New set of above brakes. Fitted front, re bled due to hose shortening with zero issues. Fitted rear and also shortened hose but can’t get rid of the air bubbles. Been through a full small bottle of dot 5.1 but air bubbles still coming through. So tried trimming the hose a bit and more new fittings at the lever end. All tight, no nicks and no evidence of leaks anywhere in the system.

Where is the constant stream of air bubbles coming from???

Normal hope system for bleeding.

Just had word from Hope they suspect a faulty master cylinder piston seal.
