⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on electrical components.
•Allow the brakes to cool before working on them to avoid burns.

Symptoms

•Grinding noise when applying brakes
•Vibration felt through the brake pedal
•Decreased braking efficiency
•Brake warning light may illuminate
•Possible metallic scraping sound when driving without braking

Diagnostic Steps

1
Inspect the brake pads for wear and damage.
2
Check the brake rotors for scoring or warping.
3
Examine brake calipers for proper operation and any sticking issues.
4
Inspect the brake hardware (e.g., clips, shims) for wear or missing components.
5
Use a wheel chock and jack to lift the vehicle for detailed inspection of the braking system.

Solution

Solution

1. Preparation

Gather tools and parts:
- Tools: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench
- Safety gear: Gloves, goggles
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the socket set.
- Slide the caliper off the rotor and check the brake pads for wear. Replace if less than 1/8 inch of material remains.
Brake Rotors:
- Examine the rotor surface for grooves or scoring. If damaged, replace the rotor.
- Measure rotor thickness with a micrometer; if below manufacturer specifications, replace.
Calipers and Hardware:
- Inspect calipers for signs of sticking or damage; replace as needed.
- Ensure all brake hardware is intact and not worn out; replace clips or shims if necessary.

4. Replace Brake Pads and Rotors (if necessary)

If pads or rotors are worn, install new components:
- Brake Pads:
  - Clean the caliper bracket with brake cleaner.
  - Install new brake pads into the caliper bracket.
- Brake Rotors:
  - If replacing, install the new rotor onto the hub.

5. Reassemble Brake Components

Reattach the caliper over the new pads or rotor.
Torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle, and then fully tighten the lug nuts in a crisscross pattern to ensure even torque.
