Rear Brake Caliper Without Pads - Left Hand - Base for Tesla Model S/X (2012-2021) | 1007888-00-B

Why This Caliper Matters for Your Model S/X

What It Actually Does (Simple, No Tech Jargon)

• Adds Rear-End Stopping Power: When you press the brake pedal, brake fluid flows into the caliper, pushing its pistons outward. These pistons squeeze your rear brake pads (sold separately) against the left-rear rotor, generating friction that slows the wheel—critical for balancing front brake force and preventing rear-end “lift” during hard stops.
• Prevents Overheating: Built with a vented aluminum housing that dissipates heat from friction. This stops “brake fade” (weakened stopping power) during long drives (e.g., highway commutes) or repeated stops (e.g., stop-and-go traffic).
• Protects Rotors & Tires: Precision-machined pistons apply uniform pressure to the pads, so your rotor wears evenly (no warping) and your rear tires stay aligned—avoiding premature tire replacement.
• Fights Rust & Debris: Sealed internals and a corrosion-resistant E-coat shield against road salt, rain, and mud. Unlike cheap calipers that rust shut in snowy climates, this one stays functional year-round.

Signs Your Rear-Left Caliper Needs Replacement

• Pulling to the Right When Braking: The rear-left caliper isn’t engaging, so the rear-right brake overworks, yanking the vehicle right.
• Grinding/Squeaking from the Rear: Seized pistons cause pads to drag on the rotor, creating metal-on-metal noise (this damages both caliper and rotor—fix immediately).
• Uneven Rear Tire Wear: Bald spots on the inner edge of the left-rear tire (a sign of misalignment from a faulty caliper).
• Soft Brake Pedal: A leak in the caliper drains brake fluid, making the pedal feel “spongy” and reducing overall stopping power—this is a safety hazard.

Built to Tesla’s Rigorous Standards

Why It Outperforms Aftermarket Calipers

• Perfect Fit, No Mods: Machined to match your Model S/X’s rear hub and rotor exactly. No trimming, drilling, or shimming—just bolt it on and connect the brake hose.
• Leak-Proof Seals: High-temperature O-rings (rated to 300°F) prevent fluid leaks, unlike cheap calipers that fail in extreme heat (e.g., summer highway drives).
• Tested for Tesla’s Limits: Validated through 12,000+ brake cycles (including cold-weather -20°F and heavy-load stops) to ensure reliability.
• Lightweight Advantage: Aluminum construction cuts unsprung weight, which improves rear suspension response and slightly boosts range (less weight = less energy used).
