•Possible grinding noise from the brakes
•Brake pedal feels pulsating or spongy

Diagnostic Steps

1
Inspect Brake Components: Visually examine brake pads, rotors, and calipers for wear or damage.
2
Check Rotor Condition: Measure rotor thickness and check for warping using a dial indicator.
3
Test Brake Pad Thickness: Measure the remaining thickness of the brake pads to ensure they are not worn beyond the minimum specification.
4
Examine Suspension and Steering Components: Check for any play in suspension parts such as control arms, tie rods, and bushings.
5
Check Wheel Alignment: Verify wheel alignment to ensure it is within manufacturer specifications.
6
Inspect Tire Condition: Look for uneven tire wear or damage that may affect vehicle stability during braking.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, dial indicator, caliper gauge.
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before working under it. Always wear safety glasses.

2. Remove Wheel

Loosen lug nuts while the vehicle is on the ground, then jack up the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts and slide the caliper off the rotor.
- Inspect the brake pads for wear; replace if below manufacturer specifications.
- If replacing, install new brake pads and ensure they are properly seated.
- Reinstall the caliper and torque the caliper bolts to the manufacturer's specifications.

4. Check and Resurface or Replace Rotors

Sub-steps:
- Use a dial indicator to check for rotor warping. If warped beyond allowed limits, replace the rotor.
- If still within limits, resurface the rotors according to the manufacturer's specifications.
- Ensure rotors are clean and free of debris before reinstallation.

5. Inspect and Repair Suspension Components

Sub-steps:
- Check for any signs of wear or damage on control arms, tie rods, and bushings.
- Replace any worn or damaged components as necessary.

6. Wheel Alignment and Tire Inspection

Sub-steps:
- After all repairs, have the vehicle's alignment checked and adjusted to manufacturer specifications.
- Inspect the tires; replace if unevenly worn or damaged.
