The floating caliper design allows for self-alignment during braking, improving pad wear and braking efficiency. Caliper slides are included to ensure smooth movement and proper function, while the gray finish provides corrosion resistance. The bleeder screw thread size is M10 x 1.0, compatible with standard brake bleeding tools.\u003c\/p\u003e\u003ch2\u003eAbout the PowerStop - Rear OE Stock Replacement Caliper Line\u003c\/h2\u003e\u003cp\u003eThe PowerStop - Rear OE Stock Replacement Caliper line focuses on providing direct replacement parts that meet original equipment standards.
