Last week, we Powder Coated Brembo Calipers for a customer. The customer purchased brand new calipers for his 2015 Lexus GS350. Since these were brand new in the box, there was little prep we had to do. We outgassed the machining oils by baking the calipers for a short time in our powder coating oven. After the calipers cooled off, we prepped them with solvent, masked off the critical areas and plugged all the threaded holes. To mask and plug the holes, we use a high temp silicone tape and plug that will withstand the temperature of our oven. The makes for an easy and trouble free installation for our customers.
After the prep is done, we powder coat the calipers, 2 coats of super durable wet red and 2 coats of clear coat. This will ensure the maximum amount of protection against road debris, discoloration and durability. As you can see, the finish turned out flawlessly.
Questions We Have Asked
Many people ask, “Why don’t you seperate the calipers (if they are 2 piece) or remove the pistons? The answer is many reasons:
First, you don’t want to separate the calipers. We’ve encountered customers who tried this and they will never seal again. This is because the caliper may slightly become disfigured from relieving stress and the torque to reassemble them. Also, the heat when baking does not help in this scenario.
Second, the pistons will heat up at the same rate of the caliper housing. This will protect against any media or powder getting into the brake cylinders. On used calipers, we have to media blast the brake dust off the calipers. We do not want to get meida inside the cylinder, which could affect braking performance.
Third, the dust seals. This will not affected by temperature change. Furthermore, the seals stay perfectly sealed and are make to take the temperature of high performance braking temperatures.
Lastly, Powder Coated Brembo Calipers is much easier for us as there is less to mask and prep.
Before & After
We can coat used brake calipers, however the process requires more prep. We have to heavily outgas the caliper to get all the brake fluid out of the caliper. The powder coat will be destroyed if any brake fluid gets on it during the curing process. We also have to remove `100% of the old brake dust. Brake dust is non conductive and the powder will not stick to it. If the calipers are on the vehicle, we charge more to remove, prep, coat and reinstall them. They also need bleed so essentially, if they are already on the car, it’s sometimes better to paint them. You can see this process by clicking here.
