Caliper Pistons

OSK Brake Caliper Pistons are typically hard-chromed steel, though some manufacturers use aluminum alloys or phenolic pistons. It is important to remember that the piston surface seals the brake caliper, so the piston should be in like-new condition. The piston should be replaced if it is pitted or scored. Steel Pistons are great for heavy-duty, medium-duty, and passenger vehicles because of their increased durability and ability to endure high compression pressures and operating temperatures. Aluminum Pistons are light-weight and becoming increasingly popular. They are made to suit all kinds of automotive brake systems and also provide a lighter and more cost-effective solution for passenger vehicles.
