Caliper PS LH

The Wilwood Caliper PS LH is a left-hand driver-side brake caliper engineered for high-performance and tactical vehicle applications where precision stopping power is non-negotiable. Designed for operators and technicians who demand reliable braking under extreme conditions—from law enforcement pursuit vehicles to military tactical operations—this two-piston aluminum caliper delivers the thermal stability and modulation required in demanding duty cycles. Whether upgrading a patrol unit, tactical transport, or performance platform, this caliper addresses the critical need for dependable, repeatable braking performance.

Constructed from aluminum with a clear anodized finish, the Caliper PS LH features a robust two-piston design that provides balanced hydraulic clamping force across a 9-inch OD rotor with 0.200-inch thickness—a specification common in military and law enforcement brake systems where consistent fade resistance is essential. The 2.500-inch lug mount interface ensures secure, repeatable installation and alignment, critical for maintaining brake bias and responsiveness. The compact footprint of 4.5 x 3.5 x 5.9 inches and lightweight 1.15-pound design minimize unsprung mass while maximizing brake surface area contact, reducing pedal effort and improving stopping consistency under tactical conditions.

This left-hand caliper is ideal for vehicle platforms equipped with Wilwood brake systems or compatible OEM assemblies requiring driver-side replacement or retrofit. Installation requires proper rotor specification matching and brake line integration; technicians should verify 2.500-inch lug compatibility and 0.200-inch rotor thickness before ordering. The clear anodized aluminum finish resists corrosion in field and marine environments, making it suitable for vehicles deployed in harsh climates or high-salt duty areas. Rapid emergency stops, sustained braking during evasive maneuvers, and prolonged mountain descents—all demand the thermal management and durability this caliper delivers.
