People who are helping diagnose certain brake problem conditions - in particular a hard brake pedal - often suggest that you measure the vacuum pressure. The advice will sometimes mention that your engine must produce more than 18” of vacuum to give that nice easy pedal feel. In fact, we just provided that explanation in our recent Tech Talk article on diagnosing causes of a hard brake pedal.
We started this 4-part series examining possible vacuum pressure as the cause of a hard brake by picturing a driver's inability to apply his brakes in traffic because the brake pedal is too stiff - requiring an inordinate amount of pushing power. An extreme scenario for sure, but the horror of a hard brake pedal can strike at any time. In power booster equipped vehicles, the issue is more common than you may think. Fortunately, you don’t need a degree in Rocket Science to diagnose and fix the glitches that are hardening your pedal.
Converting from manual to power-assisted brakes is a major upgrade and one of the most common projects that we discuss with customers. Due to the different size requirements for brake boosters and master cylinders, you may need some help sorting out the available options to optimize your vehicle’s brake system performance. That’s where the tech pros here at Master Power Brakes really shine.
Most classic car owners fall into one of two camps. On the one hand, we have a small minority of owners with rare, museum quality cars. In most cases, these folks are reluctant to make any changes to their cars because even the smallest modification means losing an important part of automotive history. On the other hand, we have classic car enthusiasts that modify their vehicles for better performance and safer operation.

We recently received a note from the owner of a 65 Mustang asking us to justify the cost and expense of converting his car from drum to disc brakes. We field this question on a regular basis, so we thought it made sense to share our thoughts with our readers.
