If your 2022+ Tesla Model 3 or Model Y’s right rear brake caliper is leaking hydraulic fluid, sticking (causing the rear-right brake to drag), or failing to deliver consistent stopping force—this CFN right-hand rear base brake caliper is the safety-critical replacement to restore reliable braking. As an engineered alternative (not Tesla OEM), it’s precision-built to match the 2022+ Model 3/Y’s original caliper specifications: from piston size and hydraulic pressure tolerance to mounting hole alignment, ensuring seamless integration with your vehicle’s brake system and adherence to Tesla’s performance standards.
Brake calipers are the core of your Tesla’s braking mechanism: when you press the brake pedal, the caliper’s piston extends to clamp brake pads against the rear rotor, converting hydraulic pressure into friction that slows the wheel. This CFN base caliper is tailored for the 2022+ Model 3/Y’s rear-right wheel, featuring a single-piston design (matching the factory’s base-trim setup) that ensures balanced braking—no uneven pad wear or “pulling” to one side during stops. Unlike generic calipers that may misalign with Tesla’s brake hoses or mounting brackets, this one fits the original hardware perfectly: the brake hose fitting matches the factory thread size, and the mounting flange aligns with the rear knuckle’s pre-drilled holes, eliminating leaks or piston misalignment risks.
Durability is engineered for the harsh conditions rear calipers face:
- Caliper Body: Die-cast aluminum alloy (same as OEM) — lightweight to reduce unsprung weight (boosting ride comfort and handling) and corrosion-resistant to withstand road salt, rain, and debris (preventing rust that can seize the piston).
- Piston & Seals: Chrome-plated steel piston (resists pitting) and high-temperature EPDM seals (handles up to 300°C brake heat) — ensures smooth piston retraction (avoids “dragging” brakes that waste battery range and wear rotors prematurely) and prevents fluid leaks.
- Pre-Assembled Hardware: Comes with pre-installed guide pins and dust boots, so you don’t need to source separate parts—just bolt it on and connect the brake hose.
Safety is non-negotiable: every caliper undergoes a 3,000 PSI hydraulic pressure test (exceeding industry standards) to eliminate leak points, and the mounting surface is precision-machined to keep the caliper parallel to the rotor—critical for even pad contact and consistent stopping power. It works seamlessly with your Model 3/Y’s original brake pads and rotors, so you only need to replace the faulty caliper (no unnecessary part swaps).
Installation requires intermediate DIY skills (professional installation is recommended for brake components to ensure safety):
- Safely lift the vehicle and remove the right rear wheel.
- Use a line wrench to disconnect the brake hose from the old caliper (avoids damaging the fitting) and remove the caliper mounting bolts.
- Position the CFN caliper, secure it with the original bolts (torque to Tesla’s specification: 85 N·m), and reconnect the brake hose.
- Bleed the rear brake system to remove air bubbles (air in lines causes spongy brakes) and reinstall the wheel.
Note: This is a base-model right-hand rear caliper exclusively for 2022+ Tesla Model 3 and Model Y. It won’t fit 2021 or older Model 3/Y (different brake system geometry) or Performance trims (which use multi-piston calipers). It’s ideal for replacing leaking, seized, or worn rear-right calipers—restoring your Tesla’s stopping performance, protecting brake components from premature wear, and ensuring safe driving.
