• FMVSS 121 Performance Requirements: Manufacturer literature identifies compliance with applicable requirements, including reduced stopping distance mandates.
• R90 Performance Requirements: Listed as meeting R90 specifications.
• Independent Wear Testing: Manufacturer reports reduced pad wear and friction material loss compared with multiple OE edge-code products tested.
• Axle Service Kit: Includes brake pads and associated replacement hardware for one compatible axle.

Heavy-Duty Air Disc Brake Pads for Semi Trucks

Air disc brakes are widely used on modern commercial trucks and trailers because of their braking performance and serviceability. Maintaining proper brake pad thickness, rotor condition, and caliper operation is essential for safe vehicle operation.

The OTR OTRD1369 air disc brake pads are designed for compatible heavy-duty air disc brake assemblies and are suitable for applications such as:

• Class 7 and Class 8 commercial trucks
• Over-the-road semi trucks
• Commercial truck tractors
• Heavy-duty trailers with compatible air disc brakes
• Fleet maintenance vehicles
• Vocational trucks
• Commercial transportation equipment

Fitment depends on the installed brake caliper system, not the vehicle brand alone. Confirm the caliper model and original brake pad identification before ordering.

Compatible Bendix ADB22X & Knorr SK7 Brake Systems

The OTRD1369 brake pad kit is designed for compatible Bendix ADB22X and Knorr-Bremse SK7 air disc brake caliper systems using the D1369 pad configuration.

These caliper systems may be installed on various commercial trucks and trailers. The correct pad selection depends on the brake assembly, friction specification, and service requirements.

Important: This kit should not be assumed interchangeable with pads for Bendix SB7/SN7, Meritor EX225, WABCO PAN, or other air disc brake systems simply because the vehicle uses air disc brakes.

Cross-Reference Note: Part numbers are provided for identification and interchange research. Brake pad friction formulations, hardware, and service requirements may vary. Confirm the correct replacement using the original part number and brake manufacturer's specifications.

Copper-Free Friction Material & Rotor Protection

The OTRD1369 features a copper-free friction formulation designed to support dependable braking while minimizing rotor wear.

The friction material is mechanically attached to the backing plate to provide additional shear strength and help reduce the risk of friction material separation under demanding operating conditions.

Post-Cured Brake Pads for Reduced Initial Break-In

OTR air disc brake pads are post-cured and treated with aluminum oxide to help reduce the initial break-in period.

Always follow the brake system manufacturer's installation, inspection, and bedding procedures. Brake performance depends on proper installation and the condition of the complete braking system.

When Should You Replace Air Disc Brake Pads?

Regular brake inspections help identify worn components before they affect braking performance or damage other parts of the brake assembly.

Common reasons for brake pad replacement include:

• Friction material reaching the manufacturer's minimum allowable thickness
• Uneven brake pad wear
• Cracked, damaged, or contaminated friction material
• Brake rotor damage associated with worn pads
• Abnormal braking noise or vibration
• Brake caliper or wheel-end repairs requiring pad replacement

Inspect the brake rotor, caliper guide pins, tappets, adjuster operation, and associated hardware when replacing air disc brake pads.

Brake Pad Installation & Fitment Verification

Before purchasing, verify that your vehicle uses the correct Bendix ADB22X or Knorr SK7 brake system and that the required pad configuration matches FMSI D1369.

Air disc brake service should be performed according to the brake manufacturer's maintenance procedures, including inspection of rotor thickness, caliper movement, brake pad retention hardware, and related components.

Professional Installation Recommended: Commercial vehicle braking systems are safety-critical. Incorrect brake pads, damaged components, or improper installation can compromise braking performance. Always verify the correct application and complete all required inspections before returning the vehicle to service.
