Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and set the parking brake.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Socket set
Brake cleaner
Caliper tool
Safety gloves and goggles

2. Remove Wheel Assembly

Loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using the jack and secure it with jack stands.
Remove the wheel by taking out the lug nuts completely.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set and carefully slide the caliper off the rotor.
Use the caliper tool to retract the caliper piston.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage or sticking.

4. Install New Brake Pads

Place the new brake pads into the caliper bracket.
Reinstall the caliper over the new brake pads.
Torque the caliper bolts to the manufacturer’s specifications (usually around 20-25 ft-lbs, verify with service manual).

5. Reassemble Wheel and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the proper specification (typically 100-120 ft-lbs).

6. Brake System Bleeding (if necessary)

If air was introduced into the brake lines, bleed the brake system using the appropriate method (e.g., gravity bleed or pressure bleed).
Check the brake fluid level and top off as necessary with the correct type of brake fluid.
