One noticeable difference between hitting the brakes on a late-model car and an old Chevy is the under-floor-mounted master cylinder of the earlier car. After driving a car with swing pedals for so many years, it can feel a little awkward to apply the brakes in a car with through-the-floor pedals.
If you're looking to improve the driving experience of your '49-54 Chevy and aren't worried about completely smoothing the firewall, then Walton Fabrication might have just what you're looking for. Their new Firewall Mounted Power Brake Assembly can easily be installed in an afternoon including running some new brake lines. We recently dropped by as they were fitting one on a customer's '49 Chevy and shot a few photos for you.

The 8-inch single-diaphragm vacuum power booster was then installed using the lower four holes. The unit is now bolted together to form a solid mount.

The pedal was installed using...

The pedal was installed using the supplied hardware at its pivot point at the top of the bracket. The adjustable booster pushrod was then bolted to the pedal.
