Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Use a jack to lift the vehicle and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, brake cleaner, C-clamp
Sub-steps:
1. Inspect the brake pads for wear. If the friction material is less than 3mm, replace them.
2. Use brake cleaner to clean the caliper and rotor surfaces.
3. Compress the caliper piston using a C-clamp to allow new brake pads to fit.
4. Remove the old brake pads from the caliper bracket and install new ones.
5. Reattach the caliper to the bracket and torque the bolts to the manufacturer’s specifications (typically around 20-30 lb-ft).

4. Inspect and Replace Rotors (if necessary)

Tools Required: Torque wrench, rotor puller (if stuck), brake cleaner
Sub-steps:
1. Check the rotors for any scoring or warping. If damaged, replace them.
2. If replacing, remove the caliper and bracket to access the rotor.
3. Install new rotors and torque the bolts to manufacturer specifications (usually around 75-100 lb-ft).

5. Reassemble Components

Tools Required: Torque wrench
Sub-steps:
1. Reattach the brake caliper and ensure all bolts are properly torqued.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and then torque the lug nuts to the specified value (typically 100-120 lb-ft).

6. Final Inspection

Ensure all components are secure and there are no visible leaks.
Test the brake pedal to ensure proper feel (no sponginess or excessive travel).
