Typically, a 7 mm Allen wrench is used to remove the caliper mounting bolts on most Dodge Durango front brakes. Some years or trims may require an 8 mm Allen head, so always verify before forcing anything.
Durango brake hardware can vary by generation and model year. The caliper is usually secured to a knuckle with two hex/Allen bolts, while the larger caliper bracket bolts use a different size. Checking the specific service manual for your year and engine is the best way to confirm the exact fastener size and torque specs. If you’re unsure, start with the 7 mm and only move to 8 mm if the 7 mm doesn’t fit snugly or rounds off.
Typical sizes and year-to-year variability
The following information covers common scenarios you might encounter on a Dodge Durango, but variations between generations and trims are possible. Use this as a guideline and confirm with your manual if possible.
- Caliper mounting bolts (the bolts that secure the caliper to the knuckle): usually 7 mm hex head.
- Backup possibility: some years may use an 8 mm hex head for the mounting bolts.
- Caliper bracket bolts (the bolts that attach the bracket to the knuckle): typically larger and not Allen-type; often require a socket such as 13–14 mm or another standard size depending on year.
Always inspect the fasteners before applying force. If a fastener looks corroded or damaged, stop and use penetrating oil and proper safety procedures, or consult the service manual for the exact specification.
Steps to remove the caliper on a Dodge Durango
Below is a general, step-by-step procedure. It assumes you’re removing the caliper to service brakes or replace pads. Always use proper jack stands and follow vehicle safety precautions.
- Prepare the vehicle: Park on a level surface, engage the parking brake, chock the wheels, and lift the front of the Durango with a jack. Secure with jack stands.
- Remove the wheel: Loosen the lug nuts, raise the vehicle, and remove the wheel to expose the brake assembly.
- Locate the caliper mounting bolts: Find the two bolts that secure the caliper to the caliper bracket on the knuckle. Have your 7 mm Allen wrench (or 8 mm if required) ready.
- Loosen and remove the caliper mounting bolts: Use the appropriate Allen key to back out the bolts. Do not force the caliper if it’s tight—check for seized bolts or debris and use penetrating oil if needed.
- Remove or swing the caliper out: Gently slide the caliper off the rotor and support it with a bungee cord or wire to avoid stress on the brake hose. Do not let the caliper hang by the hose.
- Proceed with brake service: If you’re retracting the piston, use a C-clamp or brake piston tool to compress it before installing new pads or a new caliper, then reassemble in reverse order and torque fasteners to spec.
The above steps cover the typical front caliper removal process. If you’re working on the rear brakes or a different Durango generation, some details (bolt sizes, torque specs, and procedure) may differ. Always refer to the factory service manual for your exact year and trim for precise instructions.
Summary
For most Dodge Durango models, the front caliper mounting bolts typically use a 7 mm Allen head, with 8 mm as a possible alternative on some years. Always verify against your specific year/engine service manual, and remember to support the caliper and wheel assembly safely during removal. If in doubt, consult a professional or reference the official Chrysler/Dodge service documentation for torque specs and bolt sizes.
