Caliper brake line for the front axle on selected Porsche 996 and 997 models without ceramic brakes.
What This Product Does This rigid caliper brake line links the flexible brake hose to the front brake caliper, providing a solid hydraulic path for brake fluid pressure. It helps maintain consistent fluid transfer to the caliper so the braking system can operate as intended.
Functions
- Connects the front brake hose to the caliper body
- Transfers pressurised brake fluid to the caliper
- Helps maintain stable hydraulic pressure at the wheel
- Supports correct caliper positioning relative to the hose
Symptoms of Fault
- Visible corrosion on the brake line or fittings
- Fluid seepage or wetness around the line unions
- Damaged, kinked or crushed metal section near the caliper
- Spongy brake pedal or uneven braking if fluid loss occurs
Why Replacement Matters
Front caliper brake lines are exposed to heat, moisture and road debris, so they can corrode or become damaged over time. Replacing worn or corroded lines helps prevent fluid leaks, supports consistent hydraulic pressure at the caliper and maintains predictable braking response, especially on older 996 and 997 models. OE-equivalent hardware is typically chosen to match original routing and connections.
