I’m installing the new hardlines for the rear brakes on our 2009 Mini Clubman S, the ones that connect the rear brakes to the connectors at the front subframe. I bought generic “European line” from the Autoparts store, and they were fine at the rear, but when I get to the front of the car one of the outlets from the brake system is larger than the other and does not fit the fittings at the end of the brake lines I bought. I’ve never seen this, is there a step-down adapter?
