Caliper Bracket Spacer Pacer

The ARGO Manufacturing Caliper Bracket Spacer Pacer (ARGAU929-1) is a precision steel brake caliper spacer engineered for Argo AMC Pacer spindle systems. This metric-spec component measures 0.438 inches inner diameter with a 1 inch outer diameter and 0.250 inch thickness, providing exact caliper positioning and brake pad clearance on tactical and law enforcement patrol vehicles. The natural steel construction delivers the durability required for high-heat braking applications in field operations.

Caliper spacers are critical wear items in brake systems designed to maintain consistent pad-to-rotor spacing under repeated heavy braking cycles. The tight dimensional tolerance of this spacer—0.250 inch thickness—ensures repeatable brake modulation and prevents caliper creep that can degrade braking response during high-demand scenarios. Steel construction resists thermal stress and maintains dimensional stability even under sustained heat exposure common to pursuit driving or extended patrol duty. Proper spacer fitment is non-negotiable for brake system reliability and operator safety.

This spacer is purpose-built for Argo AMC Pacer spindle applications, making it the correct replacement for vehicles running that platform. Law enforcement technicians, fleet maintenance personnel, and operators performing brake work on Pacer-equipped rigs will recognize the precision fit required in caliper hardware. The individual unit format allows targeted replacement without requiring full brake assembly overhauls, reducing downtime and cost in field maintenance scenarios.

At 0.09 lbs and compact dimensions (2.45 x 0.3 x 2.7 inches), this spacer is lightweight yet structurally rigid—essential for brake hardware that absorbs kinetic energy under deceleration forces. Sourcing OEM-correct spacers from trusted manufacturers like ARGO ensures brake system integrity across your fleet maintenance program.
