⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the brake components to cool before working on them.
•Ensure the vehicle is securely supported with jack stands before working underneath it.

Symptoms

•Grinding noise when applying brakes
•Reduced braking efficiency or responsiveness
•Vibration felt through the brake pedal
•Possible illuminated brake warning light on the dashboard
•Brake pads may appear worn or damaged upon inspection

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual check.
2
Check brake rotors for scoring or warping by removing the wheel.
3
Inspect calipers for proper functioning and signs of sticking or damage.
4
Measure brake fluid level and inspect for contamination or leaks.
5
Scan the vehicle's OBD-II system for any related brake system error codes.

Solution

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual check.
2
Check brake rotors for scoring or warping by removing the wheel.
3
Inspect calipers for proper functioning and signs of sticking or damage.
4
Measure brake fluid level and inspect for contamination or leaks.
5

Solution

1. Preparation

Gather tools: socket set, torque wrench, brake cleaner, jack stands, and a lug wrench.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack, then support it securely with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor; support it with a bungee cord or similar device to avoid strain on the brake line.
Inspect the brake pads for wear; replace them if they are below the manufacturer’s specified thickness (usually 3mm or less).
If replacing, remove the old pads and install new ones, ensuring they are secured correctly.

4. Inspect and Resurface or Replace Rotors

Check the rotors for scoring, warping, or excessive wear.
If they are within specifications, clean them with brake cleaner and a clean rag.
If damaged or below thickness specifications, replace the rotors with new ones.
Ensure the new rotors are properly torqued to the manufacturer’s specifications (typically 80-100 ft-lbs).

5. Reassemble and Test

Reattach the caliper over the new brake pads and secure it with caliper bolts.
Reinstall the wheel, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the specified value (usually 80-100 ft-lbs).
Reconnect the battery and check the brake fluid level, topping off if necessary.
