Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Inspect Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Remove the brake pads from the caliper bracket.
Inspect the pads for wear. If the friction material is less than 3mm thick or if there is uneven wear, replace the pads.

3. Check Brake Rotors

Visually inspect the rotors for grooves, scoring, or warping.
If warped, replace rotors with new ones. If they are within specifications, clean the surface with brake cleaner.
Ensure that the rotor thickness is within manufacturer specifications.

4. Inspect Calipers

Check the caliper for any signs of damage, leaks, or seized pistons.
If the caliper is sticking, it may need to be rebuilt or replaced.

5. Reassemble Components

Reinstall new brake pads (or cleaned pads) into the caliper bracket.
Slide the caliper back over the pads and rotor.
Torque caliper bolts to manufacturer's specifications.
Reinstall the wheel and lower the vehicle.
