Solution

1. Preparation

Tools Needed: Jack, jack stands, lug wrench, socket set, brake cleaner, and safety goggles.
Safety Warning: Ensure the vehicle is on a flat surface and securely raised using jack stands before beginning any work.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect Brake Components

Brake Pads: Remove the caliper by unscrewing the bolts holding it in place. Slide the caliper off the rotor and inspect the pads for thickness; replace if they are below the manufacturer's minimum specification.
Brake Rotors: Check the rotors for any signs of scoring or warping. If damaged, remove the rotors by unscrewing the retaining screws and replace them with new ones.
Caliper Check: Inspect the caliper for proper movement and any signs of sticking. If necessary, lubricate the sliding pins or replace the caliper.

4. Clean and Reassemble

Use brake cleaner to clean the rotor and caliper components to remove any brake dust or debris.
Reinstall the caliper over the new or cleaned rotor and secure it with bolts, ensuring proper torque as per manufacturer specifications.
Reinstall the wheel, tighten the lug nuts in a criss-cross pattern, and lower the vehicle.

5. Test Brakes

Pump the brake pedal several times to ensure the brake pads seat properly against the rotors.
Check the brake fluid level again and top off if necessary.
