Brake discs are an essential component of a vehicle’s braking system, responsible for converting the kinetic energy of the vehicle into heat energy through friction. Over time, brake discs can wear out, leading to a decrease in braking performance, increased stopping distances, and potentially even a loss of control while driving. Regularly checking brake discs is crucial to ensure the safety and reliability of a vehicle. In this comprehensive guide, we will walk you through the process of how to check brake discs, highlighting the importance of this maintenance task and providing step-by-step instructions for a thorough inspection.

Why Check Brake Discs?
Brake discs are a critical component of a vehicle’s braking system, and their condition can significantly impact the overall performance and safety of the vehicle. Worn-out brake discs can lead to a range of problems, including:
- Increased stopping distances: Worn-out brake discs can cause the vehicle to take longer to stop, increasing the risk of accidents.
- Reduced braking performance: Worn-out brake discs can lead to a decrease in braking power, making it more difficult to stop the vehicle.
- Increased risk of wheel damage: Worn-out brake discs can cause the wheel to vibrate excessively, leading to damage to the wheel and other components.
- Increased risk of brake failure: Worn-out brake discs can lead to a complete failure of the braking system, putting the driver and passengers at risk.
Regularly checking brake discs is essential to ensure the safety and reliability of a vehicle. By identifying worn-out brake discs early, drivers can take corrective action to replace them before they cause any damage or compromise the safety of the vehicle.
Tools and Equipment Needed
To check brake discs, you will need the following tools and equipment:
- A lug wrench (or tire iron)
- A socket wrench or ratchet and socket
- A brake cleaner
- A pair of gloves
- A flashlight (optional)
It’s also a good idea to consult your vehicle’s owner’s manual for specific instructions on how to check brake discs on your particular vehicle.
Step 1: Raise the Vehicle
To access the brake discs, you will need to raise the vehicle using a car lift or jack stands. Make sure the vehicle is securely supported and on level ground.
Locate the jacking points on your vehicle, as indicated in the owner’s manual. Position the jack or car lift at the designated jacking point and raise the vehicle until the wheel is off the ground.
Make sure the vehicle is securely supported by jack stands or a car lift, and never get under the vehicle while it’s supported by a jack alone.
Step 2: Remove the Wheel
With the vehicle raised, you can now remove the wheel to access the brake disc. (See Also: How Hot Do Car Brake Calipers Get? Scorching Truth Revealed)
Use a lug wrench to loosen the lug nuts, but do not remove them yet. Raise the vehicle further if necessary to give you clearance to remove the wheel.
Once the wheel is removed, you can proceed to the next step.
Step 3: Inspect the Brake Disc
With the wheel removed, you can now inspect the brake disc for wear and damage.
Look for the following signs of wear:
- Thinning of the brake disc: A worn-out brake disc will be thinner than a new one.
- Cracks or scoring: A worn-out brake disc may have cracks or scoring on the surface.
- Warpage: A worn-out brake disc may be warped or uneven.
Use a flashlight to illuminate the brake disc and look for any signs of wear or damage.
Step 4: Check the Brake Pad Thickness
While inspecting the brake disc, also check the brake pad thickness.
A worn-out brake pad will be thinner than a new one. Use a brake pad thickness gauge to measure the thickness of the brake pad.
Consult your vehicle’s owner’s manual for the recommended brake pad thickness. (See Also: How Do You Get Air Out Of Brake Lines? Easy Fix)
Step 5: Clean the Brake Disc
Once you have inspected the brake disc and brake pad, clean the brake disc with a brake cleaner.
This will help remove any dirt or debris that may be obscuring your view of the brake disc.
Step 6: Reassemble the Vehicle
With the inspection complete, you can now reassemble the vehicle.
Put the wheel back on and tighten the lug nuts in a star pattern.
Lower the vehicle to the ground and tighten the lug nuts as much as possible in a star pattern.
Conclusion
Checking brake discs is a critical maintenance task that can help ensure the safety and reliability of a vehicle. By following the steps outlined in this guide, you can perform a thorough inspection of your brake discs and identify any signs of wear or damage.
Remember to always consult your vehicle’s owner’s manual for specific instructions on how to check brake discs on your particular vehicle.
