go of the lever, the space between the pads should open back up on its own and fluid should return to the mc. Am I correct or will the turning rotors sort of push the pads away? I'm asking because the caliper that is not locked, will move back to the correct position, but only with some help from a screwdriver used as a pry-rod...
Just want to know if that one needs repair/replacement too!

I have also stripped the screws on the MC cover. I went to the Home Depot, got me a stripped head extraction Kit,(in the bit section) and with a a drill in reverse, extracted the screw with no drama, following the instructions. There is no need to tighten these screws too much. I made that mistake once.
The word 'rebuild' on the calipers is a bit exagerated. Mainly is cleaning (tedious), and replacing seals. By your description, I don't think you have much of a choice. Like I said before, is not difficult, nor expensive, partwise. It is getting rid of the air later that was long a tedious for me. Makes no difference if it is one caliper or two.

Mechanically, a hydraulic system is simple. The fluid makes it messy. Getting rid of the air; tedious.
However, there are some details that you should think about. For instance, how to get the pistons out of the caliper. You can push them with the fluid (very messy, they pop), or you can do it cleanly with compressed air.
Draining all the fluid is OK, as it should be replaced anyway. Nevertheless, be advised that the brake lever is an extremelly slow pump, like an hydraulic jack. It will take you very long to fill it back, unless you use a brake bleeding Vacuum pump ( ~ $40.00).
You could chose to keep most of the old fluid initially, by hanging the hoses higher than the MC, while working on the calipers. Getting rid of the air will get thru several bottles of fluid later anyway.
Google, brake caliper overhaul....order your seals and banjo bolt washers in advance.

Clutch, I just picked up mine the other day too. Looks same as yours but black. Did you check out the link on my other post. Someone is selling a service manual on CD for $8.99. I haven't gotten mine in the mail yet, so i can't say if its any good. Seemed pretty cheap though.
I think I'm going to go with the Clymers, but definitely let me know how the disk is. I plan on keeping this bike for a long time so if it's good, I'll get one of those too!
