2021 Ford F-350 Super Duty: Brake Specs

Quick Reference: 2021 F-350 Brake Specifications

How to Choose Pads

For a heavy-duty truck like the F-350, selecting the right brake pad compound is critical for safety, performance, and longevity. Your choice largely depends on your typical usage.

• Ceramic: These pads offer the quietest operation and produce the least amount of brake dust, keeping your wheels cleaner. They are great for daily driving and light hauling, providing a smooth, consistent pedal feel. However, for heavy towing or frequent mountain descents, they may not dissipate heat as effectively as other options.

• Semi-Metallic: This is often the factory-installed compound. Semi-metallic pads contain steel fibers that help draw heat away from the rotor, offering excellent performance under a wide range of temperatures. They provide a strong initial bite and are well-suited for moderate to heavy towing. The trade-offs are more brake dust and a slightly higher potential for noise compared to ceramic pads.

• Heavy-Duty / Towing: Pads specifically marketed for "heavy-duty" or "towing" (like Power Stop's Z36 Truck & Tow series) are typically a carbon-fiber ceramic or high-performance semi-metallic hybrid. They are engineered to handle the extreme temperatures generated when stopping a heavy load, offering the most resistance to brake fade. If you frequently tow near your F-350's maximum capacity or operate in hilly terrain, this is the safest and most durable choice.

Typical Service Life

The service life of your brake pads and rotors can vary significantly based on driving habits and use case.

• Pads: For an F-350 used for daily commuting and light-duty work, expect a service life of 40,000 to 60,000 miles. For trucks that are constantly towing heavy loads or used in commercial applications, this interval can be shortened to 20,000 to 30,000 miles.

• Rotors: Rotors typically last through two sets of brake pads. With a new thickness of 40mm (front) and 36mm (rear), and a discard thickness of 37mm and 33mm respectively, there is a 3mm wear tolerance. It is often most economical and safest to replace the rotors at the same time as the pads, especially in a heavy-duty application.

Common Brake Issues for This Generation

The 2017+ Super Duty platform has robust and generally reliable brakes. However, some common issues to watch for include:

• Premature Rear Pad Wear: Due to the truck's traction control, stability control, and engine braking strategies, the rear brakes can sometimes wear more quickly than the front, which is the opposite of what many drivers expect. It's important to check rear pads regularly.

• Rotor Warping/Hot Spots: Under heavy use, especially if pads are worn thin, rotors can develop uneven surfaces or "hot spots," leading to a noticeable vibration or pulsation in the brake pedal when stopping.

• Sticking Slide Pins: The caliper slide pins must be clean and properly lubricated to allow the caliper to "float" and apply even pressure. If they seize due to corrosion or old grease, it can cause tapered pad wear and reduced braking effectiveness.

Brake Job Cost Estimate

Brake service costs depend heavily on labor rates in your area and the quality of parts used.

• DIY: If you perform the work yourself, expect to pay between $400 and $700 for a full set of quality pads and rotors (front and rear).

• Independent Shop: At an independent repair shop, a full front and rear brake job will likely cost between $800 and $1,400.

• Dealership: A Ford dealership will typically be the most expensive option, ranging from $1,200 to $2,000+ for the same service using OEM parts.
