How to take care of various finishes on the calipers, rotors and rotor hats,
Baer supplied calipers can come in a variety of finishes including powder coat, anodized and Electroless Nickel. We use what are basically Hybrid powders for our calipers, straight Epoxies have better chip and chemical resistance and Polyesters have somewhat better UV resistance. Hybrids are good at both since calipers do see brake fluid, wrenches, sunlight, etc.
Care of powder: While powder is better than typical wet coatings it is not indestructible as many believe but will provide years of service if properly taken care of. We suggest using mild soap and water only such as car washing product from Mothers, Meguiars, etc. We do not recommend wheel cleaners, while some do not contain acids many do and will stain or even lift the finish. Once a year or more it's a good idea to remove the wheels and completely clean the calipers to remove all brake dust, road grime, etc. this is also a good time to clean the inside of the wheels that is hard to get to otherwise. The dust from the brake pads that are sent with our systems is quite benign and should pose no problem for the finishes, some of the more aggressive pads that may be used for Track days or other events though may harm the finish if left on or the dust gets wet and dries, we strongly recommend when switching back to street pads after an event that the calipers and hats be cleaned at that time.
When bleeding the brakes there will be residual brake fluid left in the bleeder, when driving this will migrate out around the threads and can harm the finish. We recommend using the supplied syringe (or this can be obtained from Baer) to thoroughly flush the bleeder and then using compressed air to dry it out before installing the rubber cap. DO NOT use air to blow out the fluid as it will spray and possibly get in your eyes or harm the paint on the car.
Small scratches can be removed the same way you would on the cars paint by using very fine sand paper and then buffing/polishing the surface, the powder can also be waxed like paint which will make cleaning easier.
Care of Nickel: Electroless Nickel is a very durable finish that does not require much maintenance other than cleaning with mild soap and water. We also do not recommend wheel cleaners for Nickel since they can stain the finish. If the finish does become stained or tarnished use a good (Mothers, Meguiars, etc) metal polish to restore the finish.
Care of Anodize: Whether the calipers are clear anodized or Hard Coated they easily maintained by cleaning with soap and water, Hard Coat calipers used in competition can be cleaned with Scotch Brite to remove baked on grime and pad residue.
The hats are Anodized, some wheel cleaners will spot or stain the color/dye in the finish, the Anodizing is still there but the color is damaged. We recommend using mild soap and water just like the calipers to clean them.
The rotors are Zinc plated, this does make them corrosion "resistant" but they are still Iron and will do as Iron does. The same wheel cleaners that are mentioned above will also stain the Zinc. Vehicles that are used in snowy/salt or other harsh environments will also benefit from keeping them cleaned.
