The laboratory specialized in brakes together with the research and developmental centre continuously control manufactured products at each stage of their production. Due to it, the highest quality requirements established by extremely diverse selling markets of cold and wet Scandinavia as well as hot and dry Africa, are observed.

The effect of work of TOMEX engineers as well as hundreds of works on experimental trucks is the new friction material which meets the highest legal requirements in the whole EU and ensures comfort of braking in all road conditions.

ECE R-90 regulations as the part of 98/12/EC directive referring to brake devices, which is binding as of January 1^st, 1999 and is applied as mandatory since April 2001 guarantees that the parameters of friction lining for disc and drum brakes may diverge from the original ones on the level of the maximum +/- 15%. At the same time, the fact that TOMEX company observed all the requirements of ECE-R90 regulations guarantees the highest quality.

THE EFFICIENCY OF BRAKES

The chart shows the characteristics of the efficiency of front wheel brakes with TOMEX friction lining compared with the lining of original equipment.

Trying to face up further challenges, TOMEX laboratory has prepared a mixture in which the share of heavy metals was reduced to the minimum and all formulas of applied friction materials are exactly adjusted to the specificity of the given vehicles, due to which they ensure the highest level of braking control, long shelf-life, quiet operation and minimization of excessive and aggressive contamination of wheel rims.

TOMEX pads also undergo difficult tests such as high load test and Alpine test during which on the road with the slope of up to 20% a 12-minute uninterrupted braking takes place and the temperature of pads in the conditions reaches even 850 Celsius degrees. It aims at ensuring the maximum safety level and the performance of TOMEX brake pads similar to the original equipment. Except for incredibly strict laboratory tests, for each reference introduced, a series or road tests in special research centres in Poland as well as in RDW Test Centrum Lelystad in the Netherlands are carried out.

FADING

One of the key steps in AK-Master test is the assessment of the dependency of the friction coefficient from temperature. The chart below presents the comparison of TOMEX company material with OE material during the brake fade that is the measurement of the influence of increasing temperature on the braking efficiency.

Each month, the Laboratory performs over 100 various tests of not only finished products but also of the given components in order to guarantee the highest quality of the final product.

Temperature is the indispensable element of the braking process in every vehicle. In the tests we heat up the disc to the temperature of the red heat, which is much higher than 1000 Celsius degrees.

The introduction of the new reference for sale is preceded with hundreds of hours not only in the Laboratory but also at experimental trucks in Poland, Germany and Great Britain.
