Have a 99 cbr600 race bike.
original problem last season pad binding on disc and spongey feeling in cylinder.
So did a complete overhaul on it rebuilt calipers new lines and a radial cylinder from a gsxr 1000. Things are way better already wheel is spinnin freely and good bite but theres still sponging in the cylinder even tho we have bleed the life out of it. but iv noticed theres a heap of movement in the disc and pads like the disc is springing. Any other things to look at? thanks
