Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the brake components to cool before handling after driving.

Symptoms

•Grinding noise when applying brakes
•Reduced braking performance
•Brake pedal vibration or pulsation
•Warning light on the dashboard (if applicable)
•Increased stopping distance

Diagnostic Steps

1
Inspect the brake pads for wear; check for thickness and uneven wear patterns.
2
Examine the brake rotors for scoring, warping, or damage.
3

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench, safety glasses, gloves.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Wheel Removal

Loosen the lug nuts on the wheel where the grinding noise is occurring.
Use the jack to lift the vehicle and support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Pad and Rotor Inspection

Inspect the brake pads for thickness; they should be at least 3mm thick. Replace if they are worn down.
Check the brake rotor's surface for scoring or grooves. Measure rotor thickness with a micrometer; replace if below specifications.
If necessary, replace the rotors and pads:
- Remove caliper bolts using a socket set.
- Slide the caliper off the rotor and suspend it using a wire or bungee cord.
- Remove the old brake pads from the caliper bracket.

4. Component Replacement

Install new brake pads in the caliper bracket.
If replacing rotors, remove the old rotor and install the new rotor on the hub.
Reinstall the caliper over the new pads and rotor, ensuring it aligns properly.
Tighten caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and use a torque wrench to tighten the lug nuts to the manufacturer's specification (typically 76 ft-lbs).
Reconnect the battery.
