One of the most striking features of the Bendix General CT, 4WD and Heavy Duty brake pad ranges is the Titanium Stripe. It’s not there to look good, but to do away with the time consuming process of bedding in. This unique stripe provides instant friction to deliver positive pedal feel and sure stopping power from the moment your customers drive out of your workshop.
HOW DOES IT SAVE YOU TIME & MONEY?
For every brake job you do, you can save 10 minutes of bedding in time, as the normal bedding-in procedure is a minimum of 30 stops. Three brake jobs a day means 30 minutes a day or at least 2 1/2 hours a week. That’s more time to spend on other jobs and more money in your pocket.
THE SECRET BEHIND THE SCIENCE.
Because of the high friction characteristics of the Titanium Stripe, contact between the pad and rotor surface is accelerated. The actual bedding-in process takes place under normal driving conditions as the Titanium Stripe achieves full contact between the pad and the rotor. The illustration shows a typical brake pad set in position next to the rotor. If we were to place the circled area under a microscope, you would see that both the pad and rotor surfaces are rough.
When brakes are applied, the pad and rotor surfaces come into contact. Due to the surface roughness, the contact area on regular brake pads is very small with only extremities touching each other. However on pads with Titanium Stripe, the key properties of the titanium coating material are its high friction level, and its rapid interaction rate. When the brakes are first applied, the titanium moulds very quickly around the points of contact, rapidly increasing contact area as the titanium mates to fit the rotor surface as shown below.
The entire braking load of the car is carried by these point contact areas, causing them to heat up very quickly. The high temperatures, combined with the high contact pressure, cause poor braking performance. There is a serious risk of overheating the brakes, even in normal driving conditions. After about 50 stops, the pad surface wears to fit the rotor surface and the contact area increases. This spreads the braking load over a wider area, resulting in lower point temperatures.
However, it’s a very different and improved process with the Titanium Stripe. The titanium layer quickly adapts to mate with the rotor, achieving full contact between the surfaces of the pad and rotor after only a few stops. This avoids localised overheating, as the braking load is spread across the entire surface of the pad. When the titanium wears through, the parent friction material starts adapting to fit the rotor surface, while the remaining titanium maintains full contact.
Complete bedding-in can take 200 normal brake applications. Stopping once every kilometre, that’s 200km driving before the brakes achieve full surface contact and peak performance. The first 30 stops are critical, which is why mechanics are advised to perform a minimum 30 stop bed-in drive before returning the car to their customer. With Bendix pads coated with a Titanium stripe, full braking performance is achieved after just a couple of stops. After 50 stops, most of the titanium is worn away and the parent material is in the process of bedding-in to the rotor.
IMPORTANT: Titanium Stripe is NOT a substitute for machining rotors. The Titanium Stripe does not machine the rotors, and is not intended to be a substitute for good workshop practice.
The Titanium Stripe is another exclusive innovative technological advancement from Bendix.
