I recently had my forks rebuilt & rechromed. While my bike was off the road, I overhauled the front & rear braking system. I have replaced all rotors and pads and also removed all caliper pistons and replaced the 2 rubber seals per piston with parts from Impex. Pistons and bore were in good condition. I admit to cheaping out and buying this triple set of organic pads for $37 About the only thing I did not do was to replace the 2 copper? washers per banjo bolt with new. All banjo bolts and nipples are firmly tightened. Now that the bikes forks are back on and I have taken for a test run, I have found the front brakes to be very spongy. I have bled the front system 3 times now. I have noticed that the front brake lever will almost touch the rubber handle grip on the first squeeze. After pumping the lever a few times in succession, it then feels more normal and is about 2 -3 cm away from handle grip whist held in. But after releasing the handle grip and waiting 5 seconds and then squeezing it once only, it again almost touches the rubber handle grip. I have not touched the master cylinders, apart from refilling them whilst bleeding. Fluid level has never got so low that air has entered. No air bubbles are apparent in resovoir or the clear plastic bleed lines. The brake fluid DOT3 was new from an unopened container. Any ideas what may be the problem? I have a hunch that air is somehow entering the system, but I cannot see how.
