It looks like I've got a sticky or seized piston on one of my front calipers so I'm going to take both the calipers off and get all the pistons out for a good clean up. It's not a problem, I usually clamp 3 of the pistons and pump air using a foot pump into the caliper to blow out one piston, clean it up, put it back in and then do the other three similarly. But, for the life of me I can't remember how I used to connect the pump into the banjo bolt hole, I have a vague recollection of using a schraeder valve (from an inner tube) and a football inflator (or was it a 'bic' plastic pen cap) but can't imagine how. Somebody who has done this will know what I mean, I'd be grateful if someone could remind me. Cheers
