ABS Brake Line.
Restore the integrity of your brake hydraulics with this genuine OEM rigid brake line for the Porsche 911 (996 Carrera/Carrera 4) models. This high-quality rigid steel line forms part of the front section brake-line circuit (often associated with the ABS/ modulator unit) and ensures optimal brake fluid delivery, pressure stability and system reliability.

Fits:
  • Porsche 996 C2 3.4L 1999
  • Porsche 996 C4 3.4L 1999

Diagram Ref No 6

What This Product Does:

  • This brake line carries hydraulic brake fluid under high pressure from the brake master cylinder or hydraulic/ABS unit to the front brakes (or to the relevant section identified) in the braking system.
  • Because it is a rigid line (usually steel or lacquered steel), it provides a fixed, stable conduit for fluid, resists expansion and maintains proper pedal feel and brake response.
  • In an ABS-equipped system, having correct brake line integrity is vital for the anti-lock system to sense and modulate pressure correctly. A damaged or corroded line can compromise braking or ABS functionality.

Symptoms & Signs Of Wear Or Failure:
  • Visible damage or corrosion: Rusted, pitted or flared ends, cracks in the line or flaking coating that indicate structural weakness.
  • Brake fluid leak: Any sign of fluid seepage, drips, dampness along the underside or around fittings — a failing rigid line can leak at the flare or crack.
  • Soft brake pedal or spongy feel: While harder to detect with a rigid line, if that section is compromised or has internal blockage, pedal feel may degrade.
  • ABS warning or braking inconsistency: If the ABS unit is unable to regulate pressure or if one circuit is compromised, you may see warning lights or uneven braking.
  • During restoration or braking system overhaul: If other parts are being replaced (ABS unit, calipers, fluid), it’s good practice to replace brake lines that look old or suspect, especially for critical parts like rigid front lines.

Why Replacement Matters:
  • Safety & braking performance: The braking system is one of the most critical safety systems in the vehicle. A deteriorated brake line compromises braking response and could lead to failure.
  • Brake pedal feel and response reliability: A properly installed, intact brake line ensures consistent pedal pressure and predictable braking — essential for the driver’s control.
  • ABS & system integrity: In a system with ABS and hydraulic modulator units, all lines must be within specification for proper functioning. A damaged line in this circuit may compromise the system.

About Caliper and Brake Lines

Porsche Calipers & Brake Lines | Design911 Precision Components for Hydraulic Pressure, Control & Performance

Calipers and brake lines are critical elements of your Porsche’s braking system, working together to deliver consistent hydraulic pressure and stopping power. The caliper converts fluid pressure into mechanical force, pressing the brake pads against the disc, while the brake lines ensure precise fluid transfer throughout the system. Maintaining these components in top condition is essential for safety, braking balance, and pedal feel — especially in high-performance or demanding driving environments.

At Design911, we offer a premium range of brake calipers and lines, designed for precision fitment, strength, and reliability. Each component is crafted using corrosion-resistant materials and advanced engineering to deliver consistent hydraulic response, heat resistance, and long-term durability. Whether for road use, restoration, or motorsport applications, our products ensure your Porsche’s braking system performs at its absolute best.

What Do Calipers & Brake Lines Do?

Brake calipers and lines form the hydraulic backbone of the braking system, converting pedal force into controlled, powerful deceleration.

Core Functions:
• Calipers apply clamping force to the brake pads against the discs.
• Brake lines transfer pressurised fluid from the master cylinder to the calipers.
• Ensure consistent pressure and braking balance across all wheels.
• Support heat dissipation and smooth hydraulic operation.
• Maintain precise pedal feel for confident braking control.

Together, these components ensure your Porsche’s brakes deliver the precision, power, and stability required for road and track use alike.

Why Do Calipers & Brake Lines Fail or Degrade?

Both components are exposed to extreme heat, pressure, and environmental elements — conditions that can lead to wear, corrosion, and eventual failure.

Common Causes of Failure Include:
• Corrosion or rust on calipers and fittings.
• Leaking hydraulic seals or damaged pistons.
• Cracked or bulging rubber brake hoses.
• Air or moisture contamination in the hydraulic system.
• Brake fluid degradation causing internal corrosion.
• Physical damage from debris, impact, or improper installation.

When calipers or brake lines fail, braking performance becomes inconsistent or unsafe — with symptoms like spongy pedals, fluid leaks, or uneven braking response.

Why Replace or Upgrade Your Porsche Calipers & Brake Lines?

Replacing worn or corroded components ensures your braking system operates safely and efficiently. Upgrading to high-performance or stainless-steel brake lines enhances pressure consistency and pedal feel, while refurbished or precision-engineered calipers restore perfect hydraulic control.

Key Benefits:
• Restores full hydraulic braking performance.
• Improves pedal responsiveness and feel.
• Eliminates leaks, corrosion, and pressure loss.
• Enhances braking stability under high temperatures.
• Available in performance and standard replacement options.
• Suitable for classic and modern Porsche models.

Design911’s Porsche calipers and brake lines deliver uncompromising reliability and precision — ensuring your Porsche stops with the same confidence it accelerates.

Highlights

• High-quality Porsche brake calipers and hydraulic lines.
• Engineered for performance, durability, and exact fitment.
• Stainless-steel braided options for improved pressure stability.
• Corrosion- and heat-resistant construction.
• Perfect for road, race, and restoration applications.
• Compatible with a wide range of Porsche models.
