⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Ensure the vehicle is on a flat surface and the parking brake is engaged before starting work.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise indicating metal-to-metal contact
•Vibration or pulsation in the brake pedal during braking
•Warning light illuminated on the dashboard (brake pad wear indicator)
•Reduced braking efficiency or longer stopping distances
•Visual inspection shows less than 3mm of pad thickness

Diagnostic Steps

1
Inspect the brake pads visually through the wheel spokes for thickness.
2
Listen for any unusual noises during braking, such as squeals or grinding.
3
Check for warning lights on the dashboard related to brake wear.
4
Perform a brake pedal test for any vibrations or pulsations.
5
Measure brake pad thickness with a caliper if accessible.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safely elevate the vehicle using jack stands.

2. Remove Wheel

Tools Required: Socket set, torque wrench.
Loosen lug nuts while the vehicle is on the ground.
Raise the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Remove Brake Pads

Locate the brake caliper and check for any rust or debris.
Tools Required: Brake caliper tool, socket set.
Remove the caliper mounting bolts and detach the caliper from the rotor.
Carefully hang the caliper using a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.

4. Install New Brake Pads

Tools Required: Brake grease, torque wrench.
Apply brake grease to the back of the new pads to prevent noise.
Install the new brake pads in the caliper bracket.
Compress the caliper piston using a brake caliper tool to make room for the new pads.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads.
Torque the caliper mounting bolts to the manufacturer's specifications (usually around 30 Nm).
Reinstall the wheel and torque lug nuts to the specified value (typically 120 Nm).

6. Final Checks

Lower the vehicle and pump the brake pedal to ensure proper pad seating.
Conduct a test drive to verify the brake performance.
