Product Details

This Dynamic Friction disc brake caliper is part of the DFC Premium Caliper - Silver Zinc Coated line, a product line focused on replacement calipers with a protective silver zinc coating. For Ram 2500 and Ram 3500 SRW rear right brake service, 331-40680 provides the correct caliper configuration with a phenolic piston material and a 48 mm piston diameter. The phenolic piston construction is commonly used to reduce heat transfer compared with metal piston designs, while the included bleeder screw supports brake bleeding during service.

Use this caliper when replacing a worn, sticking, leaking, or corroded rear right caliper on a Ram 2500 or Ram 3500 SRW. The fitment is specific to the listed rear right position, so matching the vehicle, axle configuration, and side is important before ordering. Part number 331-40680 is the reference to verify against your existing brake hardware.

Common Repair Reasons

• Rear brake drag caused by a seized caliper piston
• Brake fluid leakage at the caliper body or bleeder area
• Uneven rear braking or pull during stops
• Corrosion on the caliper housing or piston area
• Reduced braking performance from a worn rear right caliper

Installation Notes

Confirm rear right placement before installation and compare the old caliper to the new unit for piston size, bleeder location, and mounting points. Inspect brake pads, rotors, and flexible brake hoses during service, and bleed the hydraulic system after installation to remove air from the circuit. Because pads are not included, reuse or replace pads separately as needed based on wear condition.

Quality Assurance

Dynamic Friction identifies this as a DFC Premium Caliper - Silver Zinc Coated replacement part for the listed Ram applications. Verify part number 331-40680 against your vehicle and brake system before installation to ensure the correct rear right fitment.
