CFN Brand Left-Hand Rear Brake Caliper (Base) for Tesla Model 3/Model Y (2022+) | 1044625-00-B

If your 2022+ Tesla Model 3 or Model Y’s left rear brake caliper is leaking fluid, sticking (causing uneven brake wear), or failing to engage smoothly—this CFN left-hand rear base brake caliper is the critical safety component to restore reliable braking performance. As an engineered replacement (not Tesla OEM), it’s built to match the 2022+ Model 3/Y’s original caliper specs: from piston diameter and mounting hole alignment to hydraulic pressure tolerance, ensuring it integrates seamlessly with your vehicle’s brake system and meets Tesla’s braking performance standards.

Brake calipers are the “heart” of your Tesla’s braking system: they house the brake pistons that clamp down on the rear rotor (when you press the brake pedal), converting hydraulic pressure into friction to slow the vehicle. This CFN base caliper is designed for the 2022+ Model 3/Y’s rear-left wheel, with a single-piston (base configuration) setup that mirrors the factory’s balanced braking design—no over- or under-braking that could lead to skidding or uneven rotor wear. Unlike generic calipers that may not align with Tesla’s hydraulic system, this one fits the original brake hose connections, mounting brackets, and torque specifications perfectly—so you won’t face issues like fluid leaks or misaligned pistons.

Durability is non-negotiable for brake components, and this caliper delivers:

Body Material: Die-cast aluminum alloy (same as OEM), which is lightweight (reducing unsprung weight for better ride quality) and corrosion-resistant (critical for rear calipers exposed to road salt, rain, and debris).
Piston & Seals: High-temperature resistant EPDM seals and a chrome-plated steel piston—preventing seal degradation from brake heat (up to 300°C) and ensuring smooth piston retraction (avoids “dragging” brakes that waste range and wear rotors prematurely).
Pre-Assembled for Ease: Comes with pre-installed guide pins and boot covers, so you don’t need to source separate hardware—just bolt it on, connect the brake hose, and bleed the system.

Safety is prioritized in every detail: the caliper’s hydraulic chamber is pressure-tested to 3,000 PSI (exceeding industry standards) to eliminate leak risks, and its mounting flange is precision-machined to match the 2022+ Model 3/Y’s rear knuckle—ensuring the caliper sits perfectly parallel to the rotor (a must for even brake pad contact). It also works with the original brake pads and rotors, so you don’t need to replace other components unless they’re worn—saving time and cost.

Installing it requires intermediate DIY skills (or professional service, recommended for brake components):

Safely lift the vehicle and remove the left rear wheel.
Disconnect the brake hose from the old caliper (use a line wrench to avoid damaging the fitting) and remove the caliper mounting bolts.
Swap in the CFN caliper, secure it with the original bolts (torque to Tesla’s spec: 85 N·m), and reconnect the brake hose.
Bleed the rear brake system to remove air bubbles (critical for consistent braking) and reinstall the wheel.

Note: This is a base-model left-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 design) or Performance trims (which use multi-piston calipers). It’s ideal for replacing faulty, leaking, or seized rear-left calipers—restoring your Tesla’s stopping power, extending brake component life, and ensuring safe driving.
