How To Install a Power Brake Booster
Master Power's Power-Brake Conversion Can Be Used With Stock Drum Brakes, Stock Disc Brakes, Or MP's Disc-Brake Conversion Setup
Installing front disc brakes is one of the most popular upgrades for vintage Mustangs. We've covered the subject several times throughout the years and with good reason. From a pure safety standpoint, converting to front disc brakes is about the single-best improvement for your older vehicle.
Several companies offer drum-to-disc conversion packages. This month, we're touching on a Master Power system being installed on a '70 Mustang. However, this time we're closely detailing the MP conversion to power brakes.
While installing the whole setup at once is a great way to go, keep in mind that there are several options. If your '67-'73 Mustang already has manual front disc brakes, you can install the booster and corresponding master cylinder we're showing here. Conversely, if you have manual drum brakes and want to do the power-brake conversion first, that's also possible, although putting in the discs first is probably a better idea should you need to budget the project over time. The power booster will work equally well with either drum brakes or front discs.
For '65-'66s that came with manual drum, power drum, or manual disc, Master Power also offers complete power disc kits that are great for updating these cars.
For the installation, we turned to our friends at Marlo's Frame and Alignment, who supplied the extensive installation knowledge for our project.
Also note that while the power brake booster and master cylinder is an excellent upgrade and works beautifully in our '70 Mustang subject car, it's not easy to install, mainly due to the fact that the brake pedal must be changed. With two experienced techs working on the car, it took about 10 hours to do the conversion. Working at home, figure on a full weekend to install the booster and master cylinder. The results are definitely worth the effort.
