Chevy guy with a Mopar? hmm...

Welcome. Brakes..........If the rest of the system is properly set up, you will probably find you don't NEED power, and may not want them. Now I'm an old guy with arthritis--65, and mine has the popular 73/ later front disc conversion, and while many guys on here are successfully using various rear drum brakes, I have a Versailles rear axle with factory disc brakes, so 4 wheel discs. The factory master (manual) causes this thing to stop just FINE, and I do MEAN.
