Tech Talk with Master Power Brakes

Picking the Proper Vacuum Hose For Your Brake System

Posted by toby 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?”

Since we are in the brake business, we notice more things when it comes to a vehicle’s braking system than most classic car enthusiasts. Kind of like the house painter that can’t walk into a room without checking the paint line between the wall and the ceiling.

So what was it that our resident gear head noticed? About half of the vehicles he saw had a power brake booster with the wrong type of hose going from the engine vacuum source to the brake booster.

Adding Horsepower?  Don’t Neglect Your Brake System

Posted by toby on Jul 30, 2015 2:51:35 PM

Make no mistake about it, most classic car enthusiasts like to go fast.  We spend countless hours in the garage figuring out ways to go faster.  Adding more horsepower guarantees you’ll impress your buddies and have a blast every time you pull away from a red light, but that extra giddy-up can cause some problems too.

Bedding In Brake Pads and Rotors

Posted by toby on Jul 30, 2015 10:23:35 AM

We just received a question from a customer asking about the proper bedding procedure for his new Rallye Series front disc brake conversion kit.  Regardless of which kit you select, it is a good idea to bed or burnish the brakes to transfer an even layer of friction material to the rotors.  Taking this step will ensure smoother, quieter braking and enhanced stopping power.  If you bring the new pads and rotors up to temp too quickly and/or botch the cool down period, you may experience glazing on the pads and poor performance.  Proper bedding ensures a uniform coating of pad material is applied to the rotors.  So, how do we properly bed in new pads and rotors?

Can I Use DOT 5 Brake Fluid With My New Brake Kit?

Posted by toby on Jun 24, 2015 9:31:48 AM

The owner of a 55’ Ford Sedan just sent us a note asking why we don’t recommend using DOT 5 brake fluid with our brake kits.  Chances are good some of you are asking the same question, so this post is designed to clear up confusion about the different types of brake fluid.

If you cruise over to the local auto parts store, you’ll see all kinds of brake fluids in the aisle.  DOT 3 is always the cheapest option—DOT 4 is about 50% more expensive than DOT 3 and DOT 5 is about two times more expensive than DOT 4.  Some owners mistakenly assume that the higher cost of DOT 5 equates to better performance, but this is not always the case.  In fact, sometimes the exact opposite is true.  To get a better handle on why we don’t recommend DOT 5 for our brake kits, we need to take a crash course in chemistry.
