Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is still on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Examine the brake pads for thickness; they should be at least 3mm thick. If they are worn or damaged, replace them.
Check the brake rotors for any signs of scoring or warping. If the surface is uneven or heavily grooved, consider replacing or resurfacing the rotors.
Inspect the calipers for any signs of sticking or damage. Ensure they move freely.

4. Replace Brake Pads and Rotors (if necessary)

If replacing pads, remove the caliper bolts using a socket wrench and gently slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
If replacing rotors, remove the rotor from the hub by unscrewing any retaining screws or using a hammer to gently tap it off if stuck.
Install new rotors and secure them with retaining screws.
Insert new brake pads into the caliper bracket, ensuring they are seated correctly.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor, ensuring it moves freely.
Torque caliper bolts to manufacturer specifications (typically 25-30 ft-lbs).
Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even pressure.

6. Final Checks

Pump the brake pedal a few times to seat the pads against the rotor.
Check brake fluid level and add fluid if necessary.
