What this part does
The front brake caliper houses the pistons and brake pads, serving as the primary mechanical component in the front braking system. Mounted directly to the steering knuckle, it converts hydraulic pressure from the brake master cylinder into clamping force, pressing the pads against the brake rotor to decelerate the vehicle. Because this part comes from a vehicle equipped with the M Sport package, it features a specialized multi-piston fixed design optimized for high-performance stopping power and heat dissipation.
When a brake caliper begins to fail, the internal pistons or slide pins typically seize due to corrosion or torn dust boots. A sticking caliper will cause the vehicle to pull to one side during braking, accelerate brake pad wear on the affected side, and generate excessive heat that can warp the brake rotor. A leaking caliper seal will result in a soft brake pedal and loss of hydraulic pressure.

Before you order
This is the right (passenger) side front caliper. It is critical to verify your vehicle's specific brake option codes before ordering. The vehicle it came from was equipped with the M Sport package, meaning this caliper is physically larger and utilizes different brake pads and mounting points compared to the standard base-model 7 Series calipers.
Always inspect your brake flex hoses when replacing a caliper; a collapsed hose can trap hydraulic pressure and mimic the symptoms of a seized caliper piston. We strongly recommend installing new brake pads, inspecting the rotor for minimum thickness, and performing a complete brake fluid flush to remove moisture from the system when installing this replacement.
