Program Overview:

• New Federal regulations, in place since August 2011, require Navistar and other Truck OEMs to build trucks that meet a shorter stopping distance. In most applications, this new shorter stopping distance is 250 ft.

Letter #: DYN-04-6558-A Posted Date: March 13, 2014 Effective Date: March 13, 2014 Expiration Date: December 31, 2014 APPLICABLE TO UNITED STATES DEALERS ONLY

Letter # DYN-04-6558-A 3/14/2014 Page 2 Technical Updates:

• Multiple changes to Navistar’s production brake system were made to meet these new stopping distances, including a larger front brake diameter, wider rear brake widths in some applications, and more robust front brake air systems. Meritor also developed a friction material specifically for reduced stopping distances (RSD), which is installed on International, IC, and other competitors’ vehicles with air brake systems.

Letter # DYN-04-6558-A 3/14/2014 Page 3

Stocking Recommendations:

• In order to maintain correct braking application, Navistar recommends that production RSD brake shoes are replaced only with Navistar approved RSD products. The correct Meritor reman brake shoe kits that match Navistar’s production friction are:

: • To ensure superior customer support, Navistar recommends stocking these 5 part

numbers to ensure International, IC, and other OE customers can easily maintain their trucks with RSD brake shoe kits.

• Please note, XK20014707QPMB is also available, but is not considered to be a financially beneficial product for the customer. Navistar recommends instead using XK20014707QP.

MERITOR® REDUCED STOPPING DISTANCE FRICTION MATERIALS

Re-engineered friction materials for better braking performance.

MERITOR REDUCED STOPPING DISTANCE FRICTION MATERIALS RSD FRICTION MATERIALS

Meritor friction materials offer a better idea to meet reduced stopping distance requirements with improved lining life.

REDUCED STOPPING DISTANCE FRICTION MATERIALS OFFER IMPROVED LINING LIFE

Meritor ideas bring unique solutions to the industry. Like our Reduced Stopping Distance (RSD) friction material. In addition to meeting the FMVSS 121 reduced stopping distance requirements, Meritor friction materials have been re-engineered to offer improved lining life compared to older-generation Meritor materials. That’s a better idea that delivers the braking results fleets and end users want.

The National Highway Traffic Safety Association (NHTSA) stopping distance regulation change went into effect for new tractors August 2011.

Important Facts about the Stopping Distance Regulation Change and Meritor RSD Friction

• The regulations affect new tractors only; existing vehicles are not affected

• Meritor RSD friction is available for fleets that want to standardize on friction materials

• Meritor RSD friction materials are available on new or reman shoes with PlatinumShield™ coating

For answers to commonly-asked questions on reduced stopping distance requirements, see publication SP-11137.

REDUCED STOPPING DISTANCE (RSD) REQUIREMENTS

FREQUENTLY ASKED QUESTIONS

How Does RSD Impact the Aftermarket?

The new reduced stopping distance requirements provide an opportunity to install not just new friction, but materials that deliver the braking results your customers want. Meritor has re-engineered its friction materials to meet the new reduced stopping distance requirements and beyond in some instances. Below are answers to commonly asked questions about the new regulations and the decision to standardize friction.

About the Stopping Requirements

Q. What are the new FMVSS 121 stopping distance requirements and when did they take effect?

A. The new FMVSS 121 stopping distance requirements are illustrated in this chart:

Compliance Date

Vehicle Configuration

Tractor GVWR (lbs.)

Loaded 60 MPH Stopping Distance (ft.)

Previous New

Phase 1 Aug 1, 2011 Three axles 0 to 59,600

355

Phase 2 Aug 1, 2013

Two axles All 250

Three axles59,600 to 70,000 250

Above 70,000 310

Four or more axles0 to 85,000 250

85,000 and above 310

Q. Do all new Meritor RSD friction materials meet the new stopping distance requirements?

A. Yes. All new Meritor RSD brakes will meet the new requirements with an additional 10% margin.

Q. What is the impact on my existing vehicles? Do I need to change my existing vehicles to the new Meritor RSD friction materials?

A. The law only affects new production vehicles. There is no requirement to retrofit older vehicles.

Important Facts About the Stopping Distance Regulation Change and Meritor RSD Friction

n The regulations affect new tractors only; existing vehicles are not affected

n Meritor RSD friction is available for fleets that want to standardize on friction materials

n Meritor RSD friction materials are available on new or reman shoes with PlatinumShield™ II coating

Q. How is compatibility between tractors with the new Meritor RSD friction materials and trailers with older brakes and friction materials affected?

A. Tractor-trailer brake compatibility was a design requirement for new Meritor RSD friction materials. Our solutions have been developed to maintain tractor-trailer compatibility with existing trailer fleets. The tractor will incur approximately 5% more of the braking workload, while the trailer will experience a proportionate reduction in workload.

Q. Regarding the new Meritor RSD Q Plus brakes, what has changed other than the friction material?

A. Since front brakes now absorb more brake torque, the front brake spiders have been made heavier and the mounting bolts are a larger diameter. Front brakes now use Type 24 brake chambers, increasing the AL factor to 132.

Q. Are larger brake sizes required to meet the new Meritor RSD requirements?

A. Not in all cases. Meritor has worked with all of the major vehicle OEMs to design the brake package to meet the new stopping distance requirements. Brakes may be slightly different from OEM to OEM. A 15” front brake package is still available, however most new front brakes are 16.5” diameter. See the Meritor application charts for specific sizes per OEM.

Q. Are there advantages to using larger brake sizes for the Meritor RSD requirements?

A. Larger brakes will provide some advantages, including increased lining volume to drive longer service intervals, lower operating temperatures, reduced fade and improved performance.

Q. Will my service practices have to change?

A. No, service practices do not change. Service technicians and mechanics will not have to be re-trained and parts inventory practices will transition to the brakes. However, new parts will need to be stocked including new brake shoe FMSIs, hardware kits corresponding to the new brake sizes and air disc brake components.

Q. Can a fleet retrofit all of their drum brakes to the new Meritor RSD friction materials?

A. Rear brakes can be retrofitted from existing materials to new Meritor RSD with no problem. Meritor RSD friction materials may increase torque in older front brake designs and affect the integrity of older front spiders with 5/8” bolts. However, the effect of Meritor RSD on older front brakes has not been determined.

Q. Will the use of Meritor RSD friction materials on vehicles with older brakes improve the stopping distance of those vehicles or increase the wear life?

A. Retrofitting vehicles, with older brake designs, to the new Meritor RSD friction materials will have no impact on those vehicles stopping distances. Stopping distance and wear will be comparable to existing friction materials on those vehicles.

Q. Will the new Meritor RSD materials be available for “all-makes” brakes, other than Meritor’s?

A. Meritor Aftermarket will offer the new Meritor RSD materials in a limited offering of only the most popular “all-makes” brakes. However, no testing has been conducted to show the potential impact on brake performance when retrofitting “all-makes” brakes to Meritor RSD friction materials has any impact on brake performance.

Q. How will Meritor Aftermarket supply the new Meritor RSD friction materials?

A. The new Meritor RSD friction materials will only be available on new or reman lined brake shoes and in new or reman lined brake shoe kits and disc pad sets.

Q. Will Meritor RSD friction materials be available with PlatinumShield™ II brake shoes?

RSD WARNINGMeritor RSD brakes are designed to meet the FMVSS 121 August 2011 and August 2013 stopping distance requirements for new vehicles. RSD brake assemblies must be serviced with RSD brake shoe and lining assemblies to maintain braking capability. Use of non-RSD friction material could negatively impact the safe operation of the vehicle.
