⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted with jack stands before working underneath it.
•Allow brake components to cool before handling to avoid burns.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise indicating metal-on-metal contact
•Reduced braking effectiveness or longer stopping distances
•Vibration or pulsation in the brake pedal

Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather necessary tools and parts for brake pad inspection or replacement.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads you are inspecting.
Secure the vehicle with jack stands to ensure stability while working.

3. Remove the Wheel

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

4. Inspect Brake Pads

Locate the brake caliper and inspect the pads for thickness; they should be at least 1/8 inch thick.
Check for any cracks, tears, or signs of uneven wear on the pads.

5. Replace Brake Pads (if necessary)

5.1 Remove the brake caliper by unscrewing the caliper mounting bolts with a socket set.
5.2 Carefully slide the caliper off the rotor without stretching the brake line.
5.3 Remove the old brake pads from the caliper bracket.
5.4 Install new brake pads by sliding them into the caliper bracket.
5.5 Reinstall the caliper over the new pads and secure it by tightening the mounting bolts to the manufacturer’s torque specifications.

6. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the proper specification.

7. Test the Brake System

Pump the brake pedal to ensure the pads seat properly.
Conduct a short test drive to confirm proper braking function.
