Hello, I feel like I have read all the tips and tricks on the spongey/springy KTM front brake. I've got an 05 250 EXC and last summer I lost my rear brake during a ride, so I decided to do some maintenance this winter on both front and rear. Rear brake went smooth, new pads, rebuild kit on mc and caliper, fresh fluid, new lever bearings. Rear brakes now work great, but the front brakes are spongey/springy. I've tried just about everything from zip-tie to tapping on the caliper when bleeding, back bleeding with a syringe and traditional bleeding. What I am noticing now is, my lever gradually gets firm as it is pulled in but can still pull to the bar and never gets solid (the adjustment is all the way in so there is no free play), what I am seeing and hearing is the caliper kind of creak and flex. Note that this is just in the shop, not during movement. I've never had issues with bleeding brakes and I am 90% sure there is no air in the system. I'm about to the point of getting on ebay and getting a Nissin MC. Any suggestions on what to try before I try a Nissin? I'm not sure how I still have hair! Thanks!
My 2011 KX450 has had a spongey front brake ever since I got it. I recently decided to rebuild the front master cylinder, replace brake pads, put on a steel braided line, and then clean out the pistons and seals in the caliper. And it is still spongey!!! I’ve bled the crap out of it, no bubbles, everything looks great. Both pistons in the caliper seem to work fine. I don’t know what else to do other than spend $400 on a new caliper which I don’t want to do. Any suggestions?
