1977 KZ1000 Sticky Front Break

Hi All

First an introduction. I am just back into Z's after 20 years on four wheels. I went and purchased this beast imaged below last weekend.

So I have all winter up here to get things tuned up.

First up is a sticky from caliper. It seems that it will not release the wheel after a couple of squeezes. Is there something easy to try before I start pulling the system apart?

Thanks
Chris

I'd start with pumping some clean brake fluid through the system. Your symptom is usually either a plugged return hole in the bottom to the master cylinder reservoir or gunk between the piston and the caliper.

Brother, that bike is beautiful. Please don't be tempted to cut it all up.

Thanks ! -- My goal is to keep it stock as can be. The side covers are the only issue cosmetically right now. They became blue along the way,

I will try to run new fluid through and see if that cleans it out. Ill post back.

Cheers
Chris

Sounds like time for a caliper rebuild. I just did a spare for the rear of mine even though my two front and single rear have all been rebuilt.

Welcome from East Tennessee!! :woohoo:

Dusting off my old thread here.

I have the caliper off and apart. Lots of crud in there, so may explain a lot. Going to put a rebuild kit in, as the caliper bolt dust covers are gone.

I already purchased a kit for the master cyl. Even though it appear ok, the break fluid was pretty gritty, so I want to start out now with everything fresh. I am now stumped how to remove the circlip that sits in front of the C Clip.

I am refering to the lower middle part in this image here;

I have the "round" master

Any advice there?

Thanks and Happy New Year

Part number 19. I cant figure how to get it out of there?

Without having it in front of me, it looks like a sharp pointed knife or an awl could be used to spring it inward(while keeping the plunger partly depressed) so you can slip a small blade screwdriver under it. Be careful not to lose it if you need it and Good luck. I have rebuilt my calipers, but not my master as it was already changed out by previous owner.

Thanks...I have been poking / prying at it with an awl for a while today. Its starting to look like one of the things that require a nights sleep to resolve.

Sharpen an old small screwdriver(smallllll) and give it a try while keeping the plunger depressed slightly. Just make the screwdriver blade really flat and pick at it.
