⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath it.
•Allow brakes to cool before inspection or repair to avoid burns.

Symptoms

•Squeaking or squealing noise when applying brakes
•Grinding noise when brakes are engaged
•Reduced braking responsiveness or increased stopping distance
•Vibration or pulsation in the brake pedal during braking
•Warning light illuminated on the dashboard
•Brake pedal feels soft or spongy

Diagnostic Steps

1
Inspect brake pads visually through the wheel spokes for wear indicators.
2
Measure the thickness of the brake pads using a caliper; pads below 1/8 inch (3mm) should be replaced.
3
Listen for unusual noises while engaging the brakes during a test drive.
4
Check for brake fluid level in the reservoir; low fluid may indicate worn pads.
5
Inspect rotors for scoring or grooves during brake pad inspection.

Solution

Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Use a jack to lift the vehicle and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Remove the wheel to access the brake assembly.

3. Remove Brake Caliper

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the rotor without stressing the brake line.
Secure the caliper with a bungee cord or hang it to avoid tension on the brake line.

4. Replace Brake Pads

Remove the old brake pads by sliding them out of the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads into the caliper bracket ensuring proper orientation.

5. Reassemble Brake Components

Reinstall the brake caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically around 20-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specification (typically around 75-80 ft-lbs).
Pump the brake pedal a few times to seat the new pads.
