Selecting the Right Booster/Master Cylinder Combo For Your Classic Car

Posted by Master Power Brakes Team on Jun 28, 2019 2:31:11 PM

If you are looking to convert your current manual brakes to a power system, you are probably wondering which Master Power Brakes Booster/Master Power Conversion system to choose. 

Some applications are pretty straight forward as there is only one option, but we see plenty of situations where two, three or even four different options can work.  So which one should you choose?

Picking the Right Proper Vacuum Hose For Your Brake System

Posted by Master Power Brakes Team on Sep 4, 2017 8:00:00 AM

Because we are gear heads, we take every chance to look under the hoods during car shows and swap meets.  One of our guys just got back from a big show and he was surprised by how a mistake he saw so many times. 

To use his words, “How could something like this be wrong on so many vehicles?”

Hard Brake Pedal | Poor Brake Performance | Try Measuring Engine Vacuum

Posted by Master Power Brakes Team on Apr 2, 2016 1:34:11 PM

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.

Is a Master Cylinder Change Required in Drum to Disk Conversion?

Posted by Master Power Brakes Team on Mar 21, 2016 5:01:35 PM

We have been asked a number of times if there is such a thing as a manual disk brake conversion kit? The simple answer is yes. The power booster component almost exclusively affects how your brake pedal "feels" to you under foot.

In a situation where your classic car has multiple drivers, some of whom are used to the "foot feel" of power brakes - maybe they spend most of their time driving a newer car or light truck - a power-assisted brake pedal can makes it easier to go between vehicles. The power booster allows you to maintain relative consistency with how much pressure to apply when stopping either of the two vehicles.

You DO NOT NEED to upgrade or convert to a power assisted apply system, however, when making the upgrade to disc from drum brakes. Recently, we got an email from a customer planning on making that drum to disc brake conversion but interested in sticking with a manual set-up.

"Dave" has a '66 GTO he uses as a daily driver and wanted the enhanced performance and stopping ability of disc brakes. But as the sole driver of the car, Dave was comfortable with the pedal effort the manual brakes currently required and wanted to keep that same level of brake feel.

Valving Issues Related to Hard Brake Pedal

Posted by Master Power Brakes Team on Sep 9, 2015 7:37:33 AM

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.
