Rear master cylinder leak?
Noticing that when I engage the rear brake, I'm getting small bubbles of fluid leaking out around the boot on the master cylinder. I'm on the low side for fluid level, but I've never changed it (actually noticed this when I was looking at the system in preparation to change it). My brakes don't seem to be affected. Should I just change the fluid and watch the level, or is this a warranty issue that needs to be addressed ASAP?
