Tools and Materials:
* New rotors: Make sure you get the correct size and type for your Ram.
* Jack and jack stands: Safety first! Never work under a vehicle supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: Essential for safety.
* Socket wrench set: Including the correct size for your lug nuts and caliper bolts.
* Torque wrench: Crucial for tightening bolts to the manufacturer's specifications.
* C-clamp or caliper compression tool: To compress the caliper piston.
* Wrench or socket for caliper bracket bolts: To remove the caliper.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted or stuck bolts.
* Gloves: Protect your hands.
* Safety glasses: Protect your eyes.
* Rotor cleaning brush (optional): For cleaning the hub.
* Anti-seize compound (optional): For easier rotor removal next time.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Raise the front of the truck using the jack and securely support it with jack stands.
2. Remove the Wheel: Use the lug wrench to remove the lug nuts and take off the wheel.
3. Remove the Caliper:
* Locate the caliper bracket bolts: These are usually on the back of the caliper.
* Apply penetrating oil: If necessary, to help loosen the bolts.
* Remove the bolts: Use the appropriate wrench or socket.
* Compress the caliper piston: Use a C-clamp or caliper compression tool to push the piston back into the caliper. This creates the space needed to remove the rotor. Be careful not to damage the piston or caliper seal. Some pistons can be turned inward; refer to your repair manual.
* Hang the caliper: Use a wire or bungee cord to securely hang the caliper out of the way. Do not let the caliper hang by the brake line.
4. Remove the Rotor: Depending on your model, the rotor might slide off or require some persuasion. A rubber mallet might be helpful to tap it loose, but avoid damaging the hub. If the rotor is rusted on, penetrating oil and gentle tapping may be necessary.
5. Clean the Hub: Use a wire brush to remove any rust, debris, or old brake material from the wheel hub.
6. Install the New Rotor: Slide the new rotor onto the hub. Ensure it fits snugly and spins freely.
7. Reinstall the Caliper: Mount the caliper back onto the bracket and secure it with the bolts. Torque the bolts to the manufacturer's specifications.
8. Reinstall the Wheel: Mount the wheel back on and tighten the lug nuts in a star pattern (opposite nuts) to ensure even pressure. Torque the lug nuts to the manufacturer's specifications.
9. Lower the Vehicle: Carefully lower the truck from the jack stands.
10. Test the Brakes: After reinstalling everything, test the brakes carefully to ensure they are functioning properly. A test drive is recommended.
Important Notes:
* Always refer to your vehicle's repair manual for specific instructions and torque specifications. This is crucial for safe and proper installation.
* If you are uncomfortable performing this repair yourself, take your vehicle to a qualified mechanic. Brake systems are critical for safety.
* If the rotors are severely worn or damaged, you may also need to replace the brake pads. Inspect them carefully and replace them if necessary.
This is a general guide. Specific steps and tools might vary slightly depending on your Dodge Ram's year and model. Always prioritize safety and consult your owner's manual or a professional if you have any doubts.
