Re: Master cylinder connection

If the bore for the front and rear pistons is the same size then either one will activate the rear brakes with similar force. If you have disc front and drum rear I believe it is better to connect the front brakes to the front port. The tandem master cylinder doesn't apply significant pressure to the front port until the rear chamber has built pressure. Connecting front brakes to rear port applies front brakes slightly sooner and generally builds pressure faster to apply rear brakes.
