•Pulsating brake pedal

Diagnostic Steps

1
Inspect brake rotor surfaces for warping or scoring using a dial indicator.
2
Check brake pad thickness and condition for uneven wear or damage.
3
Examine suspension components (control arms, bushings, and ball joints) for wear or damage.
4
Perform a wheel balance check to rule out tire issues.
5
Inspect wheel bearings for play or roughness.
6
Scan for any ABS-related error codes using an OBD-II scanner.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery before starting work on electronic components.

2. Wheel Removal

Loosen the lug nuts on the front wheels while the vehicle is still on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the front wheels.

3. Brake Inspection

Inspect Rotors:
- Measure rotor thickness with a micrometer to ensure it meets minimum specifications.
- Check for warping with a dial indicator; replace if warped beyond specification.
Inspect Brake Pads:
- Remove the caliper bolts and slide the caliper off the rotor.
- Inspect brake pads for thickness; replace if worn below the manufacturer’s specifications.
Clean Components:
- Use brake cleaner to remove dust and debris from the caliper, rotor, and pads.

4. Suspension and Wheel Bearing Check

Inspect Suspension:
- Check bushings and ball joints for play or damage.
- Replace any worn components as necessary.
Check Wheel Bearings:
- Spin the wheel hub; listen for grinding noises and check for excessive play.
- Replace wheel bearings if they exhibit signs of wear.

5. Reassembly

Reinstall the brake caliper and ensure it is securely fastened.
Put the wheels back on and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications.

6. Test Drive

Once reassembled, conduct a test drive to verify the issue has been resolved.
Monitor the braking performance for any remaining vibration or shaking.
