Technical FAQ - Galfer Performance Motorcycle Braking Systems

FREQUENTLY ASKED QUESTIONS – FAQS

 

Can you make extended brake and clutch hoses for my bar/riser setup?

If you need to add length to our specifications for taller bars and risers, simply give our sales department a call. They can assist you in placing an order over the phone.

If you need to change fittings to accommodate a different master cylinder or calipers, please click HERE to start building your own custom lines.

Customized lines are built to order in 2-3 business days (plus shipping time from our Southern, CA facility).

Why go to a bigger diameter disc?

Bigger is better, right? Not necessarily. A bigger diameter disc does provide more power and better cooling (because any particular point on the disc spends more time in the cool air dissipating heat buildup) you do end up with less modulation (brake control).

Traditionally, downhillers, free riders, and tandem riders can all benefit from larger diameter discs. However, riders who spend more time in technical situations need to be aware that the larger diameter disc (like a lower bottom bracket) has a better chance of being struck and damaged by a boulder, tree stump or similar object.

Take a look at motorcycles and the diameter of their brakes. Most motorcycles run a larger (or dual) front brake rotor setup.

Materials

Galfer uses only 420 or 410 stainless steel for all of our brake rotors and it’s all about the memory!

What do we mean by that? Metals have memory which means that when you heat up a piece of metal and it expands. Good memory characteristics allow it to go back to its original shape without much deformation from the original shape.

It’s as simple as this: It goes back to its original shape and specs faster.

Laser cut vs. stamping

Stamping is great when you are doing mass production of tens of thousands of rotors. This is because the stamp itself is VERY expensive to make, but after the initial expense, it can quickly produce rotors that are relatively good quality.

On the other hand, laser cutting requires minimal initial expense other than a few hours programming time to make sure the laser follows the desired pattern. This allows you to easily and cheaply change the design after testing if the need arises. Because the programming time is all that is required for a completely new prototype, Galfer has the ability to do small batches of custom rotors to meet the needs of our clients.

Galfer can do an infinite number of combinations of diameter, bolt fixing pattern and Wave® pattern. We can even cut your company logo or name into a rotor design.

Laser cutting provides the most consistent cut quality and leaves the rotor substantially flatter than stamping.

Why the Wave® pattern?

Admit it! You’re interested in Galfer Wave®s because they look cool!

We like the way they look as well but believe it or not, there is quite a bit of thought that went into our patented technology.

On a normal round rotor, the leading edge (think toe-in) of the brake pad is in contact with the entire height of the blade as the pressure is applied. Because the contact covers the entire height of the blade, heat buildup takes much less time to occur and you end up with heat-related problems like brake fade, thermal lockup, and inconsistent braking performance.

What the Wave® pattern does is take that leading edge of contact between the blade and pad and constantly move it up and down, thus minimizing heat build up and its inherent problems. Cool air is also introduced in greater amounts.

In addition, through centrifugal force, any foreign matter is thrown clear of the outer rim of the blade and doesn’t get lodged in the pad material.

Do holes in discs help?

Well, it depends what you mean by “help”.

Holes in the “blade” of a disc (the part that the brake pad sweeps over as it is in motion) will save a bit of weight but contrary to public opinion, they do not help to cool a braking system. Notice on Moto GP motorcycles and most race cars, there are no holes on the rotors.

There are actually situations where holes can be detrimental to your braking. In muddy conditions, dirt gets trapped in these holes and proceeds to chew up pads that, in turn, will chew up rotors because of the constant uneven abrasion between the pads (which have the dirt imbedded in their surface) and the rotors, which get gouged to heck by that dirt.

If you’ll notice, if there are holes in a Galfer rotor, they are never round. They are usually oval, teardrop or cylindrical in shape so that foreign debris is directed away from the rotor via centrifugal force.

Stainless Steel vs. Nylon or Rubber line

If there is one item you can get that will make an instant, noticeable improvement to your brake feel and performance, switching to a stainless steel braided line is it!

When you squeeze your brake lever and force fluid through the hydraulic line to the caliper, the line expands under pressure. This means that a good portion of the effort you put forth from your hand DOESN’T get to the caliper! It makes the line expand.

By switching to a stainless steel braided brake line, you restrict the lines expansion characteristics. This means that your hand pressure goes directly to the caliper.

Does Galfer make brake calipers and levers?

Not for bicycles.

In the past, Galfer has made billet aluminum calipers for a few motorcycle observed trials applications but that is about it. Galfer products are specifically designed to make your current braking system better, regardless of their manufacturer.

Who does the testing on Galfer products?

We do!

At Galfer we like to joke that we are world-class riders, but we know what the truth is! We’re slow compared to some of our sponsored athletes.

That’s why we sponsor some of the finest riders on earth before releasing our brake products to the general public. Teams like Maxxis Racing and Santana Tandems for our bicycle products, Yoshimura Suzuki superbike team for our road motorcycle products, and AGP racing for motocross, and World Trials champion Dougie Lampkines thrash our stuff on a regular basis.

And we feel that if those guys love our stuff, then you will too!

Why do your front sportbike line kits not follow the stock routing?

Almost all of our front line kits are 2 line systems that have both lines exiting from the master cylinder and then going down to their respective calipers.

We have found that this type of routing allows for shorter lines, which allows for a firmer brake feel. Read more brake line installation information.

Can your banjos be rotated?

All Galfer fittings are what we refer to as Turn-to-Fit and can be rotated 360 degrees if required.

To prevent unnecessary movement at the connection point, determine how far the banjo will need to be rotated ahead of time. Next, identify the silver crimp collar on your line. It is the portion just below the banjo that holds the flex line in place. You will need to LIGHTLY hold this collar while rotating the banjo to prevent the line from twisting. Use a pair of vice grips on the LOWEST possible setting that will hold the collar. With the vice grips in place, insert a wood dowel, brass punch, or even a pen into the banjo and rotate it to the desired position.

If the line is already installed on the bike and you need to relieve tension or re-position it, you can simply hold the collar and rotate it slightly. Just be careful to rotate and NOT pry on the fitting.

If you have any questions or concerns, please contact our tech department before attempting at 1-800-685-6633.

What is the difference between your line kits?

All of our line kits are application specific, meaning not all of our brake line options are available for every bike.

For a list of what brake line kits are available, take a look at our brake line section. To help determine what kit may be best suited for your bike and riding style, check out our brake line kit video below or give us a call 1-800-685-6633.

Once you’ve purchased your brake lines, be sure to read our brake line install tips.
