This task can be done in a few hours and with minimal expense or skill.

To complete this task you will need a few things, below is a suggested list of items, these are not mandatory but they will certainly help mak elife easier when attempting this task:

• A Car Jack
• Two Jack Stands
• Paint
• Paint Brush
• Wire Brush

When painting the calipers, there really is not too much that can go wrong if you take your time and prepare for the task at hand.

There are many aftermarket brands of brake caliper paint and kits that will cost a lot of money but if on a budget or you just have a limited selection at your neighborhood auto parts or hardware store try and find Japlac High Gloss Laquer.

Stick to Jet Black for the color as it will be the easiest to stay clean looking and can easily enhance any color wheel or car its applied to.

Using a paint with a good glossy finish will ensure that you don't see any brush lines as the paint will set to a smooth finish.

Before beginning to dismount any tire place the parking brake in the on position depending on how your vehicle is set up.

Safely jack up the vehicle. 

If starting on the front axle be sure to place an object behind each of the rear tires to avoid any possibility of the vehicle rolling backward and vica versa for the front if beginning on the rear axle.

Remove the first wheel and make sure the car is supported by an axle stand.

This will help you avoid being crushed to death and the vehicle falling off the jack and damaging the brake rotors!

Most likely your calipers are dirty and it would be a very good idea to begin by cleaning each caliper with a wire brush to remove any brake dust, dirt or corrosion which has made a home for itself there.

There is no need to primer the surface so once you have the caliper cleaned and dry you can begin to paint them.

Usually a single coat of paint will be sufficient but for a finish that will last from the elements and miles a second coat is a great idea and should help last for years.

It is easiest to apply the paint using a 1/2" or smaller paint brush

You want a brush that is big enough so not to make this an all weekend project but also small enough that you are able to control where you want to apply the paint and get all the nooks and crannies.

Make sure to keep any paint away from the brake pads.

Avoid any place where the pads sit as well as you do not want to restrict the pads movement. 

You can if you wish apply paint to the shields on the front axle calipers and also to the spring tensioners too.

Be sure as you get to a finishing point that you have applied a nice even finish.

You can begin on the other side of the axle while this side is drying.

Once both sides are done go back to the first caliper and place a second coat lightly over the dry surface for good measure and repeat this step for the other side too.

When this is completed to your satisfaction you can begin to remount the wheel while the paint is still drying.

Be sure to leave the car sitting for a few hours though while the paint completely drys and has fully hardened.

Before doing this I would take a moment and clean the wheels completely front and back as it is not often that most back sides of the wheels are cleaned and it will help to make your newly painted calipers look there best when finished and between car washes.

Now that that is all done remount your wheels and tires and begin with the same proceedure for the other axle.

When both axles have been done lower down the vehicle and step back a few paces and admire your hard work.

Now, go cruise your ride around and look for all the people starring at your car trying to figureout where you got the money for new wheels and brakes
