The Arvin 8.28" Left Axial Disc Brake Caliper is the perfect choice for your vehicle's braking system. This caliper features a mounting hole size of M20 X 2.5 and a distance A-B of 3 1/4". for a secure fit. The floating calipers move inward and outward with the wheel rotation, reducing wear on the brake pads and pistons and ensuring optimal braking performance. This caliper offers more even distribution of pressure across the brake pad for a smoother, more efficient braking experience. FleetPride is your First Click in Heavy Duty®.
