Military HMMWV / Humvee Brake Caliper Guide Pin (Single)
Replace a bent, pitted, or seized guide pin with this heavy-duty HMMWV brake caliper slider pin. Sold strictly as a single, standalone component, this pin is ideal for quick repairs when your existing caliper housing, rubber bushings, and sleeves are still in reusable condition.
A seized or corroded slider pin prevents the brake caliper from moving freely, leading to a dragging brake, severe pad wear, and excessive rotor heat. This direct-fit replacement restores smooth, reliable sliding action to your vehicle's inboard braking system.
Part #12342339 / NSN 5305-01-185-8657 is the single most common brake caliper guide/slider pin across the entire HMMWV fleet. It is not limited to early 10-inch brake configurations.
It's standard for all standard hydraulic floating calipers. The primary exceptions across the HMMWV platform are aftermarket/specialized high-performance brake retrofits (such as specific multi-piston fixed-caliper upgrades) or outer hub-mounted performance packages, which use proprietary carrier pins.
Key Features & Specifications:
- Standalone Component: Includes one (1) brake caliper pin only. No boots, sleeves, or extra hardware included.
- Heavy-Duty Construction: Machined from high-strength steel to withstand the extreme heat and stress of tactical vehicle operations.
- Exact Fitment: Replaces the factory guide pin on front or rear inboard disc brake calipers.
- Interchange Numbers: Directly replaces Military Part 12342339, NSN 5305-01-185-8657, and manufacturer numbers 0723312 / 099912-01.
Part #12342339 / NSN 5305-01-185-8657 is the most common brake caliper slider pin across the fleet, it only works for standard 10-inch inboard brake setups found on early and mid-generation variants (like the M998, M1025, and standard M1097).
