What are brake caliper brushes made of?
Content
| Brake caliper brushes are made from a variety of materials, each selected for practical reasons. | ||
Steel | ||
| Steel is a strong alloy created by adding carbon to iron. Some brake caliper brushes come with steel wire bristles that are strong, corrosion resistant and highly abrasive. | |
Stainless steel | ||
 | Stainless steel is made up of iron, nickel and chromium. It is resistant to staining and corrosion and is used for its durability. The wire bristles of some brake caliper brushes are made of stainless steel. | |
Brass | ||
 | Brass - a yellow alloy of copper and zinc - can also be used for wire bristles. It is not as strong as steel and less abrasive, but highly resistant to corrosion. | |
 | When choosing the type of bristle it doesn't really matter how strong the bristle is - it's more a matter of using the right bristles for the right brake area. It is useful to have two brushes with different types of bristles so that they can be used on certain areas of the brake - brass bristles for more delicate areas and steel bristles for strong areas. | |
PVC | ||
 | PVC (polyvinyl chloride) is a very common plastic. It is used for brake caliper brush handles because it is abrasion resistant, lightweight, resistant to breakage when dropped, and has excellent mechanical strength and toughness. Mechanical strength or tensile strength is the amount of force/stress that an object can withstand before breaking. | |
