Another factor that could be playing a part in your rust issue is that your brake pads must match the size of your brakes and rotor or the necessary contact with the brake pads that brushes off the rust build-ups will not occur. The surface of the rotor should be smooth so it can have full contact with the brake pads.
Brake pads must be the exact size to perfectly match the rotor. The more contact the brake pad has with the rotor, the more braking power your vehicle will have.
It is very easy to remove rust from your brake discs, but if the problem is more severe, you will need to take your vehicle into your local automotive dealer or mechanic for a replacement. To reiterate, a bit of rust is normal and will not damage your car or impact your driving abilities. However, over time pitting can occur, and it might simply be time for a replacement around 50, miles. If the rusting or squeaky brakes seem severe or due for an adjustment, take your vehicle in to a professional for an inspection.
Over time, without proper maintenance, regular driving, and properly-fitting brake pads — yes, it can become dangerous. However, most of the time, regular driving prevents the rusting from reaching the point of being hazardous. If you do not properly maintain your car or take it into a body shop once the rust begins to worsen, the risks you face are:.
Again, it takes a variety of factors to cause brake discs to rust excessively, and you will have plenty of warning signs to fix your brakes before they become dangerous. With regular maintenance, expectations, and turning and brake flushes, your brakes will run smoothly and make you feel safe.
If you have any questions or are concerned about a worsening rust issue, take your vehicle into your local mechanic, body shop, or dealership if it is still under warranty. I'm Arwood, but the grandkids call me Big Papa.
They act as the piping for the brake system and are responsible for transporting fluid from the master cylinder to the wheels. Over time, your brake calipers become worn down looking and can be an eyesore on a nicer vehicle. There is not always a need to replace the calipers, but you do not want to drive around with this Lower quality rotors often will rust faster because of the lower quality of the iron used in their manufacture.
Rust will propagate faster in areas where it already is established. If the rotor is severely pitted, then rust will establish itself deep in the pits where the braking action cannot rub it off. The rust will then tend to grow out quickly from these areas. What Causes Brake Rotors to Rust?
Rotor Material Different qualities of brake rotors are available. The rate at which rotors wear depends on several things:. Type of brake pads on the vehicle. Hardness and quality of the castings.
How efficiently the rotors cool themselves. How the vehicle is driven. Braking style of the driver aggressive or easy. Rotors can sometimes be resurfaced, depending on the amount of wear.
When rotors are resurfaced, a mechanic grinds down the surface of the rotors and makes them smooth and flat again. This will only work if the rotors are not warped or cracked. Here are some other factors considered when deciding to resurface, rather than replace rotors:. Rotor Thickness - Original equipment rotors used to be made with enough thickness to go two or more brake pad replacements.
However, some cars being made now use thinner rotors to save weight and cost. Consequently, the rotors may be worn down to minimum thickness specifications which is usually marked on the casting itself by the time the first set of brake pads need to be replaced.
The minimum thickness specification is an important factor because it is the minimum thickness that provides safe braking. As a rotor wears and becomes thinner, it has less mass.
