So I just took the bike for a quick ride on this little turn track near the house.
About five minutes in the rear brake completely went away; no pedal. Didn't see any fluid leaking or anything damaged, but I still wanted to ride so I said I would figure it out when I got home.
Couple minutes later the front brake completed locked up. I could feel the lever getting pretty stiff and when I stopped to check it out, the wheel was locked up. Again nothing looked damaged and I had to push the bike 1/4 mile back to my truck with a locked up front wheel...talk about a work out. Anyway, by the time I got out of my gear and was ready to push the bike up my ramp into the truck, the front wheel was no longer locked up. Still had no rear brake.
Could I have heated the front brake up that much to the point of it locked up the front wheel? I wasn't riding hard at all, mainly in first gear hitting a couple turns nice and easy. Since I was already out of my gear and it was getting late, I didn't ride the bike again. Honestly, I'm not sure if everything is fine. I'm afraid if it happens again and I'm hauling around a track, I'll get sent over the bars and it won't end well.
Any thoughts?
Thanks.

Otherwise check all the sliding pins for corrosion and straightness. And if those were good I would pull the pistons from the caliper any give them an inspection. And fresh brake fluid for sure.
Brakes are a safety item so if you are unsure about anything let someone qualified handle it.
Keep it simple... Bleed your brakes, inspect your wear items and like fulltime said, check your pins for corrosion.
Use DOT 5.1 as it has a higher boiling point, and make sure that you "flushed the system with the new fluid. Mine ended up warping the little rubber seal on the dust cover and had to buy a "rebuild kit" from KTM usually around $40.

One question, as you push in one one piston, the other piston should move outward correct? Basically, as one piston moves in, the others moves out and vice versa. I'm guessing that ensures even pressure on the pads and disc?
Thanks again
