I installed Spiegler SS brake lines on my bike and the brake lever travel is quite long before the brakes start. I have bled the living hell out of those lines and there is no air to be found using a traditional brake bleeding tool (tube with metal fitting that allows air to travel in only one direction). I have bled repeatedly at the caliper and the MC.
I checked that there is no fluid leaking anywhere in the system and the brakes do work - albeit awfully. I have read about bungee tying the lever over night and then bleeding the following day as air bubbles should make their way to the bleed nipples (I believe mainly the MC nipple). Should I try this - can any harm happen and how hard should the bungees pull on the lever)?
Are there any other methods for getting out pesky hidden air bubbles in the system?
I have also read about cleaning the calipers and the brake pads - is it worth trying? While I am sure this could help, the fact is the brakes are spongier now than they were with stock lines so something happened as a result of the install.
Somebody else wrote to loosen the caliper mounting bolts and almost take them off but not quite and while the pads are barely touching the rotors to pull on the brake levers because "the seals for the pistons in your calipers are flexing too much instead of letting the piston slide" - any merit in doing this?
Thanks.
