Flexline Kit 87-93 Mustang

The Flexline Kit 87-93 Mustang by Wilwood is a DOT-approved brake hose assembly engineered for Ford Mustang owners running 1987–1993 model years who demand reliable hydraulic performance. This front-axle brake line kit addresses the core need of any vintage Mustang upgrade: replacing original rubber hoses with modern, fail-resistant braided stainless construction that withstands high-pressure cycling and resists abrasion in tight engine bay environments. Whether you're building a street machine, restoring a performance classic, or upgrading existing brake lines during a caliper swap, this kit delivers the safety and durability professional mechanics and enthusiasts expect.

Built with braided stainless steel construction, the Flexline Kit features an 18-inch main line paired with 3 AN hose sizing and dual 3 AN straight inlet and outlet fittings, ensuring zero-flex hydraulic transmission from master cylinder to calipers. The braided design resists ballooning under heavy braking loads—a critical failure point in aging rubber hoses—while the stainless cover protects against road salt, abrasion, and heat cycling that degrades traditional lines. DOT approval confirms compliance with federal brake safety standards, making this kit street-legal and reliable for both daily driving and track days where brake line integrity is non-negotiable.

Technicians and Mustang enthusiasts benefit most when upgrading to modern brake architecture—pairing this kit with Wilwood calipers, master cylinders, or OEM replacements requires hose routing that the 18-inch length and straight fittings accommodate across third-generation Mustang geometry. Installation demands basic mechanical skill: disconnect the factory line at the wheel end, route the new assembly forward avoiding pinch points, and torque fittings securely. This kit fits exclusively 1987–1993 Mustang front braking systems; verify caliper type and master cylinder layout before ordering to ensure compatibility with your specific brake configuration.
