As seen on Two Guys Garage on the SPEED channel: Not all new brake pads sold today include new hardware, but these parts wear down just like your pads do and need to be replaced. The caliper sliders keep the brake pad in place when sitting in the caliper. One tip when you're installing your new hardware. Use CRC SILARAMIC Brake System Grease to protect all moving caliper hardware including backing plates and any mating surfaces. This will prevent rust and oxidation, and the anti-wear additives help protect against brake friction and corrosion. CRC SILARAMIC is made up of a pure silicone dry film lubricant that allows brake parts to move freely under the most aggressive braking situations. You can also use SILARAMIC on high temperature ceramic brakes because it withstands temps up to 3,000 degrees Fahrenheit. Once the brakes are secure, pump the brakes 2 or 3 times and the brakes should feel nice and firm.
