Over the past month, I've started experiencing intermittent pedal drops that are becoming more frequent. The pedal now also engages/resists at a slightly lower point than before. I took it into the shop and they confirmed it was likely a master cylinder issue. At a service quote of $1700 - $2200 to replace, I figure I'd do it myself. Since I have a 2010 with a metal cylinder, should I buy another factory metal cylinder or the Wilwood kit? It looks like BOE has a kit as well for the same price as the Wilwood but has anyone here installed it? Would it make more sense to see if bleeding the entire system works first?
