Correct Friction Material Comparisons-Silverback’s comparisons to Meritor “MA” OEM production friction materials are false.-Silverback friction is Chinese-made aftermarket-only, not used in North American OEM brake production.

The following brake lining and brake drum wear comparisons were provided by Fras-Le North America based on the following test criteria.- Wear vs. Temperature test TP212A- Meritor 16.5” x 7” Q Plus brakes- Meritor cast drum- AL factor 165- 20K Axle load- Wear testing is conducted at 250, 350, 450, 550 and 650 degrees F,

from 40mph to 20mph constant decel rate of 3 ft/s2. - Data points are the average of 1,000 brake snubs at each

temperature.

Meritor MG vs Silverback Friction Evaluation

Overall, Silverback friction wears twice as fast as Meritor MG comparable mixes

Silverback wear gets noticeably worse at higher temps.-Between 550 and 650 degrees, Silverback SB23 causes almost 1.25 pounds of drum loss (310 plus 246 grams).

SB23 lining wear looks good with only 4cc’s loss at 250 degrees, however it also causes 81 grams of drum loss at 250 degrees. That may indicate swelling of the block that could be causing other brake issues such as drag.

IMPORTANT!

Fleets will DOUBLE their number of relines using Silverback!

Ceramic fibers are used for producing fireproof fabrics and building materials because of a higher level of heat insulation v other man-made fibers.Ceramic fibers are also used in premium automotive brake disc pads, especially for racing, where extreme brake temperatures are reached.However, as indicated by the wear comparisons, ceramic fibers add nothing to Silverback’s performance, especially at the higher temperatures.Most commercial brake block utilizes a form of chopped fiberglass.- Chopped fiberglass is a U.S.A. safety requirement because the

fibers are small and can be breathed out or absorbed by the body.- If man-made fibers are too long, they can be trapped in the lungs

and cause health problems.Do the ceramic fibers used in Chinese brake block meet U.S. safety requirements? Does Silverback provide MSDS safety sheets?

IMPORTANT! Ceramic fibers do not offer an improvement vs. other man-made fibers &

may be a safety hazard.

Meritor MG Aftermarket Friction Man-made fiber is only one ingredient in a friction material formulation. Other ingredients include:- Friction “modifiers” (rubber, metals, nut shells, denim, etc.). Modifiers

effect co-efficient of friction and wear.- Resins. Resins are the “glue” that holds the dry brake block

ingredients together. Resins are available in various formulations to withstand a variety of temperature levels.

- Resins, more than any ingredient, determine the heat-resistance of brake block.

Fibers, in brake block, act as the binder to hold the other ingredients together with the resin.

Friction material formulations are designed to meet the specific performance and life needs for the variety of commercial vehicle applications.

Meritor MG Friction

Meritor MG uses market-proven quality ingredients to achieve the highest level of vehicle braking performance and life.

Meritor MG has produced commercial vehicle friction materials, for the North American market, for almost 30 years.

Meritor, Inc. is the largest worldwide manufacturer of commercial vehicle braking systems.

Meritor is the exclusive distributor of Meritor MG aftemarket friction in North America.

IMPORTANT!Friction materials produced and supplied by the market leaders in

commercial vehicle braking or from an unknown, unproven source. Which product do you want to rely on to stop your

80,000lb. vehicle?
