Hey was hoping you knowledgable chaps could help out here... Hope the answer's straight forward but i took the front wheel off the bike today to grease up the bearing, doing so i pushed the front pads apart on the caliper to make refitting easier. Anyhow, long story short on refitting and pulling the level to push the caliper piston out, both brake lever feel and braking force has deminished. Both pads are pushing onto the disc good enough to lock the front up when pushing the bike but when riding the front brake literally has no force to be effective. There's no fluid loss, master cylinder's topped up and have just bleeded the brakes with no air coming through. What can be the problem? i did hear like a surge of fluid when pressing on the level after the the fitment of the front wheel, but no loss of fluid as far as i can see! Thanks!
