So the other day I rode to work about 30 miles. Got there without a hitch. Went to leave and noticed that the bike would not roll tried to move and nothing. Come to find out my front calipers were locked up. Got a wrench and bleed the pressure off and Limped it home. Now I'm wondering what the hell is going on the bike is a 07 cbr 600 rr with only 2000 miles on it. Bought the bike in the beginning of the summer with less then a 1000 miles on it. Not sure if the fluid was ever changed or not but am going to do that now along with lines and pads. Is there anything eles I should do? Has this happened to anyone? Sure glad it didn't happen on the highway.

 

Anyone got any ideas why this happened.

 

Your caliper may have a seized piston? Which gets stuck and would not retract. Or maybe you have a warp disc rotor? But that's may seem odd.... scary issue here & best to have brake system thoroughly checks...

 

My guess is a stuck piston. If its a 07 with only 2k miles on it im guessing it sits a lot. So there is most likely a little bit of rust stopping the piston from retracting. Its a easy fix that you can do yourself.

If you need the know how let me know.

 

I was thinking something like that . Got the rebuild kit for both calipers (seeks and dust seals). Going to break them down this weekend and lightly sand the pistons to get off any surface rust.

 

I find it odd that both calipers would just lock up at the same time after being parked for a day. Did they both have pressure just sitting there? An internally collapsed brake line or a faulty master can keep pressure on both calipers.

 

Haven't added aftermarket levers? Common cause also.

 

^^ Solid.

 

had same problem. poped outthe pistons cleaned them bled the brakes and was fine. now my wheel spins all the way around not just 2 inches

 

im with the rebuild. a bike thats seen as much milage in 4 years as i put on my bikes in 2 months....is sitting WAY too much. you might be in for more than that in the future. might wanna tackle the rear caliper at the same time
