master brake cylinder swap
 

As I started to drive out of my driveway, today, I lost all brakes. I haven't had time to check it out but loss of all brakes is normally a master brake cylinder failure. I have a spare master cylinder from a 05 STI. Will it directly swap to the SVX or even if it fits, is it up to the task of exerting enough pressure to effectively stop the SVX?

ANY leak in the brake system will cause all braking to go out. Check for leaks first and then move on from there with diagnostics.

I'm going to check it out today but I was under the impression that we had a split braking system so that if the front/ rear leaked we would still have two wheels to stop the car.

I'm not sure how our brake system works, but when I had a leak in one of my rear hoses, I was still able to brake. It can't hurt to check all the brakes anyway.

Lose of all breaking? How about the brake booster, vacuum leak?

Jvan,
first check the brake fluid level,
then look for leaks in front of both rear tires.
