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.
Disconnect the negative battery terminal to avoid electrical issues.

2. Replace Brake Pads

Tools Required: Jack and jack stands, lug wrench, socket set, brake pad spreader, torque wrench.
Remove the wheels using the lug wrench.
Unbolt the caliper using the socket set and carefully hang it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage or leaks.

3. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotors for any grooves or damage. If they are below the minimum thickness specification, they need to be replaced.
Tools Required: Brake rotor puller, torque wrench.
Remove the old rotor by unbolting it from the hub.
Clean the hub surface to ensure proper contact with the new rotor.
Install the new rotor, securing it with the appropriate bolts and torquing to the manufacturer’s specifications.

4. Reassemble Brake Components

Install the new brake pads into the caliper bracket.
Compress the caliper piston using a brake pad spreader to allow for the thicker new pads.
Reattach the caliper over the new brake pads and secure it with bolts, torquing to the manufacturer’s specifications.
Reinstall the wheel and tighten the lug nuts in a crisscross pattern.

5. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the new pads.
Check the brake fluid level and top off if necessary.
