Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, caliper tool, gloves, safety glasses.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Disconnect the battery if working on electronic brake systems.

2. Raise the Vehicle

Loosen the lug nuts slightly while the car is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Components

Caliper Removal:
- Remove the caliper bolts using a socket.
- Slide the caliper off the rotor and support it with a bungee cord or hang it to avoid straining the brake line.
Brake Pad Removal:
- Remove the retaining clips if applicable.
- Slide the old brake pads out of the caliper bracket.

4. Inspect and Replace Parts

Inspect Rotor:
- Check for warping or deep grooves. If damaged, replace the rotor.
Replace Brake Pads:
- Apply a small amount of brake grease to the back of the new pads to prevent squeaking.
- Insert new pads into the caliper bracket.
Reassemble Caliper:
- If necessary, use a caliper tool to compress the piston back into the caliper.
- Position the caliper over the new pads and secure it with bolts, tightening to the manufacturer’s specifications.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then fully tighten the lug nuts in a star pattern to ensure even pressure.

6. Final Checks

Pump the brake pedal several times to seat the brake pads.
Check the brake fluid level and top off if necessary.
