When it comes to car maintenance, one of the most critical components to check regularly is the brake pads. Brake pads are responsible for slowing down or stopping your vehicle, and worn-out brake pads can lead to serious safety issues. According to the National Highway Traffic Safety Administration (NHTSA), brake failure is a leading cause of car accidents, resulting in thousands of injuries and fatalities every year. Therefore, it is essential to know how to look at brake pads to ensure your safety on the road.
Failing to inspect brake pads regularly can lead to a range of problems, from reduced stopping power to complete brake failure. Moreover, ignoring brake pad wear can also cause damage to other brake components, such as rotors and calipers, resulting in costly repairs. In this blog post, we will guide you through the process of inspecting brake pads, helping you to identify signs of wear and tear, and providing you with the knowledge to maintain your brakes effectively.
Why Inspect Brake Pads?
Inspecting brake pads is a crucial part of car maintenance, and it’s essential to understand why it’s so important. Here are some reasons why you should inspect your brake pads regularly:
Improved safety: Worn-out brake pads can lead to reduced stopping power, increasing the risk of accidents.
Prevents damage to other brake components: Ignoring brake pad wear can cause damage to rotors, calipers, and other brake components, resulting in costly repairs.
Reduces repair costs: Inspecting brake pads regularly can help you identify wear and tear early on, allowing you to replace them before they cause damage to other components.
Enhances performance: Fresh brake pads can improve your car’s overall performance, providing better stopping power and a smoother ride.
When to Inspect Brake Pads?
It’s essential to inspect brake pads at regular intervals to ensure your safety on the road. Here are some scenarios when you should inspect your brake pads:
Every 12,000 to 15,000 miles: Most car manufacturers recommend inspecting brake pads every 12,000 to 15,000 miles.
When you notice unusual noises: If you hear unusual noises, such as grinding, squealing, or screeching, when you apply the brakes, it’s time to inspect your brake pads.
When you notice vibrations: If your car vibrates when you apply the brakes, it could be a sign of worn-out brake pads.
After a brake fluid change: When you change your brake fluid, it’s a good idea to inspect your brake pads as well. (See Also: How to Adjust Parking Brake Pedal? A Step-by-Step Guide)
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 to help you inspect your brake pads:
Step 1: Jack Up the Vehicle
Find a level surface and park your vehicle. Engage the parking brake and put the transmission in park (automatic) or first gear (manual). Locate the jacking points on your vehicle and raise it using a car jack. Make sure the vehicle is stable and secure before you start inspecting the brake pads.
Step 2: Remove the Wheel
Remove the wheel on the side you want to inspect first. You’ll need a lug wrench to loosen the lug nuts. Place the lug nuts in a safe location where they won’t get lost.
Step 3: Inspect the Brake Pads
Look for the brake caliper, which is usually located near the wheel hub. You’ll see the brake pads inside the caliper. Check the thickness of the brake pads using a brake pad wear gauge or a ruler. Compare the measurement to the manufacturer’s recommended minimum thickness.
Also, look for signs of wear and tear, such as:
Wear indicators: Some brake pads have wear indicators, which are small metal tabs that rub against the brake rotor when the pads are worn out.
Cracks or damage: Check for cracks or damage on the brake pads. If you notice any, it’s time to replace them.
Uneven wear: Check if the brake pads are wearing unevenly. If they are, it could be a sign of a more serious problem.
Step 4: Inspect the Brake Rotor
While you have the wheel removed, inspect the brake rotor for signs of wear and tear. Check for:
Warped or uneven surface: A warped or uneven surface can cause the brake pads to wear unevenly.
Scoring or grooves: Scoring or grooves on the rotor can indicate excessive wear.
Cracks or damage: Check for cracks or damage on the rotor. If you notice any, it’s time to replace it. (See Also: What Causes Loose Brake Pads? Common Signs of Wear)
How to Measure Brake Pad Thickness?
Measuring brake pad thickness is a crucial part of inspecting brake pads. Here’s how to do it:
Method 1: Using a Brake Pad Wear Gauge
A brake pad wear gauge is a specialized tool designed to measure brake pad thickness. It usually has a series of notches or markings that correspond to different thicknesses. Simply place the gauge on the brake pad and read the measurement.
Method 2: Using a Ruler
If you don’t have a brake pad wear gauge, you can use a ruler to measure the thickness. Place the ruler on the brake pad and measure the distance from the top of the pad to the metal backing plate. Compare the measurement to the manufacturer’s recommended minimum thickness.
What to Do If You Find Worn-Out Brake Pads?
If you find worn-out brake pads, it’s essential to replace them as soon as possible. Here’s what to do:
Step 1: Purchase New Brake Pads
Buy new brake pads that meet the manufacturer’s specifications. Make sure to purchase pads that are compatible with your vehicle’s make and model.
Step 2: Replace the Brake Pads
Replace the old brake pads with the new ones. Make sure to follow the manufacturer’s instructions and take necessary safety precautions.
Step 3: Bleed the Brake System
After replacing the brake pads, you’ll need to bleed the brake system to remove any air that may have entered the lines. You can use a brake bleeding kit or take your vehicle to a mechanic.
