⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is secure on jack stands before working underneath it.
•Allow brakes to cool before handling any components after driving.

Symptoms

•Grinding noise during braking
•Decreased braking efficiency
•Vibration or pulsation in the brake pedal
•Brake warning light illuminated
•Increased stopping distance

Diagnostic Steps

1
Inspect the brake pads for wear: Remove the wheel and visually examine the brake pads for thickness and condition.
2
Check the brake rotors: Look for scoring, warping, or any visible damage on the surface of the rotors.
3
Inspect brake calipers: Ensure that calipers are functioning properly and not sticking or leaking fluid.
4
Examine brake fluid level: Check the brake fluid reservoir to ensure it's at the correct level and inspect for any leaks in the system.
5
Test for debris: Look for any debris or foreign objects lodged between the brake components.

Solution

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, and safety glasses.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set and carefully lift the caliper away from the rotor.
Inspect the brake pads: If they are worn down to less than 3mm, replace them.
Remove the old pads and replace them with new ones, ensuring they are properly seated.
Torque Specification: Ensure caliper bolts are torqued to manufacturer specifications (typically around 25-30 ft-lbs for most vehicles).

4. Inspect and Resurface/Replace Rotors

Check rotor condition: If there are deep grooves or significant wear, consider resurfacing or replacing the rotors.
If resurfacing, clean the rotor surface with brake cleaner to remove any debris.
If replacing, remove the rotor retaining screws if applicable, and replace with a new rotor. Torque to manufacturer specifications.

5. Reassemble Components

Reinstall the caliper over the new or resurfaced rotor.
Secure it in place by tightening the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle

Carefully lower the vehicle from the jack stands and tighten the lug nuts to the proper torque specification in a star pattern.
