Today’s cars have so many refinements that it’s no wonder we love to rent a new car when we travel. But back to our old cars, and you almost immediately feel a difference just backing out of the driveway. The modern braking system, especially with ABS, not only provides more confidence but it also provides peace of mind.

Classic cars, however, have become a different story when it comes to braking. After stepping out of that modern car and into a classic car, we often find that our brakes require a little more effort, and sometimes that can be a problem. Master Power Brakes is here to show us in the video above what to look for, and how to check your brakes for potential problems.

We all know there is a myriad of problems that can befall your braking system, compound that with rear drums and you’ve brought it to another level. One issue that MP Brakes’ Mark Chichester tackles in the video above is the hard pedal feel, and what to look for.

An engine needs to produce about 18 inches of vacuum for the brake booster to function properly, and low engine vacuum will give you that hard pedal feel. One of the first items Chichester suggests checking is the hose itself, and to make sure that proper vacuum line is used, not fuel line. Vacuum line is designed to keep the hose from collapsing

Another simple method to check is to press the brake pedal a couple times prior to starting the car. Then hold the pedal and start the car, once vacuum develops it should soften the pedal, and it should drop slightly. If it does, then you know that your brake booster is functioning as it should.

Chichester moves on to check the rear wheel cylinders, combination valve, or the check valve on the booster itself. Of course, if you have any questions about the way your brakes function, or you’re seeking an OE-style or big brake upgrade, check out the Master Power Brakes website, or give them a call for more information.
