Fitted some st202 brakes to my glanza, when I changed one of the calipers over I left the brake line unhooked for about 15 minutes obviously taking in air and loosing brake fluid. I've now bled all four corners multiple times and keep getting air coming out, does anybody have any idea what is going on? Have honestly bled them around 10-15 times now and it's just stupid. The pedal has about 40mm travel before it actually catches and starts braking!
