BENDIX R&D PROVIDES STRONG BENEFITS FOR THE AFTERMARKET
While brake pads appear to be simple components, they play a critical role in the braking system and have a complex manufacturing process
Research and development within leading brake manufacturer, Bendix, plays a vital role in the development of advanced braking solutions for the aftermarket.
Brake pads are manufactured using a combination of ingredients; these include Fibres, Functional Fillers, Friction Modifiers, and Resin Binders. Different driving styles and vehicles require different formulations of each ingredient in order to provide full confidence when braking.
There are three main types of friction material used for the manufacture of brake pads. They are Non-Asbestos Organic (NAO), Semi Metallic (Semi-Met), and Low Metallic (Low-Met), and each material is suited to different applications.
Bendix NAO brake pads
NAO formulations, also known as ceramic materials, are used in Bendix General CT and 4WD/SUV brake pads. Ceramic brake pads have low levels of noise, dust, and rotor wear, while providing a consistent pedal feel.
They use a combination of synthetic glass fibres, aramid fibres and natural organic fibres as the main reinforcing ingredients. Braking performance for each car make and model is further fine-tuned by adding organic or inorganic modifiers.
The manufacturing process of Bendix NAO brake pads is complex, with production methods dramatically increasing the lifespan and durability of NAO brake pads. The ingredients are carefully picked to fine tune braking performance for each individual car model.
When braking, a Bendix NAO brake pad applies a coating to the rotor called a transfer film. The pad uses this film for 90 percent of everyday braking work, to protect the brake disc from wear. The transfer film constantly gets worn away and built up again through general, everyday city or country driving.
Bendix General CT brake pads are highly suited to small to medium sized cars that do daily driver duties. For heavier 4x4s, all wheel drives and SUVs, the Bendix 4WD/SUV brake pads provide the required performance for extreme conditions and on road feel.
For performance cars that are driven hard or, for vehicles that tend to tow on a regular basis, brake pads with higher metallic content is needed. This is where Ultimate and Bendix Heavy Duty range of brake pads come in.
Bendix Low Metalic Brake Pads
Non-asbestos organic (NAO) brake pads are suitable for a wide range of driving styles, with low dust, consistent brake performance at relatively low temperatures and speeds.
However, when cars regularly travel at higher speeds or require greater performance, brake temperatures rise, and this can cause brake fade, reducing stopping performance.
In these situations, brake pads with Low Metallic compounds excel, says Bendix.
Low Metallic (Low-Met) brake pads are suited to performance and high speed driving styles and contain high levels of mineral abrasives to provide better stopping power.
The Bendix Ultimate and Street Road and Track contains these ingredients to provide exceptional stopping power and shorter stopping distances. It is also more resistant to brake fade at high temperatures, delivering consistent brake pedal feel after a hot lap performance drive.
Bendix Ultimate and Street Road and Track pads are recommended for high performance vehicles that do spirited driving or track racing, where braking performance is paramount.
Bendix Ultimate brake pads feature HPC technology that reduces brake dust, without compromising stopping performance. Bendix Ultimate and Street Road and Track brake pads also come with Bendix’s proprietary brake shims, featuring a nitrile rubber coating that absorbs noise and vibration under braking.
Bendix Semi-Metallic Brake Pads
Hardworking vehicles such as utes, trucks, vans or cars that do frequent towing, require a brake pad that can resist brake fade, lasts extra-long and still remain quiet in operation.
Semi-metallic brake pads such as the Bendix Heavy Duty range are highly suited to these vehicles. Containing relatively large amounts of steel and iron, the brake pads are specially designed to be fibrous. This allows gasses that formed during the manufacturing process to be released, increasing the structural integrity of the brake pad.
The Bendix Heavy Duty brake pad formula has an Insulayer to increase endurance and braking performance, without lowering brake rotor life. They also generate less brake dust, and the Bendix’ proprietary brake shims with rubber coating reduces noise from the brake pads.
By increasing brake pad and rotor life, running costs for commercial vehicles are lowered by saving in servicing costs and reducing time off the road.
Bendix Brake Pad Range Explained
Different people use their vehicles differently, and that’s why Bendix has a range of brake pads to suit differing driving needs. Whether it’s everyday general driving, off-roading, towing or even the odd track day, Bendix has just the right brake pad to suit it says.
The General CT is the Bendix’s brake pad for everyday driving. Designed to eliminate brake dust and noise, the General CT brake pads suit the commuter who needs quieter, cleaner and more consistent performance for everyday driving.
Patented STEALTH Advanced Technology reduces noise and vibration by using diamond-shaped pads. Bendix General CT also features a Blue Titanium Stripe for instant friction without the need for bedding in.
Available for over 95 percent of cars on the road today, the General CT promises dust-free, quiet and reliable braking performance.
The new Bendix Heavy Duty pads are designed for every ute, van and pick-up on the road. Manufactured using a specifically developed compound, the Heavy Duty delivers real performance for all sorts of load carrying situations. Whether it’s the stop-start city driving, frequent towing or the hard grind of construction sites, the Heavy Duty will handle any situation that involves heavy loads.
The Bendix Heavy Duty brake pads come with an exclusive insulation layer between the friction material and backing plate for cooler braking and longer rotor life. The Bendix Blue Titanium Stripe means that no bedding in is required for the Heavy Duty brake pads.
For keen off-roaders, the 4WD/SUV brake pads get the job done, whether they go around the block or across Australia. Manufactured for extreme strength, extended life, and great pedal feel, it can be relied on for heavy braking, city driving, towing or bush beating.
The Bendix 4WD/SUV brake pad features a unique groove to expel any water, dirt, or dust that comes into contact with the pads, inevitable when off-road driving. The patented Bendix Blue Titanium Stripe means no bedding in is required, and the brake pads are ready to work straight away.
Designed specifically for the complex braking systems found in most European cars, the Bendix Euro+ features better braking performance than original equipment brake pads, without the brake dust.
Each Bendix Euro+ application surpasses stringent OE quality requirements from premium car makers such as Mercedes Benz, BMW, Volkswagen and Audi, to name a few. All Euro+ brake pads come with required parts such as clips, shims, or sensors for easy installation.
The choice of friction material will impact on your braking experience which is why it’s important to match your driving needs and vehicle with the right brake pad formulation.
Bendix Ceramasil Brake Parts Lubricant
When two objects move relative to one another, the molecular interaction between the two surfaces leads to wear.
In a brake caliper, the pads move in their abutment slides not only when the brakes are applied but also when vibrations are transmitted from the road surface and drivetrain.
Some of the mechanisms of wear are closely related to corrosion when oxygen from the air reacts with metal to form oxides which can act as an abrasive. Bendix has identified that a key to avoiding the accelerated wear process is to avoid the formation of metal oxides by excluding oxygen-rich air from the surfaces with a specially formulated lubricant.
Applying the Bendix Ceramasil Brake Parts Lubricant between the back plate of the pad and the piston and fingers of the caliper is an effective way to overcome this problem and is also an effective way to isolate the pads and decouple a system resonance.
Whilst any grease will do the job temporarily, the Bendix lubricant has been created specifically to protect and lubricate brake systems. It will last the life of the brake job, silencing calipers, resisting pressure cleaning and extreme conditions and providing against friction wear and corrosion.
Bendix engineers in research and development draw on original equipment experience and play an important part in bringing leading edge products to the aftermarket.
