Diagram Ref No 7
The rear brake hose is a flexible hydraulic connection between the vehicle's rigid brake pipework and the rear brake caliper. When the brake pedal is pressed, hydraulic pressure travels through the braking system and brake hose to the caliper, allowing the caliper pistons to apply the brake pads against the disc.
Unlike rigid brake lines, flexible hoses must accommodate suspension and wheel movement while continuing to contain high hydraulic pressure. This makes their condition particularly important to safe and consistent braking.
Over time, brake hoses can deteriorate through age, heat, contamination, repeated flexing and environmental exposure. The outer covering may crack or perish, fittings can corrode, and internal deterioration can restrict fluid flow even when the hose appears acceptable externally.
Replacing a worn or damaged hose with this OE Match Rear Caliper Brake Hose helps restore secure brake-fluid delivery and dependable rear brake operation.
What This Product Does:
- Carries pressurised brake fluid to the rear brake caliper.
- Provides a flexible connection within the hydraulic braking system.
- Accommodates normal suspension movement.
- Allows movement without relying on rigid brake pipework to flex.
- Helps maintain hydraulic pressure during braking.
- Supports correct rear caliper operation.
- Helps provide consistent brake pedal response.
- Maintains a sealed brake-fluid circuit.
- Connects associated rigid brake lines and caliper components.
- Replaces a cracked, leaking, restricted or deteriorated brake hose.
- Supports safe and predictable braking performance.
- Provides an OE Match replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Visible cracks in the hose.
- Perished or deteriorated outer rubber.
- Bulging or swelling.
- Brake fluid leaking from the hose.
- Wetness around hose fittings.
- Corroded end fittings.
- Damaged hose connections.
- Abrasion or chafing.
- Brake hose twisted or incorrectly routed.
- Soft or spongy brake pedal.
- Increased brake pedal travel.
- Vehicle pulling under braking.
- Uneven braking performance.
- One rear brake dragging.
- Rear brake slow to release.
- Excessive heat from one brake.
- Uneven brake pad wear.
- Brake-fluid reservoir level dropping.
- Brake warning light.
Why Replacement Matters:
- The brake hose must safely contain the hydraulic pressure generated whenever the brakes are applied.
- If a deteriorated hose begins leaking, hydraulic pressure and brake fluid can be lost. This may reduce braking performance and potentially compromise the affected hydraulic circuit.
- Replacing a deteriorated hose before complete failure is essential for maintaining a dependable braking system.

DOT 4
Having an extremely high boiling point and lower viscosity than required, it meets and greatly exceeds regulatory standards. Also suitable for vehicles with ABS.
Vapour Lock formation
This sort of habit leaves room for the Vapour Lock, the formation of vapour bubbles due to boiling of the brake fluid that replace the normal fluid and are compressed, thereby sending the brake pedal to its fill stoke (spongy pedal). The origin is incident in the porosity of the tubes that make up the braking circuit, which in time draw moisture into the fluid, drastically reducing the boiling point. The result is a reduced braking efficiency.
Brembo Premium Brake Fluid
Brembo Premium brake fluids have a higher boiling point that exceeds the standard, thus offering superior resistance to the Vapour Lock and ensuring braking efficiency even at low temperatures. With high anti-corrosion properties and resistance to oxidation, Brembo brake fluid also allows for long-term unaltered chemical/physical characteristics of the fluid in operating circuit; therefore, preserving its integrity.

Brake fluid is one of the most important fluids in a car as without it, stopping the vehicle safely would be impossible. The Brake fluid transmits the force exerted by the driver on the brake pedal onto the wheel brake.
To ensure perfect operation of the brakes, the brake fluid must be changed regularly during inspection or maintenance and tested with the correct brake fluid tester.
Brake fluid should be changed every two years.
The higher the DOT class, the higher the boiling temperature and wet boiling point. Higher DOT classes tend to allow longer maintenance intervals. The DOT standards are based on the American FMVSS-116 standard of the Department of Transportation (DOT).
Boiling Point and Viscosity
Dry Boiling Point - describes the property of the sealed new brake fluid. In this state, the brake fluid is almost anhydrous (substance containing no water). The dry boiling point is usually between 240 and 280°C.
Wet Boiling Point - determines the property of the brake fluid at the end of its life cycle, at a water content of 3.5% the fluid should be replaced. This defined wet boiling point must not be undercut.
Viscosity - describes the flow rate of the brake fluid. The lower the viscosity, the faster the brake fluid flows through the brake system, and the faster the brake signals are transmitted.
Important Notes
• Brake fluid is poisonous and a hazardous waste.
• Be careful when changing. The fluid weakens paints and plastics.
• It must not come into contact with eyes or skin. Always rinse spilled liquid with water.
• Do not pour the liquid into drinking water or mix with used oil.
• The colour of the brake fluid reveals nothing about its quality.
• Brake fluid should be stored in its original packaging and in a dry, cool and well-ventilated place.
