Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a floor jack to lift the front or rear (depending on where pulsation is felt) of the vehicle.
Secure with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel nuts.
Take off the wheel and set it aside.

4. Inspect and Replace Brake Rotors

Inspect Rotors: Check for warping and uneven surfaces.
Replace Rotors: If warped, remove the caliper bolts using a socket wrench and detach the caliper.
- Tools required: Socket set, torque wrench.
- Safety warning: Support the caliper to avoid strain on the brake line.
Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor, ensuring it sits flush against the hub. Tighten any retaining screws to the manufacturer's torque specifications.

5. Inspect and Replace Brake Pads

Remove the caliper by unbolting it, then slide the pads out of their brackets.
Inspect Pads: Look for wear indicators and replace if necessary.
Install New Pads: Apply brake grease to the backing of the new pads and slide them into place. Reattach the caliper.

6. Reassemble and Lower Vehicle

Reattach the wheel, ensuring all lug nuts are hand-tight.
Lower the vehicle and securely torque the lug nuts to the manufacturer's specifications.

7. Brake Fluid Check

Check the brake fluid level and top off if necessary with manufacturer-recommended fluid.
