hi guys

I was wondering if anyone knows of any common faults that to spongy brakes. ive have bleed them 3 times using a presure bleeder and there isnt a air bubble in the lines.

The brakes themselves work fine once they bit but there seems to be an inch or 2 of spongy movement then the brakes kick in but they then lock the wheels fine?

thanks Ali

Brake pull rod needing adjustment, faulty flexible hoses, too much pad knock off caused either by faulty calipers or discs, faulty master cylinder. Take your pick.
