Having problems with my front brakes. Fronf left brake was binding so removed caliper including hydraulic feed at banjo bolt. Tried to get seized pistons out of caliper no joy so replaced banjo hoping to pump them out with brake pressure. Did as suggested in the manual but cant seem to get any pressure back in the system!!!!! Driving me nuts!!!

As you'll have to bleed the system now you might as well order new seals, take calliper off, soak in wd-40 (I have posted a thread on how to make your own wd-40 somewhere), anyway, take both bleed nipples off (these are most likely seized hence lashings of wd-40, this will equalise the pressure inside the caliper (the suction is whats holding them in), if you have an old small speaker use the magnet, stick it to the piston to help you ease the piston out while tapping the calliper with a nylon or wooden mallet, or you can carefully dig out the seal and replace with a new one.
