chakka Posted May 31, 2007 Posted May 31, 2007 My 88 FZ600 has a sticky feel when the front brakes lever is pulled. I pull it in and it sticks, then I can pull harder and move it some more then sticks, etc. Any info on what I can look for is helpful.
BULLDOG Posted May 31, 2007 Posted May 31, 2007 Sounds like your caliper pistons are sticking. Try giving them a decent clean with brake cleaner once you've removed the pads. The pistons should be nice and shiny. I often have a similar problems due to dogs who mistake my front wheel for a lampost...

The pistons that push the brake pads onto the disc will most likely be very dirty and have filth stuck hard to there sides. You need to take the pads out, take the top off your brake fluid reservouir (try to put o bit off cloth around it to stop fluid spilling/splashing onto your paint work!!) pump the pistons a good way out (but not all the wat out!!) and then clean arond them. Best way i find is to use a bit of clean brake fluid and some very very fine sand paper cut into long thin strips.... put a strip around the piston and pull the one end of the paper then the other.. in a kind of back wards and forwards motion to clean around them, making sure all the time that the sand paper is nice and damp/wet with the clean brake fluid. Do this a little while till you get them nice and shinny/clean. then get a couple of strips of clean cloth and try to dry them off and buff them at the same time using the same kind of motion... then push the pistons back in, makeing sure that as you push them back in- they are going in nice and strait with a good even pressure all around. Do this to all the pistons on both sides of the bike, then pop your reservouir cap back on (topping it up if need be) Be advised.. its not a quick job!- take your time, and the better job you do... the better they'll feel when you come to use them! also before riding the bike, pump the lever a good few times to get some pressure back and try them out a bit at a time... like bedding in new pads type of thing. Hope this is of some help, let us know how you get on, cheers, Dave.

Thanks, I suspected as much, but thought I'd throw it out there for confirmation. It'll be a good learning experience for me. Plus the weather this weekend is supposed to be rainy anyway. I'll post how it turns out.
chakka Posted June 20, 2007 Author Posted June 20, 2007 I ended up just flushing the old fluid out with new clean fluid and the problem is gone. Thanks for your advice guys.
