The MOT tester said the brakes were binding and suggested replacing the seals. After doing that I bled the brakes following the instructions in the Haynes manual, but the brakes still feel spongy and I can pull the brake lever right back to the handle bar. Does anyone have any ideas what I've done wrong or suggestions for what else I can try?
I also noticed that when operating the brake lever once, the pistons don't all move equally, the small piston on one side of the caliper and the large piston on the other side moved out while the other two pistons hardly moved at all. Cause for concern?
you can also try to bleed the brakes at the banjo bolts.
