⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a level surface and secured with wheel chocks before lifting.
•Always disconnect the battery when working on electrical systems associated with braking.
•Allow the brakes to cool if the vehicle was previously driven.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise when brakes are applied
•Reduced braking performance or longer stopping distances
•Brake warning light illuminated on the dashboard
•Vibration or pulsation in the brake pedal during braking
•Visible wear or thinning of brake pads during inspection

Diagnostic Steps

1
Check the thickness of the brake pads through the wheel spokes. Pads should be at least 3mm thick.
2
Drive the vehicle and listen for any unusual sounds when applying the brakes.
3
Look for any illuminated warning lights related to the brake system.
4
Ensure that the brake fluid level is within the recommended range; low fluid can affect braking performance.
5
Perform a test drive to assess braking performance and feel for any vibrations or pulling to one side.

Solution

1. Preparation

Tools Required: Socket set, jack stands, lug wrench, brake cleaner, torque wrench.
Safety Warnings: Ensure the vehicle is on a level surface and secured with wheel chocks before lifting.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Old Brake Pads

Locate the brake caliper and remove the bolts securing it using the socket set.
Carefully slide the caliper off the rotor and support it (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.

4. Inspect and Clean Components

Inspect the brake rotor for grooves or scoring; replace if necessary.
Clean the caliper and bracket with brake cleaner to remove dust and debris.
Check the caliper slides and lubricate them if needed.

5. Install New Brake Pads

Place the new brake pads into the caliper bracket in the same orientation as the old ones.
Reposition the caliper over the new pads and secure it with the bolts.
Torque the caliper bolts to the manufacturer’s specifications.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Pump the brake pedal a few times to seat the new pads against the rotors before test driving.
