⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise when brakes are applied
•Reduced braking performance or longer stopping distances
•Vibration or pulsation in the brake pedal
•Warning light illuminated on the dashboard (if equipped)
•Visual wear indicators visible on the brake pads

Diagnostic Steps

1
Inspect the brake pads visually through the wheel spokes for thickness.
2
Listen for any unusual noises during braking, such as squeaking or grinding.
3
Check the brake fluid level in the master cylinder; low levels may indicate wear.
4
Perform a test drive to assess braking performance and feel.
5
Use a caliper tool to measure the thickness of the brake pads.
6
Inspect the rotors for signs of wear or damage.

Solution

Diagnostic Steps

2

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, brake caliper tool, torque wrench, and socket set.
Wear safety goggles and gloves.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.

2. Lift the Vehicle

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

3. Remove Caliper and Brake Pads

Locate the brake caliper and remove the bolts securing it (typically two bolts).
Carefully slide the caliper off the rotor and support it with a bungee cord or a wire to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.

4. Inspect Components

Check the condition of the rotor; if it shows grooves or excessive wear, consider resurfacing or replacing it.
Inspect caliper slides for smooth movement; lubricate if necessary.

5. Install New Brake Pads

Place the new brake pads into the caliper bracket.
If the brake caliper piston needs to be retracted, use a brake caliper tool to push the piston back into the caliper.
Reinstall the caliper over the new pads and secure it with the bolts (torque to manufacturer specifications).

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts in a crisscross pattern to the recommended torque specification.

7. Test

Pump the brake pedal several times to ensure proper pad seating and brake function before driving.
