I broke a plastic hose that's part of the brake booster system on my Cayman while replacing the clutch, and I received the replacement part today but cannot figure out how to remove the old one. It runs from the front of the left cylinder head over to the left rocker panel where it goes forward to the brake booster. It attaches to another hose a few inches forward of the rear wheel well with a white plastic connector, but I cannot see any way to get the connector to release. I've pushed it, pulled it, twisted it, but nothing gets it to release. The replacement hose has a step about 1" from the end that this connector goes over to lock it in place. Is this like some Ford and Chevy fuel line hoses that require a special tool to release it?
