All components are precisely matched to each other and individually designed for each vehicle model.
Brake pads
Made from high-quality ingredients for excellent noise and vibration behavior.
Brake caliper
Converts the hydraulic pressure for an excellent braking effect.
Piston for power transmission
For even pressure distribution.
Brake fluid
High dry and wet boiling point with low viscosity for a fast reaction time.
Brake disc
Minimal manufacturing tolerances and homogeneous cast structure for smooth running and heat resistance.
For low noise development
Friction material
Individually selected for each vehicle, they ensure short braking distances and a high level of comfort.
Intermediate layer
Influences compressibility and reduces noise.
Adhesive
Secures the connection between the lining carrier and the friction material (shear resistance).
Pad carrier
Ensures reliable power transmission; coated with high-grade varnishes to prevent corrosion.
Anti-vibration material
Insulating coating made of rubber, plastic or metal (shim) to improve noise and comfort properties.
Tests specified by EU standard ECE R90:
Additional tests at Bosch:
In so-called dynamometers, ambient temperatures of -40 to +60 degrees Celsius are simulated and brake performance tests are carried out for light commercial vehicles up to 7.5 tons or sports cars with a top speed of 320 kilometers per hour.
Secret recipe for brake pad mixture
Up to 20 different raw material components are processed into a homogeneous brake pad compound. The exact composition of the brake pad compound is decisive for the quality and performance of a brake pad.

ENV6 product range
For over two years, Bosch ENV6 was geared to new versions of ABS and ESP® in the Bosch test bench laboratory and subjected to high loads in tests that exceed the legal standard:
Total area of 94 hectares with a large number of different test tracks on a total area of 25 hectares. The site is surrounded by the three-kilometer high-speed oval. All other test tracks are located within the site.
The test season in Vaitoudden lasts from the end of November to the end of March every year. The winter test center offers test tracks, workshops and offices. It is located about 10 km northwest of Arjeplog on the Vaitoudden peninsula in Sweden.
Covering an area of 120 hectares, the Juvincourt proving ground offers a 4.2-kilometer circuit and 26 different test tracks, one of which is certified by the FFSA.
With compound brake discs, the vehicle-specific nominal torque is achieved in three steps during wheel assembly:
Wheel bolts crosswise
When mounting the brake caliper or changing the brake pads, the steering angle may only be adjusted via the steering wheel. Loads on the windshield must be avoided.
Moisture, road salt and dirt can cause brake fluid to leak, the pistons to no longer move properly and the brake pads to run uncleanly.
Therefore: service the braking system regularly, e.g. by cleaning the moving parts. If the function cannot be maintained in this way, the road safety of the vehicle is at risk. In this case, it is essential to replace the brake calipers.
Before fitting the brake discs, the contact surfaces of the wheel hub must be cleaned, rust-free, burr-free and flat and must not show any signs of damage.
Fit the brake pads correctly to avoid brake noise:
Reasons for vibrations and noise:
The BFT 100 is the ideal tool for measuring the boiling point of brake fluid:
Installed in just 30 seconds and easy to use thanks to direct connection to the vehicle battery – no need to charge the device before use.
Please note: If brake fluid drips onto the paintwork, rinse off with plenty of water.

As an important partner in the automotive industry, Bosch has repeatedly developed innovations to improve driving safety. Numerous inventions from Bosch set the technical standard for braking systems today, e.g. the anti-lock braking system (ABS) and electronic stability control (ESP).
One of the latest innovations is the brake-by-wire system: it completely replaces the mechanical connection between the brake pedal and the braking system with electrical signal lines.
