How to Figure Out Which Calipers You Have on Your 2002-2006 Sprinter Van

dentifying the calipers on your 2002-2006 Sprinter Van (T1N) is essential for maintenance and replacement. Here’s a step-by-step guide to determine which calipers are installed:

1. Understand the Basics of Your Sprinter

  • The 2002-2006 Sprinter Vans were sold under Dodge, Freightliner, or Mercedes-Benz branding, and caliper compatibility depends on:
    • Model: 2500 (single rear wheels) or 3500 (dual rear wheels).
    • Trim level and load capacity.
  • Key Brake Configurations:
    • Front and rear calipers differ.
    • Brake systems were supplied by brands like ATE or Bosch.

2. DONT Locate Your Vehicle Identification Number (VIN) Unfortunately this is not a fool proof way to figure out what you have on your van, as we have found that everyone’s database is not the same or has correct information.

3. Inspect the Existing Calipers

  • Remove the Wheels: Safely jack up the van and remove the wheels to access the calipers.
  • Look for Identifying Marks:
    • Part Numbers: Usually cast or stamped on the caliper body.
    • Brand Names or Logos: Common suppliers for T1N Sprinters include ATE and Bosch.
  • Design Characteristics:
    • 2500 Model: Lighter-duty single-piston calipers.
    • 3500 Model: Heavy-duty dual-piston calipers.

4. Measure the Rotors

  • Brake calipers are designed to fit specific rotor sizes. If the caliper markings are unclear, measuring the rotor can help narrow it down:
    • Front Rotors:
      • 2500 Model: Approximately 11 inches (smaller size).
      • 3500 Model: Around 13 inches (larger size).
    • Rear Rotors: Typically smaller than front rotors, with a size variation between 2500 and 3500 models.
  • Use a tape measure or caliper tool for accuracy.

5. Check Brake System Components

  • Verify if your Sprinter has floating calipers (common on lighter models) or fixed calipers (used for heavier-duty applications).
  • Examine:
    • Number of pistons.
    • Mounting bracket style.
    • Compatibility with brake pads.

6. Cross-Reference Part Numbers

  • If you find a part number, cross-reference it with online databases or auto parts stores like RockAuto, Europarts SD, or FCP Euro.
  • Check the manufacturer’s specifications or use an OEM parts catalog to confirm the caliper type.

7. Consult a Dealer or Expert

  • Contact a Mercedes-Benz, Dodge, or Freightliner dealer with your VIN or part numbers for confirmation.
  • Alternatively, consult online communities like Sprinter-Source.com, where other T1N owners can share insights about their brake systems.

9. Check Service Records or Manuals

  • If you have the original service manual, it often specifies the exact caliper type.
  • Review service history for past replacements, which may give clues about the existing parts.

10. Take Photos and Seek Assistance

  • If you’re unable to identify the calipers, take clear photos of them and share them with:
    • Online forums or auto parts retailers.
    • Mechanics or experts specializing in Sprinter vans.

By following these steps, you’ll be able to accurately determine which calipers are installed on your 2002-2006 Sprinter Van, ensuring you get the correct replacements for your vehicle.
