Step1Select the color of spray paint for your brake calipers. Remember that some types of spray paint are more suited for metal application than others. If you are confused, consult an employee at your hardware store about the effectiveness of the paints and how much paint you will need.
Step2Loosen the lug nuts holding the tire to the wheel one or two turns. You will need to remove the tire in order to access the brake calipers.
Step3Raise the vehicle off the ground. Since you will only be painting one brake caliper at a time, a car jack may be used, but it is not recommended. If you do use a car jack, make sure you know how secure it is and exercise caution when placing a hand under the car.
Step4Unscrew the lug nuts the rest of the way, then remove the tire from the axle. Make sure that the lug nuts are located in a safe area to prevent loss.
Step5Prepare the brake caliper for painting by scouring it with the wire brush and then by rubbing it with a rag and cleaning solution. How clean the brake caliper is will determine the effectiveness of the paint job.
Step6Locate the bolts holding the brake caliper to its support. Loosen and remove the bolts using the ratchet.
Step7Remove the brake caliper from its support and then clean it again, checking for any areas you may have missed the first time.
Step8Avoid stressing the brake line at all costs. Setting the brake caliper on the rotor is the easiest solution. However, it can prove to be problematic when finally painting the brake caliper. A better solution is to use a coat hanger to suspend the caliper in the wheel well.
Step9Apply newspaper and masking tape to the area surrounding the brake caliper. While there is no one right method as to how to mask the area, make sure that the adhesive on the masking tape will not affect any areas to which it is stuck.
Step10Paint the brake caliper using the spray paint in the color of your choice. Allow time for the paint to dry and then spray on a second coat. A third coat of paint is not necessary, but it is recommended.
Step11Reattach the brake caliper to the support after the paint has dried. Then replace the wheel on the vehicle and lower the vehicle to the ground.
