HALP! Front brake problem. CBR600 F4

Hi all just wanted to see if i can get some input on a brake problem. Ever since i got my bike when i try to brake using the front i get a really noticable jerk almost like ABS on a car. The brake level is fine and the pads were replaced by the previous owner. Any ideas why its like this?

Thanks in advance, Dave

If it is pulsating then I would look at the rotors, but if it is one jerk when you apply front brakes look at the neck bearings.

Yes. The symptoms of a failed bearing could be perceived by some as a brake issue. The rotors could be warped as well.

Didnt think about the neck bearing....I've never experienced that problem so I don't know what symptoms to look for....take it by motorcycles unlimited and have them diagnose it for ya

Its more likely that it's the rotors. Given the age and make of the bike there is a chance its the bearing.

Step 1 put on stands.
Step 2 Spin front wheel while barley applying brake Look for wheel to get tight then loose then tight then loose. If so....warped rotor. If not move to step 3.
Step3 Put bike back on ground, hold brake lift off seat rock bike back and forth (quite hard) on handle bars. Feel for "give" or "clicking". If so remove top triple retourqe neck nuts, if not, move to step4.
Step 4 remove front wheel and fender and brake lines. Grab bottom of fork and try and push up, also pull down. If no play ( you should not beable to compress forks by hand like this) reassemble.

Wow thanks for the input guys! I now leaning towards the rotors. It most certainly feels like it releases for short bit then again engages. Ill post a result.
