Simple Dimple! Only bummer about this job is that nobody sells the seal kit locally from what I could find. The main seal is just a rubber grease style seal (no metal or plastic ring) and the figure 8 seal isn't necessary, just light as well swap it while you're there. This was fast and easy and my first time ever ripping into a hydraulic booster. Cake. Walk.
