Whether you're carrying out routine brake maintenance or a complete restoration, this OE Match brake hose provides factory-style fitment and reliable braking performance.
What Does the Rear Brake Hose Do?
The rear brake hose forms an essential part of the hydraulic braking system, transferring brake fluid from the fixed brake pipe to the moving rear brake assembly.
Its functions include:
- Carrying hydraulic brake fluid under pressure
- Allowing suspension and axle movement
- Maintaining consistent brake pressure
- Providing safe, reliable braking performance
A flexible brake hose is critical to ensuring full braking efficiency while allowing normal suspension travel.
Why Do Brake Hoses Fail?
Brake hoses are exposed to high hydraulic pressures, road dirt, moisture and constant flexing throughout their service life.
Common causes of failure include:
- Age-related rubber deterioration
- Surface cracking and perishing
- Internal hose collapse
- Corrosion around the end fittings
- Damage from road debris
- Contamination from brake fluid or oil
A deteriorated hose can restrict brake fluid flow or develop leaks, affecting braking performance and safety.
When Should They Be Replaced?
Replacement is recommended if the hose shows:
- Cracks or perished rubber
- Fluid leaks
- Corroded end fittings
- Bulging under braking
- Internal restriction causing uneven braking
- Signs of ageing during brake servicing or restoration
As brake hoses naturally deteriorate over time, replacing them as part of a complete brake overhaul is considered good preventative maintenance.
Porsche 356 Brake Hoses & Hydraulic Components
The hydraulic braking system relies on flexible brake hoses to maintain consistent brake pressure while allowing suspension movement. As these hoses age, the rubber gradually hardens and deteriorates, increasing the risk of leaks, restricted fluid flow and reduced braking performance.
Replacing ageing brake hoses is one of the simplest and most effective ways to improve braking reliability and safety. OE Match brake hoses are manufactured to OE specifications, offering dependable performance, factory-style fitment and excellent value for routine servicing or concours restorations.
Benefits of Replacing the Rear Brake Hose
- Restores reliable hydraulic brake pressure
- Improves braking consistency
- Prevents leaks caused by ageing hoses
- Accommodates normal suspension movement
- Ideal during brake system refurbishment
