⚠️ Safety Warnings

Important safety information - read before proceeding

•Always engage the parking brake and use wheel chocks for safety.
•Disconnect the battery before working on electrical systems (if necessary).
•Allow the vehicle's exhaust system to cool before working underneath.

Symptoms

•Screeching noise when applying brakes
•Vibration or pulsation in the brake pedal
•Decreased braking efficiency
•Warning light illuminated on the dashboard (if applicable)
•Brake dust accumulation on wheels

Diagnostic Steps

1
Inspect brake pads for wear: Remove the wheel to visually examine the brake pads.
2
Check brake rotor condition: Look for scoring or warping on the rotors.
3
Measure brake pad thickness: Use a caliper to confirm if pads are within acceptable thickness limits.
4
Inspect brake hardware: Check for damaged or missing shims, clips, or other components.
5
Perform a test drive: Listen for noise under various braking conditions to isolate the issue.

Solution

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a caliper gauge.
Ensure the vehicle is on a flat surface and turn off the ignition.
Safety Warning: Always engage the parking brake and use wheel chocks for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads with a caliper gauge. If they are worn down (typically below 3mm), proceed to replace.
Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
Suspend the caliper using a wire or bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Apply brake cleaner to clean the caliper bracket and rotor.
Install new brake pads in the caliper bracket ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, remove the caliper bracket and then the rotor.
Use a torque wrench to ensure the new rotor is installed to manufacturer specifications.
Reinstall the caliper bracket over the new rotor.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure it with the caliper bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle, then torque the lug nuts to the manufacturer's specifications.
Test the brake system by applying pressure on the pedal to ensure the pads seat properly.
