Signs and Symptoms of Worn-Out Brake Pads
Before we dive into the inspection process, let’s cover some common signs and symptoms of worn-out brake pads. These include:
- Squealing or Grinding Noises: When brake pads are worn down, they can cause a high-pitched squealing or grinding noise when you press the brake pedal. This is usually due to the metal backing plate making contact with the rotor.
- Vibrations or Shuddering: Worn-out brake pads can cause your vehicle to vibrate or shudder when you brake, especially if the pads are severely worn.
- Soft or Spongy Brake Pedal: If your brake pedal feels soft or spongy, it may be a sign that your brake pads are worn out.
- Increased Stopping Distance: If your vehicle takes longer than usual to stop, it may be a sign that your brake pads are worn out.
- Brake Light on the Dashboard: Many modern vehicles have a brake light on the dashboard that illuminates when the brake pads are worn out.
How to Inspect Brake Pads
Inspecting brake pads is a relatively simple process that you can do yourself with a few tools. Here’s a step-by-step guide:
Tools Needed
- Wheel chocks
- Jack stands
- A lug wrench
- A socket wrench
- A brake pad inspection tool (optional)
Step 1: Jack Up the Vehicle
Before you start inspecting the brake pads, make sure the vehicle is safely jacked up and supported by jack stands. This will give you clearance to work underneath the vehicle.
Step 2: Remove the Wheels
Remove the wheels to access the brake calipers and brake pads. You may need to use a lug wrench to loosen the lug nuts.
Step 3: Remove the Caliper
Use a socket wrench to loosen the caliper bolts and remove the caliper. Be careful not to damage the brake hose or ABS sensor wires.
Step 4: Inspect the Brake Pads
