Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for wear and proper installation.
3
Examine brake calipers for sticking or malfunctioning components.
4
Inspect brake fluid level and condition.
5
Test drive the vehicle to replicate the pulsation and assess braking performance.

Solution

1. Preparation

Gather tools and equipment: jack, jack stands, lug wrench, dial indicator, torque wrench, and a basic socket set.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts slightly while the tire is still on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the wheel by taking off the lug nuts completely.

3. Inspect Brake Components

Brake Rotors:
- Use a dial indicator to measure rotor runout.
- If warping exceeds manufacturer specifications (typically 0.002 inches), replace the rotor.
Brake Pads:
- Check the thickness of the brake pads and inspect for uneven wear.
- Replace if the thickness is below the minimum specification (usually 3 mm).
Brake Calipers:
- Ensure calipers are moving freely; check for any signs of sticking or damage.
- If calipers are faulty, they should be replaced.

4. Replace Parts if Necessary

If rotors or pads are worn out, replace them as follows:
- Rotors:
  - Remove the caliper bracket using the appropriate socket.
  - Slide the rotor off the hub. Clean the hub surface before installation.
  - Install the new rotor, ensuring it is properly seated.
- Brake Pads:
  - Remove the old pads from the caliper bracket.
  - Install the new pads, ensuring they are oriented correctly and seated properly in the caliper bracket.

5. Reassemble Components

Reinstall the caliper bracket and torque to manufacturer specifications (typically 75-85 ft-lbs).
Reinstall the wheel, tightening the lug nuts by hand first, then torque to specifications (usually 100-120 ft-lbs) in a criss-cross pattern.
Lower the vehicle and perform a final inspection of the brake assembly.
