DURABILITY & SAFETY by FERODO®PROVEN ONCE AGAIN
Whether you run a fleet of commercial vehicles or just repair them, one of your biggest concerns is keeping them on the road, running smoothly without accidents or unnecessary downtime. Brake quality and brake performance are key in achieving this.
COMPRESSIBILITY
STABLE FRICTION COMPRESSIBILITY IS THE MOST VALID MEASURE OF BRAKE PAD QUALITY
The compressibility of a brake pad's friction material should be within certain limits. It should be hard enough to ensure good pedal feel, minimal wear and sufficient power transfer from the pads to the disc. And at the same time it should be elastic enough to ensure sufficient grip on different disc surfaces. This makes it arguably the most important indicator of manufacturing process quality.
- the quality of the raw material ingredients in the friction material mix
- the way the friction material has been mixed
- the quality and consistency of the pressing process
- blistering during the press-curing process
- cracks in the friction material
- the bonding process between friction material and back plate
A DIRECT CORRELATION TO MAINTENANCE REQUIREMENTS AND POTENTIAL ON-ROAD ACCIDENTS
A high variation in brake friction compressibility can cause excessive brake wear. It can also decrease brake performance and consistency. Each of these issues can drastically shorten service intervals, and performance/consistency issues might even pose a threat to the driver's safety.
FERODO® PADS HAVE SOME OF THE LOWEST COMPRESSIBILITY VARIATIONS YOU WILL FIND
We compared the compressibility of Ferodo®pads to that of competitor pads, measuring the compressibility in multiple areas of the friction material. The table shows the range between the minimum and maximum compressibility values.
The results prove that Ferodo®offers some of the lowest – and therefore some of the best – variability factors on the market. We beat the competition at both 5MPa and 8MPa. This higher quality prevents the friction material from shearing off the back plate while driving. What's more, it ensures longer brake pad life with lower maintenance costs – which equals increased vehicle uptime.

HEAVY METALS
FERODO®IS CONCERNED ABOUT YOUR HEALTH AND OUR ENVIRONMENT
At Ferodo®, we understand that heavy and toxic metals have a major impact on workshop and installer safety – not to mention they seriously pollute the environment. Many of the competitor pads currently in the market still contain dangerous metals in their friction materials. The table below shows the ecological rankings for non-exhaust emissions provided by the EU in its Protocol for Heavy Metals.
Grade | Friction Material is free from the following: | |
Grade 1 | ECO-1 | Free of lead (<1000ppm) / Cadmium ≤ 2ppm |
Grade 2 | ECO-2 | As grade 1, & free of Antimony and its compounds |
Grade 3 | ECO-3 | As grade 2, & free of Toxicological fibres |
Grade 3E | ECO-3E | As grade 2, & free of Toxicological critical fibres (aramid fibres permissible) |
Grade 4 | ECO-4 | As grade 3, & free of Copper, copper alloys and copper compounds |
Grade 4E | ECO-4E | As grade 3, & free of Copper, copper alloys and copper compounds (<1000ppm) |
Ferodo®puts your safety first. We are one of the very first brake product manufacturers to exclude any dangerous metals such as antimony and lead, and have achieved a grading of ECO-3E. We use only safe raw materials that are of a higher quality and ensure improved compressibility and low wear.
