A Guide to Replacing the Disc Brake Caliper on a 2007-2009 International MXT
Keep your MXT stopping safely by understanding common caliper problems and choosing the right replacement part.
- The most common failure is a seized or sticking caliper, leading to brake drag, pulling, and overheating.
- No specific recalls for 2007-2009 MXT calipers were found, but a parking brake ECU recall (10V104000) affects some 2008 models.
- Always replace calipers in pairs (both fronts or both rears) to ensure balanced braking.
- New aftermarket calipers from brands like Dynamic Friction offer rust-resistant coatings and no core charge, while remanufactured calipers from brands like Centric are a cost-effective OE-fit option.
Is Your International MXT's Brake Caliper Failing?
A bad brake caliper is a serious safety issue. On a powerful truck like the MXT, a failing caliper can cause major problems. The most common failure is a seized or sticking caliper piston. This happens when rust, debris, or internal damage prevents the caliper's pistons from moving freely. Watch for these symptoms:
- Pulling to One Side: When you brake, the truck may pull sharply to the left or right. This can happen if one caliper is working harder than the other.
- Brake Drag: A seized caliper may not release the brake pad from the rotor. You might feel like the truck is sluggish or that the parking brake is slightly on.
- Overheating and Burning Smell: After a drive, the wheel with the dragging brake will be extremely hot. Constant friction can overheat the pads and rotor, leading to a burning smell and sometimes even smoke.
- Uneven Brake Pad Wear: When you inspect your brakes, you might find that the pads on one wheel are worn down much more than the others.
- Leaking Brake Fluid: Puddles of yellowish or brown fluid near your wheels or a dropping fluid level in the master cylinder can point to a leaking caliper seal.
Safety First: Brake System Repairs
Brake system work is critical for your safety. If you are not a qualified mechanic, you should have a professional perform the installation. Incorrect installation can lead to brake failure.
Known Issues for 2007-2009 International MXT
While searches of the NHTSA database did not show any specific recalls for the hydraulic disc brake calipers on the 2007-2009 International MXT, a related recall exists. Recall 10V104000 (Navistar #10505) was issued for some 2008 MXT models concerning the parking brake. The issue involved the brake system's electronic control unit (ECU) software, which could cause the parking brake to release unexpectedly. This recall does not apply to the service brake calipers themselves.
Although no specific caliper recalls exist for this model year, seizing or sticking calipers are a common issue on heavy-duty hydraulic brake systems of this era due to heat, moisture, and age.
Choosing the Right Aftermarket Caliper
When replacing a caliper on your MXT, you'll primarily find new and remanufactured aftermarket options. OEM calipers may be available from a dealer but are typically the most expensive choice.
New vs. Remanufactured:
- New Aftermarket Calipers: These are built from 100% new components and have never been installed on a vehicle. Brands like Dynamic Friction specialize in new calipers that are fully tested and often feature protective coatings to prevent rust.
- Remanufactured Calipers: These start with an original equipment (OE) caliper body that is cleaned, inspected, and rebuilt with new seals, boots, and pistons. Brands like Centric offer remanufactured calipers that provide an OE fit. While cost-effective, the quality of the exterior coating can vary, and some may show surface rust sooner than new coated calipers.
Available Brands: Centric and Dynamic Friction
- Centric: A well-known aftermarket brand offering a wide range of parts. Their remanufactured calipers are a popular choice and are considered a reliable, standard replacement part. For better corrosion resistance, look for their premium lines that feature a protective coating.
- Dynamic Friction (DFC): This brand focuses on providing new calipers at a competitive price point, eliminating the need for a core charge. They emphasize their 100% pressure testing and zinc coatings for durability and rust prevention, making them a strong value proposition.
Pro Tip: Replace in Pairs
It is highly recommended to replace brake calipers in pairs (both front wheels or both rear wheels at the same time). This ensures even braking performance and prevents the truck from pulling to one side. An old caliper will not perform the same as a new one.
Aftermarket Disc Brake Caliper Cost for 2007-2009 International MXT
| Part Type | Estimated Cost Range |
|---|---|
| New Aftermarket Caliper | $85 - $233 |
| Remanufactured Aftermarket Caliper | $70 - $150 |
| Shop Labor | $110 - $525 per caliper |
Frequently Asked Questions
Do I need to bleed the brakes after replacing a caliper?
Yes, absolutely. Whenever a hydraulic brake line is opened, air enters the system. The system must be properly bled to remove all air bubbles. Failure to do so will result in a spongy brake pedal and severely reduced stopping power.
Should I get a loaded or semi-loaded caliper?
A "loaded" caliper comes complete with new brake pads and all necessary mounting hardware. A "semi-loaded" or bare caliper does not include pads. If your brake pads are also due for replacement, a loaded caliper can be a convenient and cost-effective option.
What is a caliper core charge?
A core charge is a deposit you pay when buying a remanufactured part. You get the deposit back when you return your old, worn-out caliper to the seller. New calipers, like those from Dynamic Friction, typically do not have a core charge.
Can I just rebuild my old caliper?
Rebuild kits are available, but rebuilding a caliper yourself can be difficult. It requires special tools and a clean environment. Given the critical safety function and the affordable price of new or professionally remanufactured calipers, replacing the entire unit is the recommended and safer option for most owners.
Technical Specifications
The International MXT uses a hydraulic brake system. Calipers are typically made of cast iron and can be a floating or fixed design with single or multiple pistons to apply pressure to the brake pads.
