Surface Preparation

Before starting the sanding process, it’s important to ensure that the surface of your calipers is free from any existing paint, rust, or imperfections. If there are any areas with peeling paint or rust, use a wire brush or abrasive pad to remove them.

Once this is done, wipe the calipers down with a clean rag and some brake cleaner to make sure there is no debris left on the surface.

Next, you can start sanding the calipers using either sandpaper or a sanding wheel. Start with a coarse grit (around 80-120) and work your way up to a finer grit (around 220-320). This will help create a smooth surface for the powder coating to adhere to.

Make sure to sand all surfaces evenly and thoroughly – including any crevices or hard-to-reach areas.

Once you have finished sanding, it’s important to clean the calipers again. Use brake cleaner and a lint-free cloth to wipe down all surfaces until they are completely free of dust and debris. This step ensures that the powder coating will adhere properly and gives you a flawless finish.

With these steps complete, your brake calipers are now ready for powder coating!


To protect certain areas from the paint, it’s crucial that high-temperature masking tape or silicone plugs are utilized. These materials can withstand the high temperatures of the powder coating process without melting or degrading.

It’s important to cover any areas that you don’t want to be coated, such as the piston bores and bleeder screw holes. When using masking tape, make sure to apply it tightly and evenly around the area you want to protect. Press down firmly on the edges of the tape to ensure a good seal and prevent any powder from seeping underneath.

For threaded areas, use silicone plugs that fit snugly into the hole. Make sure they are fully inserted so that no powder can get inside. Taking the time to properly mask off these areas will ensure a clean and professional-looking finish on your brake calipers.

By doing so, you’ll have peace of mind knowing that critical components like piston bores and bleeder screw holes won’t be clogged with powder coating material. This gives you more freedom when using your brakes since everything will be working smoothly and efficiently.

Powder Coating Application

When setting up your workspace for applying a powder coating, you’ll need to ensure that proper ventilation is in place to prevent inhalation of any harmful particles. This means having an enclosed and well-ventilated area with an exhaust fan or air filtration system in operation.

You should also wear appropriate personal protective equipment such as a respirator mask, gloves, and safety glasses.

Once you have established the right environment, you can proceed to apply the powder coating onto the brake calipers using a powder coating gun or other equipment. The key here is to achieve an even coat from all angles while avoiding excessive thickness or unevenness.

It’s essential to follow the manufacturer’s instructions regarding the amount of time and pressure required during application.

After completing the application process, transfer your coated calipers into a curing oven or heat source according to the manufacturer’s guidelines. This will allow the powder coating material to melt and fuse together into a smooth, durable surface that resists chipping and fading over time.

With these steps completed successfully, you can now enjoy your newly-powder-coated brake calipers for years to come!


As the heat melts and fuses the coating, a smooth and durable finish is formed on the calipers. This process, known as curing, involves baking the coated calipers in a specialized oven at the temperature and duration recommended by the powder coating manufacturer.

It’s important to follow these guidelines to ensure that your brake calipers receive optimal protection against wear and tear.

During this phase of powder coating brake calipers, it’s critical to allow them time to cool down before handling. Rushing this step can result in damage or even ruin your newly coated calipers.

So once they’ve been cured, take a break and let them cool naturally for an hour or two.

Proper curing is essential for achieving a professional-looking finish on your brake calipers that will last for years. Remember to follow the recommended temperature and duration specified by the powder coating manufacturer, take care not to handle them too soon after baking, and enjoy your new look!

Reassembly and Testing

Now that the coating process is complete, it’s time to put everything back together and test out your newly revamped brakes.

First, reattach the brake caliper piston with a retaining clip or bolt. Make sure it’s securely fastened to prevent any potential hazards while driving.

Next, install new brake pads or replace old ones with freshly coated ones. Ensure they fit into the caliper bracket snugly and that there’s no excess space between the pad and rotor. Tighten all bolts and screws according to manufacturer specifications.

Before hitting the road, test your brakes by doing a few stops at low speeds in a safe area. Listen for any unusual noises or vibrations during braking, as this could indicate an issue with installation or alignment of parts.
