Turn brake-line hydraulic pressure into clamping force at the pad with the Carlson Disc Brake Caliper Piston 7194. It installs as a direct-fit replacement for the FRONT brakes of the 2017-2022 Tesla 3 (All), sliding into the caliper bore to do the mechanical work of pushing the brake pad toward the rotor.
Key points:
- Function: Rides in the caliper bore and extends under hydraulic pressure to press the brake pad against the rotor.
- Position: Cataloged for the FRONT brakes on the listed application.
- Quantity: The listed application uses 2 — order accordingly for a complete front-axle replacement, and replace both sides together for even braking.
Signs the original piston may need replacing include the piston sticking or seizing in the bore, fluid seeping past the seal, or uneven pad wear. If a worn or corroded caliper piston is the cause of these symptoms, this replaces it; diagnose the underlying cause before ordering, since braking issues can have other sources.
Manufacturer part number 7194.
