67 Dart 270...Project Old School

On my way home from the Bonne Terre Drag Strip, my brake pedal began to get soft and I was having to pump the pedal a time or two to get a firm pedal. When I got home I made the decision to replace the 47 year old (stock) master cylinder. Since I had upgraded to discs on the front I ordered a master cylinder for a 67 Dart with manual disc/drum brakes.

Here is a picture of the rare option "Invis-O-cast" master cylinder. They use a lot of the same technology today in stealth jets ;-)


Yes,...it has been a long time since the last time a swapped mater cylinders. My 10 year old son helped me bleed the brakes. He got a work out pumping the brake pedal, while I was under the car taking a brake fluid shower. The results were outstanding! The brake pedal feel was vastly improved over the stock master cylinder. I always love the small projects that have positive results.
