Buy Caliper Housing Pin / Bolt (5253000)

The Caliper Housing Pin / Bolt (5253000) is a crucial fastening component used in disc brake systems

across a wide range of Jeep vehicles, including the Wrangler (YJ and TJ), Cherokee (XJ), Grand Cherokee

(ZJ/WK), Commander (XK), and Liberty (KJ). Manufactured as an OEM part by Mopar and widely reproduced

by aftermarket brands such ashCrown Automotive, this hpin or bolt ensures proper alignment and secure mounting of the brake caliper assembly.

The primary function of the 5253000 caliper housing pin is to hold the brake caliper in position while

allowing it to slide smoothly during braking. In a disc brake system, the caliper must move slightly to apply even

pressure on both sides of the brake rotor. This pin acts as a guide and pivot point, enabling that movement while

keeping the caliper firmly attached to the mounting bracket. Without this component, the caliper would not operate correctly, leading to uneven brake pad wear or compromised braking performance. (Mopar Parts Giant)

Physically, the caliper housing pin is a steel bolt with a threaded design, typically measuring M8 x 1.25 x

65 mm.  It is engineered for strength and durability, as it must withstand constant mechanical stress, vibration,

and exposure to heat generated during braking. The bolt is usually zinc-coated or treated to resist corrosion, ensuring long-term reliability even in harsh driving conditions.

This part is designed as a direct-fit replacement

This part is designed as a direct-fit replacement, meaning it matches the original factory specifications for

easy installation. It is typically sold individually, and depending on the vehicle, multiple pins may be required per

caliper assembly. The pin may also be referred to as a caliper guide pin, slide pin, or caliper bolt, reflecting its role in guiding caliper movement.

Compatibility for the 5253000 part number is extensive, covering Jeep models from 1987 through 2010,

including both front and rear disc brake applications depending on the vehicle configuration.  This broad

compatibility makes it a commonly used service part in brake maintenance and repairs.

Over time, caliper pins can wear out, corrode, or seize due to lack of lubrication or exposure to dirt and moisture. Common symptoms of a failing pin include uneven brake pad wear, sticking brakes, pulling to one side, or abnormal noises during braking. Regular inspection and proper lubrication during brake service are essential to ensure smooth caliper operation.

In summary, the Caliper Housing Pin / Bolt (5253000) is a small yet vital component that maintains caliper alignment, supports smooth braking action, and contributes significantly to overall brake system performance and safety.
