Diagram Ref No 40
Constructed from high-strength, multi-layer reinforced rubber with corrosion-resistant OE-style metal end fittings, the hose is engineered to withstand extreme hydraulic pressures, repeated rear suspension movement, elevated braking temperatures and continuous exposure to moisture, road salt and road debris. Precision-manufactured for direct OE-style installation, it provides a secure, leak-free connection while maintaining the flexibility required for unrestricted suspension travel.
What This Product Does:
- Transfers hydraulic brake fluid to the rear brake caliper.
- Maintains consistent hydraulic braking pressure.
- Allows unrestricted rear suspension movement without stressing the brake line.
- Provides a secure, leak-free hydraulic connection.
- Supports smooth, responsive and reliable braking performance.
- Withstands high operating pressures and braking temperatures.
- Helps maintain balanced rear braking performance.
- Forms an essential part of the vehicle's hydraulic braking system.
Symptoms Of Wear Or Failure:
- Brake fluid leaks around the hose or fittings.
- Soft or spongy brake pedal.
- Cracked, split or perished rubber hose.
- Bulging hose when brake pressure is applied.
- Corroded or damaged metal fittings.
- Reduced rear braking performance.
- Brake warning light caused by low brake fluid.
- Rear brake caliper sticking due to internal hose collapse.
- Uneven rear brake pad wear.
- MOT or vehicle inspection failure due to deteriorated brake hose condition.
Why Replacement Matters:
- Brake hoses are subjected to constant hydraulic pressure, repeated suspension movement, high braking temperatures and continual exposure to moisture, road salt and debris. Over time, the reinforced rubber can deteriorate internally and externally, while corrosion may affect the metal fittings, increasing the risk of leaks, pressure loss or restricted brake fluid flow.
- A failing brake hose can reduce braking performance, create an inconsistent brake pedal feel and, in severe cases, lead to hydraulic brake failure. An internally collapsed hose may also prevent brake fluid from returning correctly, causing the rear brake caliper to bind and accelerating brake pad and brake disc wear.
- Replacing a worn or damaged rear brake caliper hose restores safe, reliable hydraulic pressure and consistent braking performance. The OE Match replacement provides factory-style fitment, premium-quality reinforced construction and long-lasting durability, helping maintain the braking performance, safety and reliability expected from your Porsche.

Coilover brake line support bracket kit. 
Fits:
Porsche 911 - 1965 to 1989
Standard front struts have welded-on brackets to support the brake hard line. Threaded body coilover struts and coilover sleeve conversion require the removal of these brackets, leaving the brake lines unsupported and prone to failure – always at the worst possible time.
- Our support bracket kit is an easy bolt-on support for the brake lines and bolts to existing threaded holes on the strut.
- Easy bolt-on – Attaches to the brake dust shield mounting holes using provided hardware. dust shields can be retained or removed.
- Prevents brake hard line flex / fatigue – Supports the brake hard line. Unsupported, the hard line will constantly flex and eventually leak.
- Quality throughout – Purpose made brackets are laser – cut from stainless steel and pre-formed. Top quality hardware is provided to complete the kit.

Porsche Standard Brake Hoses | Design911 Durable Hydraulic Lines for Reliable Braking Performance
Brake hoses are a critical part of your Porsche’s hydraulic braking system, transferring brake fluid between the master cylinder, calipers, and wheel cylinders. These flexible lines ensure consistent pressure delivery, allowing smooth, precise braking every time you press the pedal. Over time, brake hoses can deteriorate due to heat, pressure, and environmental exposure — leading to leaks, spongy pedal feel, or brake failure. Regular inspection and timely replacement of standard brake hoses are essential for maintaining safe, predictable braking performance.
At Design911, we supply a wide range of standard brake hoses, engineered for durability, flexibility, and perfect fitment. Each hose is manufactured using multi-layer reinforced rubber or synthetic materials designed to handle extreme hydraulic pressures and temperatures. Ideal for servicing, restorations, or brake system maintenance, our hoses deliver reliable performance and compatibility across a wide range of Porsche models.
What Do Brake Hoses Do?
Brake hoses serve as the flexible connection between the vehicle’s rigid brake lines and moving suspension components, maintaining uninterrupted hydraulic pressure during braking.
Core Functions:
• Transfer brake fluid pressure from the master cylinder to the calipers.
• Allow controlled flexibility as the suspension moves.
• Maintain a sealed hydraulic system under pressure.
• Ensure consistent braking force across all wheels.
• Support safety and precision in both daily driving and performance
conditions.
High-quality hoses are vital to ensuring your Porsche’s braking system operates with accuracy, safety, and confidence.
Why Do Brake Hoses Fail or Degrade?
Brake hoses endure constant exposure to pressure, heat, and environmental contaminants, which can cause internal and external damage over time.
Common Causes of Failure Include:
• Cracking or splitting from age and heat exposure.
• Internal swelling or collapse restricting fluid flow.
• Corrosion at the fittings or connections.
• Contamination from degraded brake fluid.
• Physical damage from debris or improper routing.
When hoses deteriorate, symptoms such as a soft brake pedal, uneven braking, or fluid leaks can appear — all signs that immediate replacement is necessary.
Why Replace or Upgrade Your Porsche Standard Brake Hoses?
Replacing worn hoses restores braking integrity and hydraulic efficiency. Design911’s precision-engineered hoses are built to match Porsche’s stringent performance standards, ensuring dependable braking in all driving conditions.
