Frequently asked questions...

Does the Traction Controlled Braking Unit Allow Air into the Brake System?

The Traction Controlled Braking System DOES NOT Allow Air to seep into Your Braking System. The air is totally sealed in the upper compartment of the traction control unit. Having the air sealed in the upper unit by a rubber diaphram, the unit introduces flexibility into the system. Imagine your car without shock absorbers. With a shock absorber it allows flexibility, just like the sealed top part of the TCB does with it's pocket of air. This product has been tested by both Lockhart Phillips and Zodiac, both which immediatly placed orders for more.

By "high and low spots" on the rotor are you referring to a warped rotor?

No. Rotors have natural peaks and valleys. Run your hands across your rotors and you will feel them.

Does the TCB Device meet all DOT and NHTSA certifications?

Yes. TCB Brake Systems are considered an aftermarket item. Self certifications and private hydraulic pressure tests for product integrity and quality control are sufficient. As stated by the Office of Vehicle Safety, "presently there are no required certifications needed for mechanical aftermarket brake products other than brake hoses" ( The TCB unit will actually be one of the strongest parts of your braking system having been tested at over 4500 psi.

Will installing a TCB Brake System void my vehicle warranty?

No, the TCB Braking System does not void your current vehicle warranty. Federal law prohibits manufacturers from voiding warranties based on the addition of aftermarket parts, unless they can prove that the aftermarket item caused a failure in the vehicle.

How does Traction Control Brakes work?

Traction Control Brakes add an extra give/compressibility factor (like a shock absorber) inside the brake line of your brake system. The TCB allows the brake pads to float and drag over the high and low spots of the brake rotor which helps avoid premature lock-up of your brakes.

The TCB just looks like a bolt; what makes it work?

There is a small rubber diaphragm that separates a chamber of air from the brake fluid which creates a "shock absorber" like affect to help reduce your wheels from premature locking.

What is the difference between ABS and Traction Control Brakes?

Anti Lock Brakes (ABS) are electronic systems that measures the wheels speed and registers when the wheel has stopped rotating. The computer then allows the brakes to lock and unlock numerous times per second to help prevent the wheels from locking up. Antilock brakes and Traction Control Brakes both rely on the coefficients of friction to allow the wheels to rotate for additional control. It needs to be emphasized that ABS still lets your wheels lock, ABS only works at particular speeds and after the wheels has experienced total lock up. Traction Control Brakes are an all mechanical system that works every time you brake by helping you modulate your brakes for optimum performance and a feel of total control in your braking.

Can the TCB Unit Fail?

The TCB Unit has only one moving part, the diaphragm inside the unit, which helps to modulate the brakes. The manufacturer of the Traction Control Brake Unit uses the best existing polymers to ensure resilience to the brake fluid and the heat that comes from the brakes. Although the manufacturing process ensures that the unit will not fail, if the diaphragm does fail, your brakes will still work the same way they did before the unit was installed. TCB units are designed to withstand more than 4500 psi before rupture which makes it one of the strongest parts in your braking system. If a rupture should occur the TCB has a secondary seal that prevents any leaks or total loss of brake pressure well beyond 4500 psi.

Isn’t it dangerous to change something in the brake system?

No, replacing your banjo bolt with a TCB unit has no more risks associated with it than you would have if you were changing out your banjo bolt with another banjo bolt or changing any other component in your brake system. Always Remember that you need to bleed your brakes properly and follow your manufacturers’ instructions.

What type of testing has been done?

TCB Units are repeatedly tested for durability during the manufacturing process. Because the weights of motor sport vehicles are different and because surface conditions are not the same, it would be nearly impossible to test every make and model of motor sports vehicles. Because the TCB unit is designed to withstand over 4500 psi before the internal diaphragm ruptures it is actually one of the strongest parts in your brake system. If for some reason the diaphragm did rupture there is a second seal so the TCB unit prevents any leaks or pressure loss even over 4500 psi.

Do the units wear out?

Each TCB unit is designed to last as long as your vehicle. We will replace any defective units for the life of your vehicle.

What happens if I only have a TCB on the front caliper?

Because 70% of the weight transfers to the front brakes during breaking, the TCB Unit on the front is the most important. The front caliper is where the TCB Unit gives you the biggest change in how your brakes work.

What if I only have a TCB unit on my back caliper?

Since the rear brakes have much less total weight on them during braking you will find the Traction Control response when the unit is installed on the back caliper is not as large as it would be on the front. So to get the feeling that our customers have described as "total controlled braking" you should get a TCB unit for the front first.

What benefits will I see with the unit on the front?

With a TCB on the front you will find that there is less premature locking of the wheels, and you will have an increased ability to control your vehicle during aggressive braking giving you the feeling of total controlled braking.

What benefits will I see with the unit on the back?

Having a TCB unit on the rear wheel will allow better "tracking" during aggressive braking maneuvers and cornering, but to get the full feeling of total control in your brakes you should put one on your front brakes first. Having a TCB unit on either the front or the back brake produces the same function, but, because of the weight transfer to the front of the vehicle during braking, you will feel the most change with the unit in the front.

What benefit do you get by having a TCB Unit on both the front and back?

You get the total control a rider can experience during braking by having a TCB unit on both the front and rear wheels.

Is their a difference in braking performance if the TCB unit is installed at the caliper or master cylinder?

No, the unit can be installed at the master cylinder or the brake caliper and the effect will be the same.

Will there be a change in the feel of my brake controls?

You will feel a difference, the first time you ride with a TCB unit installed, in the brake lever or the pedal. Although it will seem to be softer, the reaction of the brakes becomes more responsive. This is part of the increased feeling of the total range we describe, so there is more difference in the feeling between lightly braking and totally locking your wheels. There is no cause for alarm, what you feel is the TCB unit working and the TCB unit works every time you apply the brakes at any speed.

Do you recommend putting a TCB on an ABS system?

No, we do not recommend this.
