The Backbone of Safe, Balanced Front Braking
Your Tesla Model S (2012-2021) or Model X (2015-2021) relies on precise braking to match its high-performance capabilities—and the 1007794-00-C left-hand front brake caliper is the linchpin of that system. As the “muscle” of your front-left brake, it converts hydraulic pressure into stopping force, clamping down on the rotor to slow or halt your vehicle with the consistency Tesla owners trust.
A failing left-front caliper doesn’t just weaken brakes—it creates dangerous imbalance. If it sticks, leaks, or fails to engage evenly, your Model S/X may pull to the right during stops, lengthen braking distances, or overheat the left rotor. This caliper restores symmetry to your braking system, ensuring every stop feels smooth, controlled, and safe—whether you’re cruising highways or navigating city traffic.
- Turns Pedal Pressure Into Stopping Power: When you press the brake pedal, brake fluid flows into the caliper, pushing its internal pistons outward. These pistons squeeze your brake pads (sold separately) against the left-front rotor, generating friction that slows the wheel—all in under a second.
- Fights Brake Fade: Built with a vented aluminum housing that dissipates heat from friction. This prevents “brake fade” (weakened stopping power from overheating) during long downhill drives or repeated hard stops (e.g., merging in heavy traffic).
- Ensures Even Wear: Precision-machined pistons apply uniform pressure to the brake pads, so your rotor wears evenly (no warping) and your brakes feel smooth, not jerky.
- Stands Up to the Elements: Sealed internals and a corrosion-resistant E-coat protect against rain, road salt, and debris—critical for a component exposed to mud, snow, and highway grime year-round.
Don’t wait for a brake emergency—watch for these red flags:
- Pulling to the Right When Braking: A stuck or slow-engaging left caliper lets the right brake work harder, yanking the steering wheel right.
- Squealing/Grinding Noises: If the caliper’s pistons seize, pads can drag on the rotor, causing metal-on-metal grinding (a sign of urgent damage to both caliper and rotor).
- Overheated Left Rotor: A hot, discolored left-front rotor (compared to the right) means the caliper is sticking, creating constant friction even when you’re not braking.
- Soft or Spongy Brake Pedal: A caliper leak can drain brake fluid, making the pedal feel “mushy” and cutting stopping power—this is a safety hazard.
Cheap aftermarket calipers cut corners on precision and durability—this one is engineered for Model S/X’s weight and performance:
- Tesla-Exact Fit: Machined to match your Model S/X’s front hub and rotor dimensions perfectly. No trimming, shimming, or modification needed—just plug-and-play installation.
- Leak-Proof Seals: High-temperature O-rings (rated to 320°F) prevent fluid leaks, unlike generic calipers that fail in extreme heat (e.g., mountain driving).
- Tested for Tesla’s Demands: Validated through 15,000+ simulated brake cycles, including cold-weather (-25°F) and high-load testing—ensuring it performs in every climate.
- Lightweight Advantage: Aluminum construction reduces unsprung weight, which improves steering response and slightly boosts battery efficiency (less weight to move = more range).
- 1x Left-Hand Front Brake Caliper (1007794-00-C)
- Factory-matched mounting bolts (with pre-applied thread locker)
- Digital Installation Guide: Step-by-step photos, torque specs (108 Nm for caliper-to-steering knuckle bolts; 45 Nm for brake hose bolts), and brake bleeding instructions (critical for removing air from the system).
