High Density Low-metallic Formula CV Brake Pads

Choosing the right friction solution needn’t be a challenge. Bull Brakes CV Brake Pads Series continue to provide exceptional reliability and quality performance vital to commercial vehicles. Merging with Bull Brakes‘ the most leading Friction Hybrid Compounding Technology, the CV brake Pads have a strong, predictable friction level regardless of temperature, speed or axle load. Designing for harsh conditions and is validated to OE specification, for low wear and long life, particularly at high temperatures.


Friction Hybrid Compounding Technology

Merging with Bull Brakes’ the most leading Friction Hybrid Compounding Technology to creat new friction fomulation. Each intergated formula are formulated at a moleculare level to determine the formula structure.

Postive Molding Technology

Using the most advanced one-step molding process to suppress; Accurate weighing and feeding, applying with Bull Brakes’ the most leading Friction Hybrid Compounding Technology, each piece is just right.

Heat-conducting materials

CV Low-metallic HD formula uses a combination of metal fibers, which are heat-conducting and heat-dissipating, to facilitate heat dissipation during braking, Thus to cool the brake pads quickly without change the overal formula chamical property due to excessive temperature, thereby reducing brake fade from high temp.

Super Carbon-based Friction Performance Modifiers

Carbon-based(including chopped graphite paper and high-performance synthetic graphite) friction modifiers are added in proportion to make the brake pads more wear-resistant, less likely to fall off dust and less likely to produce noise.which not only ensures good thermal conductivity, but also increases wear resistance. At the same time, carbon fiber can also be used as a skeleton to firmly lock the dispersed powder and enhance the entire formula clustering.


1. Groove design is conducive to ventilation and heat dissipation, effectively reducing brake fade from high temp.

2. During braking, groove can also increase the drainage and sewage capacity, keep the brake pads and brake discs clean.

3. Friction dust can be discharged through the groove, thereby reducing the brake noise and mating parts damage, prolonging the service life of brake discs and brake pads.

4. Good groove is a warning line. Visually check is simple and safe.

OE Scorched Surface

1. The top layer of the friction surface is thermal treated at 650-800℃, to make it carbonized deep into 1.5mm, without interfering the inner of the friction materials and the backing plates.
2. Scorched surface is designed for instant friction, allowing to obtain brake effectiveness immediately.

Unique Brake-in Stripes

1. Brake-in stripes is a unique formulated rubber strip, it is a design for instant friction during the brake-in time.
2. Positive pedal feeling, straight out of the box without bedding-in.


CV Brake Pads are always exposed to extreme road conditions and loads. A secure bonding of the friction material to the backing plate is therefore imperative and important. Depending on the different application and road condition, UAI uses a range of different mechanical processes on its commercial vehicle brake pads to provide the suitable strength force power for each application demands:

URT(UAI Mechanical Retention Technology) Solution

One is UAI’s latest URT(UAI Mechanical Retention Technology) solution, the surface of friction side is full of hooks, with height over 1.5mm, Hooks will dig into the friction materials, deeply rooted, thus to improve the shear bonding strength greatly.

Full Mesh Welded Solution

The second is UAI’s full mesh welded solution, the surface of friction side is welded with a steel mesh with full coverage, with thickness of over 1.3mm. Mesh will be deeply rooted in friction materials to improve the shear bonding strength.

Casting Iron Solution

The third is UAI’s Casting Iron backing plates solution, The layout and height of pins on the surface of friction side are well designed, which will deeply root into the friction materials to provide the a best bonding strength. Casting Iron backing plate is with the lightest weight, which can meet the requirement of lighter vehicle components in more and more world market.

Advanced Glue Spraying Technology

Advanced glue spraying technology, combinding with one of the above solution, our CV brake pads can handle for all different road condition and thermal load requirements; Glue is evenly and effectively dispersed on the friction surface of the steel back, with the thickness of the glue from 0.1mm-0.2mm.


1. Using high-quality Q235B carbon steel, with high yield points at 235MPa, no possible to bend during the braking.

2. Thickness is uniform, flatness is controlled within 0.1-0.2mm;

3. Quality is stable and consistent.

4. Molds are manufactured according to the FMSI standard drawings;

5.Strictly produced, accurate size to match for the OE brake capilers and brake discs;

6. Perfectly fit in the caliper, thus reduce the noise caused by friction with the caliper accessories during braking.


1. Applying the most advanced electrostatic spraying process, suface of brake pads will be fully covered by the atomized powder coating, no area will be missed.

2. Atomized powder coating is evenly and effectively dispersed on backing plates,with the thickness of the powder coating up to 90μm.

3. Effectively prevent the steel back from contacting with oxygen, thereby oxidizing.

4. Extending the service life of brake pads.
