I have searched the forums and tried about everything I can think of to fix my non-working front brakes. There is no pressure in the brakes, brake lever goes directly to handlebar. I have taken everything apart from the front brakes and cleaned them. I replaced the o-rings in the adjusters because they were in bad shape. I have bled the brakes from the master cylinder down and attempted from the brake area back up to the master cylinder. I removed and cleaned the master cylinder, then ordered a master cylinder rebuild kit and installed that tonight( then bled brakes again). I cleaned everything in the master cylinder area, including taking a wire to clean the small hole in the master cylinder. I replaced the brake pads (but not the springs). I have adjusted the brakes before and after the pads were replaced. I don’t see any leaks in the brake lines. What are the chances that the brake cylinders are bad? The right side seems to bleed better than the leftt side, but neither side seems to have the pressure to push both sides of the cylinders out. When I cleaned the brakes the first time they were pretty muddy, I have 2 kids that like to ride in the mud. Any suggestions are appreciated!
