How to Inspect Disk Brakes

Brakes are one of the most important systems on your vehicle. You can build the fastest car you want but if the brakes dont work you will only go that fast once. Here is how to inspect your brakes for problems and safety concerns.

Supplies

Jack, safety stand, correctly sized socket for your wheel lug nuts, inspection light, owners manual or service information.

Step 1: Brake Pedal Feel

Drive your vehicle while paying close attention to how your brake feels. Soft pedal indicates leaks, low fluid, or air in system. Pedal bumping back at your foot and a uneven slowing indicates warped rotors. Listen for sounds as well.

Step 2: Fluid Level and Leak Check

Check your fluid level. Consult owners manual for information on this regarding your exact make and model. Look for leaks as well.

Step 3: Lift and Secure Vehicle

Consult owners manual or service information for information on safely jacking vehicle and proper lifting points. Make sure your lifting equipment meets the standards required to lift your vehicle safely.

Step 4: Remove Wheel to Gain Access to Brake Components

Remove your wheel. If you do not have an impact wrench you will need to break the lugs loose with the wheel on the ground. Make sure you use the correct sized socket so the lugs are not damaged.

Step 5: Inspect Bake Components for Each Wheel

Inspect for worn out pads. Look for grooves worn into the rotor. Check caliper for rattle or looseness. Check pads for looseness or rattle. Look for leaks at the caliper and line.

Step 6: Reinstall Wheel After Inspection and Repairs

After inspecting the brakes for each wheel make sure all the lugs are tightened to the manufacturer specification or if a torque wrench is not available that the lugs are hand tightened enough that they will not come loose. Recheck lug tightness after 50 and 250 miles if a torque wrench was not available.
