Choosing the Right Disc Brake Pads for Your 2007-2011 Workhorse W62
Stopping power is critical for your heavy-duty chassis; here's what you need to know before buying new brake pads.
- Crucially, inspect for sticking brake calipers—a known recall issue on W-series chassis—before changing pads to prevent repeat failure.
- Choose only heavy-duty semi-metallic, carbon-metallic, or severe-duty ceramic pads from reputable brands like Bendix, Wagner, or Performance Friction.
- Symptoms like a burning smell or a soft pedal are critical warnings of a potential caliper failure, not just worn pads.
- Due to the vehicle's weight, investing in premium pads is a critical safety measure, not an optional upgrade.
Symptoms of Failing Brake Pads
Worn brake pads will give you clear warning signs. Ignoring them can lead to more expensive repairs and unsafe driving conditions. Look out for these symptoms:
- Squealing or Screeching Noises: Most brake pads have a small metal tab called a wear indicator. When the pad material wears down, this tab scrapes against the rotor, making a high-pitched noise to alert you it's time for a replacement.
- Grinding Sounds: If you hear a deep, metallic grinding, it means the pad material is completely gone. The metal backing plate of the pad is now grinding against the rotor, causing severe damage and significantly reducing your stopping power. Stop driving the vehicle immediately.
- Spongy or Soft Brake Pedal: If your brake pedal feels less responsive or sinks towards the floor, it could indicate a problem with the hydraulic system, possibly caused by overheating from worn or dragging brakes.
- Vehicle Pulling to One Side: If the vehicle pulls to the left or right when you brake, it could mean the pads are worn unevenly or there is a problem with a brake caliper.
- Increased Stopping Distance: If you notice it's taking longer to stop your truck, your brake pads may be worn out and unable to create the necessary friction.
Known Issue: Sticking Brake Calipers on Workhorse Chassis
Before you replace your brake pads, you MUST be aware of a major safety recall concerning the Bosch brake calipers on many Workhorse W-series chassis, including models in the 2007-2011 range. The issue involves caliper pistons that can stick, causing the brake pads to constantly drag against the rotor. This is often caused by moisture absorption in the pistons, especially on vehicles that sit for long periods.
Symptoms of a sticking caliper are often mistaken for bad pads, but are more severe:
- A strong burning smell from the wheels.
- Noticeable brake drag, where the truck feels sluggish or requires more power to move.
- Smoke coming from a wheel after driving.
- Extreme, rapid, and uneven brake pad wear.
- Cracked rotors and pads that look crumbled or have material melted onto the rotor.
Pro Tip: If you are replacing pads, have your mechanic carefully inspect all brake calipers for smooth operation. A new set of pads will be quickly destroyed by a sticking caliper, wasting your money and creating a dangerous situation. The official recall remedy was to replace all four caliper assemblies.
Choosing the Right Aftermarket Brake Pads
For a Workhorse W62, not just any brake pad will do. You need a pad designed for heavy-duty use. Organic pads, the cheapest option, are not recommended as they cannot handle the heat and wear out too quickly. Focus on semi-metallic, heavy-duty ceramic, or carbon-metallic pads. Here’s a breakdown of quality tiers for available brands:
Premium / Severe-Duty Pads
These are the best option for vehicles that are heavily loaded, used for towing, or operate in hilly terrain. They offer the best stopping power and heat resistance.
- Performance Friction: Their Carbon Metallic pads are specifically engineered for severe-duty use. They are known for providing excellent stopping power at high temperatures, resisting brake fade, and offering a longer service life, which is ideal for a heavy W62 chassis.
Professional Grade / Heavy-Duty Pads
These brands are trusted by professional mechanics and offer excellent durability and performance that meets or exceeds OEM standards for commercial applications.
- Bendix: The Bendix FleetMetlock line is designed specifically for the rigors of commercial and fleet vehicles, making it a perfect match for the W62. They provide reliable stopping power and long life in demanding conditions.
- Wagner Brakes: Wagner is a top name in heavy-duty braking. Their Wagner SD (Severe Duty) or ThermoQuiet lines offer robust performance, good heat dissipation, and are engineered for trucks and frequent-stopping applications.
Performance-Focused Aftermarket Pads
These pads offer a potential upgrade in bite and pedal feel over standard replacements, but may have trade-offs.
- Dynamic Friction: Their "Ultimate Duty" or "Heavy Duty" semi-metallic pads are engineered for trucks and towing. They provide aggressive stopping power and a confident pedal feel, but some users report they can produce more brake dust than other options.
| Item | Estimated Cost |

Frequently Asked Questions (FAQ)
Do I really need to worry about the caliper recall?
Yes, absolutely. The sticking caliper issue is the most significant known problem for this chassis. Even if the recall work was previously done, calipers can still fail. Any brake job on a W62 must include a thorough caliper inspection to ensure the pistons and guide pins move freely. Replacing only the pads on a vehicle with a sticking caliper will lead to a repeat failure in a very short time.
What's the difference between semi-metallic and ceramic pads for my W62?
For a heavy truck, a high-quality semi-metallic or a severe-duty ceramic pad is best. Semi-metallic pads are excellent at dissipating heat and provide great stopping power, but can sometimes be noisier and produce more dust. Heavy-Duty Ceramic pads (different from typical passenger car ceramics) are designed for quiet operation and low dust, while still providing strong, fade-resistant performance suitable for trucks. For the W62, a semi-metallic or a premium carbon-metallic pad is often the safest bet for maximum performance under load.
How can I tell if my brake pads are worn or if my caliper is sticking?
A high-pitched squeal usually points to normal pad wear. A deep grinding noise means the pads are completely gone. However, symptoms like a strong burning smell, the truck feeling like it's being held back (brake drag), and a soft or spongy brake pedal are classic signs of a sticking caliper causing extreme heat. If you suspect a sticking caliper, have the vehicle inspected immediately.
Is it worth paying for premium severe-duty brake pads?
For the Workhorse W62, yes. This is not a lightweight passenger car. Whether it's used as a step van or an RV, it's a heavy vehicle that puts enormous stress on its brakes. Premium pads from brands like Performance Friction, Bendix, or Wagner are designed to handle the high heat generated during braking without fading. This ensures you have consistent, reliable stopping power when you need it most, which is a non-negotiable for safety.
