Cruising down the a main road at about 65-70mph, I felt the 636 start to drag. I quickly switched to the outside lane and pulled in the clutch when....the front brakes completely locked up sending me over the bars, onto my shoulder and sliding down the road. And now, to our feature presentation.

Bike: 06 zx6r with cheap frame sliders, recently installed ss brake lines & hh pads.


The gear: alpinestar tz1 reload jacket, jeans. Virtually untouched gear:alpinestar boots & gloves. Scorpion helmet.


The jacket held up great and I will be getting another one for hot weather riding. Still saving for some leather pants and yes the previous leg scar is from a soccer game and was worse than my battle scars. Time to ice my shoulder, cover my wounds and have margaritas with my wonderful women while surfing the net for parts.

Gear up and be safe family.

Glad your injuries are relatively minor..... that can't be the outcome you expected from upgrading your brakes.

I have to presume your pads were touching the rotors and heated up the fluid to the point where it expanded and locked the brakes.

Did you get all the bubbles out of the lines?

Did you clean the pistons in the calipers before you put everything back together?

What brand of brake fluid did you use?

Do you have aftermarket levers?

Yes, the front pads were dragging (after the install) so I cleaned the calipers, bled them again and went on a couple of test rides. All seemed well until today.

That sucks man, sorry to hear this. Def sounds like the brakes were dragging, excess heat continued to build up and expand the brake fluid, and the brakes eventually locked.

Maybe the pistons were sticking due to bad seals, dirt, grime, etc. I recommend you fully take apart those calipers, clean them, and replace any seals that are bad.

Not sure why they locked up. Everything was clean, no bubbles in the line. I did have to crack open the bleeders to push the pistons back far enough to get the new pads in. The calipers, master cylinder and levers are all stock (for now). Any suggestions on front caliper rebuild/replace aftermarket/replace with same or different year?

Damn thats scary but at least ur not hurt too bad. Dont the 05/06 bikes have an issue with the master cylinder which cause the brakes to lock? Ive heard this same thing happening many times before.

Holy Smokes Mang! Good to see that you walked away with minor injury. I would double check to make sure you mounted the front wheel back on correctly. I haven't taken my Kawi front wheel off yet so, I am not sure if Kawasaki uses front wheel spacers.
I did make the mistake on my 2001 Honda CBR 929 of note putting the wheel spacers on the correct side. It resulted in brake drag but, not lock up. I swapped the spacer and wheel spun freely again. Hope for a speedy recovery and a quick repair of your bike.

There is a known issue with the 05/06 MC but the issue causes the system to lose pressure which results in a soft lever. Have never heard about it causing the brakes to lock.

I would suggest you go the same route that myself and many others went and look for a set of 07-12 ZX6 calipers which are a direct replacement. They are supposed to be much better and can be found cheap on eBay.
