Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery before working on electrical systems.

2. Remove the Wheel

Loosen lug nuts with a lug wrench.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors (if warped)

Remove Brake Caliper:
- Use a socket set to remove caliper mounting bolts.
- Hang the caliper with a bungee cord to avoid straining the brake line.
Remove Brake Rotor:
- Remove any retaining screws or clips holding the rotor in place.
- Slide the rotor off the hub. If stuck, use a rubber mallet to gently tap it loose.
Check Rotor Condition:
- Measure with a dial gauge. If runout exceeds specifications (usually 0.002–0.004 inches), replace the rotor.
Install New Rotor:
- Slide the new rotor onto the hub.
- Secure with retaining screws or clips.

4. Inspect and Replace Brake Pads (if necessary)

Remove Brake Pads:
- Use a caliper tool to push back the caliper piston.
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads and install them into the caliper bracket.

5. Reassemble Components

Reattach the brake caliper over the new pads.
Tighten caliper mounting bolts to manufacturer's torque specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and tighten lug nuts in a crisscross pattern.

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper caliper operation.
Test drive the vehicle to verify that the pulsating issue is resolved.
