This is an unloaded caliper, so brake pads are not included. As a remanufactured original equipment unit, it is rebuilt through a process that reduces the energy and raw material needed to make a new part by 80%.
Signs a caliper may need replacing include the vehicle pulling to one side under braking, fluid seeping near the wheel, uneven pad wear or a dragging brake. Other brake components can cause the same symptoms, so diagnose the cause first. This listing is for the front left position. Replacing both calipers on the same axle together is recommended for even, balanced braking, and the system should be bled after installation.
