Keep brake fluid pressure clamping the pads against the rotor with the Carlson disc brake caliper piston (P/N 7009), a direct-fit front replacement for the 2006-2017 Volkswagen Touareg (see the Buyer's Guide tab for the full application list). The caliper piston uses hydraulic pressure to force the brake pads against the rotor, so a scored, seized, or corroded original can drag, stick, or leak — if a failed piston is the cause, this replaces it.
Brakes are engineered as a system, and industry brake-service experts agree that when the friction material is due, the hardware is too. Replacing the piston during a pad or caliper service helps every part work together as intended.
- Front position: cataloged for the front caliper on the listed Touareg applications.
- OE-quality build: manufactured with quality materials held to high tolerances, matching Original Equipment (OE) quality specifications.
- Corrosion-resistant: treated to resist corrosion against harsh road conditions.
- System-minded service: designed to work with the rest of the caliper hardware for consistent pad-to-rotor clamping.
Inspect and rebuild both sides as a set for balanced braking.

Frequently Asked Questions
Does the Carlson disc brake caliper piston 7009 fit my Volkswagen Touareg?
It is cataloged as a front-position replacement for the 2006-2017 Volkswagen Touareg. Check the Buyer's Guide tab to confirm your exact year and configuration.
What does the caliper piston do?
It uses brake fluid pressure to force the brake pads against the rotor. When you press the pedal, hydraulic pressure drives the piston out to clamp the pads.
Is this a front or rear piston?
This part is cataloged for the FRONT caliper on the listed Touareg applications.
What are signs my caliper piston may need replacing?
A piston that is seized, scored, or corroded can cause brake drag, uneven pad wear, or fluid leaks. Diagnose the caliper before replacing to confirm the piston is the cause.
What numbers does part 7009 interchange with?
It cross-references to FH7009 and DPS85217. Match the interchange number against your original piston to confirm.
