Successful Failure

***This post focuses on heavily modifying the power brake vacuum booster. DO NOT ATTEMPT ANY OF THESE MODIFICATIONS. This is to be read for entertainment only. Tampering with the factory structure could lead to brake failure and can endanger your life and those around you.***

I managed to seal all of the cracks but when the wedge is bolted on and removed, more cracks are created. This puppy is toast.

However, even with a leaky booster, I am still able to assemble all of the pieces to see if this exercise paid off.

There are no instructions for any of this stuff. I’m not sure how it goes together, so to start the test fit off, the wedge is bolted to the firewall just to see how it looks and to see if the holes all line up

As simple as all of this looks, it’s pretty exciting stuff for me. I don’t know for certain if what I read about and hypothesized on would really work. So far the wedge bolts on with just some very minor work. One hole had to be slightly elongated.

Now for the big moment.

Assemble the booster with the wedge attached and the master cylinder installed and get it bolted into the car.

and it really fits. Can you believe it?

You know? Functionally, as a vacuum booster, this booster is a bust but as a physical working example of something I’ve been guessing at and now that all of the theoretical Boss brake parts are bolted together and in the car, and it’s clearing the engine as I was hoping it would. This is an awesome moment.

Ok, the moments passed.

Now I have to see if I can make one that will actually hold vacuum.
