Wet Brake Performance

R90 TESTS ARE ONLY CONDUCTED ON DRY CONDITIONS

European legislation stipulates that all brake pads sold for use on vehicles must be tested, and comply to R90 standards. The R90 test includes cold and hot brake friction analysis and if a brake pad has been R90 approved, it can be safely assumed that the product is within 15% of the original equipment product performance.

Because the R90 test is only conducted in dry braking conditions we decided to benchmark Ferodo brake pads against some competitor pads in wet braking conditions. Between the tested materials it’s easy to see that Ferodo offers brake pads with the lowest reduction of friction level in wet conditions.

THE WET BRAKING PERFORMANCE TEST

This test compares the reduction of friction performance in wet braking conditions between Ferodo pads and competitor pads was conducted on a Ford C-Max. Six brake applications in dry conditions were measured, after which the brakes were sprayed in water for another six wet brake applications. To be sure that all the tests are conducted with equivalent and consistent brake pads, all brakes were bedded in first using identical procedures on new discs.

The graph above shows you the percentage of friction level reduction – or brake performance – between braking in dry and wet conditions, with Ferodo showing the lowest reduction from dry to wet compared to some competitors.

THE RESULTS

As the chart shows, Ferodo brake pads have the most consistent reduction of brake performance under wet braking conditions when compared to the competition. Previously conducted tests have already shown that Ferodo provides short stopping distances, low brake noise and great pedal feel. We can now proudly add that we have some of the best wet braking performance - proving again that with Ferodo you’re in control.

TEST PARAMETERS

• Brakes fully bedded-in through a cycle of 60 brake applications.
• Dry coefficient of friction is determined by taking the average of 6 brake applications from 50 to 19 mph (80 to 30 km/h).
• Wet conditioning is achieved by spraying the brake system for 10 minutes with water at a speed of 19 mph (30 km/h).
• Wet coefficient of friction is determined by taking the average of 6 brake applications from 50 to 19 mph (80 to 30 km/h).
• Vehicle: Ford C-Max, at a gross vehicle weight (GVW) of 2 Tons (1990 kg).
