Buy Caliper Slipper (5093394AB)

The Caliper Slipper (5093394AB) is a small but essential component in the rear disc

brake assembly of various Jeep vehicles, most hcommonly found on Jeep Liberty (KJ)

models equipped with rear disc brakes. Sometimes hreferred to as a caliper slide shoe,

guide shoe, or parking brake slipper, this part sits between the rear caliper and the

vehicle’s mounting bracket or rotor hat and plays a crucial role in ensuring smooth pad movement during braking.

Unlike the primary brake pads, the caliper slipper does not produce friction against the rotor.

Instead, it serves as a wear surface and alignment guide that helps reduce friction

between the caliper body and surrounding metal components. This part assists the caliper in

maintaining correct alignment relative to the rotor as the pads engage and retract. It also

supports uniform pad wear by helping the caliper apply even pressure across the entire pad surface.

The 5093394AB calibration is manufactured to OEM specifications, designed to directly

replace the original part without modification. Correct fitment is especially important because

a slipper that is too loose can allow excessive caliper play, leading to noise or uneven pad

wear. Conversely, a slipper that is too tight can bind the caliper, restricting pad movement

and reducing braking effectiveness. The part is typically constructed from durable, heat‑resistant materials such as hardened steel or sintered metal, chosen for strength and

resistance to wear, corrosion, and high temperatures.

Installation of the caliper slipper usually occurs during

Installation of the caliper slipper usually occurs during rear brake servicing or caliper

rebuilds. It is located where the caliper body contacts the bracket or hat, and it is installed

along with other brake hardware such as pins, boots, and anti‑rattle clips. During installation,

it’s critical to ensure the slipper is oriented correctly and that mating surfaces are clean and

free of corrosion. Sufficient lubrication with high‑temperature brake grease helps prevent noise and ensures free movement over time.

Signs that a caliper slipper may need replacement include brake noise such as squeaking

or grinding, uneven pad wear, vibration under braking, or a dragging sensation

when the brake is released. If ignored, worn slippers can contribute to premature pad and rotor wear or uneven braking.

In summary, the Caliper Slipper (5093394AB) is a vital supporting component that

ensures proper caliper movement, promotes even brake pad wear, reduces noise, and helps

maintain consistent braking performance in rear disc brake systems. Including this part in routine brake maintenance helps extend the life of core braking components and ensures reliable stopping power.
