The caliper brake line is a hydraulic line that delivers brake fluid under high pressure directly into the brake caliper. It’s shaped specifically to fit Porsche calipers, ensuring a secure and leak-free connection.
Functions:
- Transfers brake fluid pressure to the caliper pistons.
- Provides a strong, non-flexing connection for consistent braking.
- Withstands extreme hydraulic pressure without expansion.
- Designed to match OEM routing for proper fit and safety.
Symptoms Of A Faulty Brake Line:
Brake lines can corrode, crack, or get damaged over time.
Warning signs include:
- Brake fluid leaks near the caliper connection.
- Soft or spongy brake pedal caused by fluid loss.
- Reduced or uneven braking performance.
- Pulling to one side when braking.
- Visible rust, cracks, or bends in the metal pipe.
A compromised brake line is a serious safety hazard. If it leaks or fails under pressure, braking efficiency is reduced or lost completely. Replacing it with a genuine OEM Porsche brake line ensures:
- Precise fitment with factory brake calipers and hoses.
- Leak-free, high-pressure performance.
- Corrosion resistance and long service life.
- Restored braking safety and peace of mind.

Ensure optimum braking assist performance on your Porsche with this genuine OEM vacuum line. Designed for 987-series vehicles (Boxster/Cayman 2005-08), this line connects the vacuum source to the brake assist or under-body vacuum system, ensuring proper vacuum supply, consistent brake pedal feel, and reliable operation.
Fits:
- Porsche Boxster 987 2.7L 2005 -08/08
- Porsche Boxster 987 S 3.2/3.4L 2005-08/08
- Porsche Cayman 2.7L 987C 2006-08
- Porsche Cayman S 3.4L 987C 2005-08
Diagram Ref No 14
What This Product Does:
- This vacuum line carries engine or brake-servo vacuum (negative pressure) from the vacuum source (e.g., intake manifold or dedicated vacuum pump) to the brake master cylinder/servo or rear axle vacuum assist components.
- The line ensures that the brake assist system (and possibly other vacuum-dependent systems) receive the correct vacuum pressure so that the driver has proper brake pedal feel, braking power assist, and overall vacuum system integrity.
- A proper vacuum line prevents loss of assist, ensures consistent braking effort, and avoids vacuum leaks that could affect engine operation or brake performance.
Symptoms Of Wear Or When To Replace:
- Reduced brake assist: The brake pedal may feel harder than normal, or the braking response may require more effort — indicating the vacuum feed is compromised.
- Hissing or vacuum leak noise: A damaged or cracked vacuum line may emit a hissing sound under load as vacuum is lost.
- Visible damage, cracking, brittleness, kinks or splits in the hose/line, especially under the vehicle or near mounting points.
- Check engine or brake system warning lights: A vacuum leak may trigger fault codes related to braking or vacuum-supply detection.
- Age-related deterioration: Rubber or plastic vacuum hoses degrade over time (heat, road debris, chemical exposure) and for 987-series vehicles these lines are good candidates for preventive replacement.
- Brake safety & performance: A secure, intact vacuum line is critical to ensuring brake assist works properly — directly impacting stopping distances and driver safety.
- System reliability: A genuine part ensures the correct hose diameter, material and routing — preventing future leaks, vacuum loss and other associated issues.
- Prevents further damage: A failed vacuum line may cause compensatory wear on other brake components (master cylinder, servo) or affect engine vacuum systems — replacing proactively prevents secondary damage.
- OEM fitment: Using the correct Porsche part (#98735557503) keeps the system as engineered and avoids mismatches which could reduce reliability or cause fit/clearance issues.
- Maintains vehicle value & integrity: For Porsche vehicles, even small parts like vacuum lines matter for overall build quality, service history and operational confidence.

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.
