What this part does

The front left brake caliper is a critical hydraulic component that houses the brake pistons and brake pads. Mounted directly to the front driver side steering knuckle, it receives hydraulic pressure from the master cylinder when the brake pedal is depressed. This pressure forces the pistons outward, clamping the brake pads against the brake rotor to generate the friction needed to slow or stop the vehicle.

When this component fails, the internal pistons or slide pins typically seize. A stuck caliper will cause the vehicle to pull sharply to one side during braking, create excessive heat near the wheel, and lead to accelerated, uneven wear on the brake pads and rotor. A leaking internal seal will result in a soft brake pedal and loss of hydraulic pressure.

Before you order

• Verify the 7PP615124 part number against your original unit. Porsche offers multiple braking systems for the Cayenne depending on wheel size, trim level, and whether the vehicle is equipped with standard or carbon-ceramic brakes.
• It is highly recommended to replace brake calipers in pairs across the front axle to maintain balanced hydraulic pressure and prevent pulling during heavy braking.
• Installation requires a complete bleed of the brake hydraulic system to remove introduced air. Ensure you use the manufacturer-specified brake fluid.
• Always verify the position of the bleeder screw upon installation; it must point upward to allow trapped air to escape during bleeding.
