This guide outlines the general process. Always consult your vehicle's repair manual for specific torque specifications and procedures for your exact model and trim level. These instructions assume you're replacing the front disc brakes; rear drum brakes are a different process.
Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: To prevent the car from rolling.
* Socket wrench set: Various sizes, including those needed for caliper bolts, lug nuts, and possibly brake line bolts.
* Wrench set: Possibly needed for caliper bracket bolts.
* C-clamp or caliper compressor: To compress the caliper piston.
* Brake caliper pliers: To help with caliper piston compression.
* Screwdrivers: Phillips and flathead, possibly needed for caliper bracket bolts.
* Penetrating lubricant (PB Blaster or similar): To help loosen rusted bolts.
* New brake pads: Get the correct ones for your vehicle.
* New rotors (optional): If the rotors are worn or scored, they should be replaced.
* Grease: For lubricating caliper pins.
* Shop rags or paper towels: To clean up brake dust and fluid.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes from flying debris.
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Jack up the car and securely place it on jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper:
* Locate the caliper mounting bolts. There are usually two.
* Spray penetrating lubricant on the bolts and let it sit for a few minutes.
* Use a socket wrench to carefully remove the bolts.
* Support the caliper with your hand or a bungee cord to prevent it from hanging by the brake line. This is important to avoid stressing the brake line.
4. Compress the Caliper Piston:
* Use a C-clamp or caliper compressor tool to push the piston back into the caliper. You may need to rotate the piston as you compress it. Be careful not to damage the piston or the dust boot. Brake fluid will likely come out, so have rags ready.
5. Remove the Old Brake Pads: The pads should simply slide out of their holders.
6. Install the New Brake Pads: Install the new brake pads into their holders.
7. Install the Caliper: Carefully reinstall the caliper onto the caliper bracket, making sure the caliper pins slide smoothly. Lubricate the caliper pins with grease. Tighten the caliper bolts to the manufacturer's specifications.
8. Install the Rotor (If Replacing): If you're replacing the rotor, carefully remove the old one and install the new one.
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts. Don't overtighten!
10. Lower the Car: Carefully lower the car to the ground.
11. Repeat for the Other Side: Repeat steps 2-10 for the other front wheel.
12. Pump the Brakes: Get in the car and pump the brake pedal several times to re-establish brake pressure.
Important Considerations:
* Brake Fluid: If you are replacing the brake lines or doing a major overhaul, be aware that you will need to bleed the brakes afterwards to remove air bubbles in the lines. This is a more advanced procedure.
* Rotor Condition: Inspect the rotors carefully for wear and scoring. If they're damaged, they need to be replaced.
* Caliper Condition: Inspect the calipers for leaks and proper operation. If you find any damage, replacement may be necessary.
* Torque Specifications: Always follow the torque specifications in your vehicle's repair manual. Overtightening bolts can damage parts.
This is a simplified guide. Again, refer to a repair manual specific to your 2003 Dodge Stratus for detailed instructions and torque specifications. If you're unsure about any step, seek professional help. Improper brake installation can lead to dangerous situations.
