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.

How To: Diagnose and Fix Brake Drag

Posted by toby on Jun 5, 2017 4:20:00 PM

Whether you’re installing new brakes on your classic car or working on an existing system, brake drag can be a frustrating and challenging thing to diagnose and locate. On a positive note, the problem is usually a pretty simple repair once you find the culprit.

What Is Brake Drag?

Brake drag happens when the brake pads or shoes don’t release completely when the brake pedal is released, and is typically a result of mechanical issues or hydraulics. It is highly recommended to fix the dragging brakes as soon as possible, because it can lead to overheated parts and potential damage to the braking system, or worse yet, an accident.  

Referring to the checklists below will help you identify and repair your brake system’s brake drag woes so you can get back out on the road.

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.  Every time you play a little at a red light, the next stop light shows up faster than it used to.  You could try cruising in a different part of town, but where’s the fun in that?  The bottom line is simple—that extra horsepower may require a brake upgrade to maintain safety.

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?

June's Ride of the Month: Herb McCurdy's 1963 Plymouth Sport Fury

Posted by toby on Jun 30, 2015 11:12:46 AM

We want send a special shout out to Herb McCurdy--the proud owner of a 1963 Plymouth Sport Fury and June's Ride of the Month.  Herb didn't just send us awesome pictures--he also did a great job detailing how he gave new life to a timeless classic.  Here is Herb's story...in his own words:

[gallery link="file" ids="886,887,888"]

I had been looking for a 63 Plymouth B body to make a Max Wedge clone for a while when I came across an ad in the local St. Louis news rag for a 63 Plymouth and made the call. To my surprise when I went to look at the car, it was a very solid 1963 Sport Fury numbers-matching survivor. Well, their goes the Max Wedge plans, as I could not bring myself to do modifications to such an original car as this one! It had a solid rust free body with original paint and a nice set of paperwork to boot. After passing muster with the owner as she was fussy as to whom she would sell the car to, I negotiated, and we agreed on a price. I was now the new proud owner of a 1963 Plymouth Sport Fury Convertible that needed a medium to heavy restoration!So the 63 Plymouth B body hunt resumed, off to eBay for a try there while I was restoring the Sport Fury Convertible. After much hunting, I stumbled across a Fury in Michigan with a very solid body but as I was later to find out was in horrible mechanical shape. So I bid on it and won. After a day long trip from Saint Louis to Ann Arbor and back, the project began.

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.
