Corroded Brake Disc

[stevenkeyte]

Greetings, I was unwell for many days and did not operate my CX 30. We had substantial rainfall. Upon cessation, I saw that all the brake discs of the vehicle were significantly corroded. I understand it is said that driving would remove it, nevertheless thus far, little has been eliminated.Are there any methods or products available for the removal of rust from brake discs? Thank you

I would be quite reluctant to put any substances on my brake rotors. Their operation involves the friction generated between the brake pad material and the revolving steel discs. Any substance you apply would a) be rapidly removed during your next drive (together with any accumulated rust) and b) might adversely affect friction, resulting in less stopping power.

Refrain from applying any surface treatment to the rotors.
Standard braking is unlikely to eliminate rust immediately; many forceful stops should have that effect.
The primary issue is the mobility of the pads; verify that the calliper pins and other components are not corroded and can move freely.

The CX 30 is hardly five months old, therefore I anticipate that the pads and related components remain in satisfactory condition. I see several brake and rust removal goods available.I guess they are not satisfactory? Thank you one again.

Crc brake cleaner.

Indeed, use brake cleaner while replacing pads; nevertheless, refrain from using it for regular cleaning of rotors and pads. The substance is very corrosive, and if applied while the wheels are mounted on the vehicle, it will deteriorate the painted coatings and permanently damage the wheel finish. Furthermore, overspray may adhere to the vehicle's paint, perhaps resulting in complications. Rusted rotors after rainfall is typical and will dissipate with minor brake use during standard driving. To the original poster, you may invest significantly and get zinc-plated rotors for all wheels. Corrosion is unlikely to be an issue with them; nonetheless, you may incur significant financial loss as a result. As I already said, OP, accept it. It is typical and self-resolving with limited driving.

Coated rotors do not prevent corrosion on the brake surface, since the coating is rapidly eroded by standard use immediately after installation. The remainder of the rotor will stay free from rust for a period of time.

Indeed, the natural shedding of surface rust on the mating surfaces, along with rust control measures on non-mating surfaces, would make them seemingly cleaner.
