I'm hoping somebody has some suggestions for me. Here's the background:
I purchased a new 914rubber master cylinder back in 2017 (doesn't seem that long ago though). It's been working flawlessly, and I only put maybe 200 km per year on the car. I stored the car over the winter, and this spring when I pulled it out, I had zero brakes. Brake pedal would go to the floor with no resistance. There are no leaks that I could find, and the brake fluid reservoir was still full. I was thinking maybe the master cylinder piston got jammed open with some crud from the pedal side (the boot isn't really a tight fit), so I pulled it out and took it all apart, cleaned it and rebuilt it. Seals and everything all looked good. Put it back in, and still the same issue. I can always buy another master, but it seems like such a weird failure considering the dual independent circuits. Any thoughts? Thanks in advance! |
