GiroDisc CCRK1-146 Front Caliper Rebuild Kit for 2012-Present Porsche 911/981

Vehicle Fitment

• 2012-2018 Porsche 911 (991-series) GT3 / GT3 RS / Turbo / Turbo S (front calipers, 30 mm/30 mm/30 mm piston setup)
• 2015-2016 Porsche 981 Cayman GT4 / 981 Boxster Spyder (front calipers, same piston spec)
• 2016-present Porsche 718 Cayman GT4 / 718 Boxster Spyder (982-series, front calipers as above)
• Other Porsche 911 / 981 / 982 variants using the same front 30 mm piston-caliper architecture (check piston size before ordering)

Features

• Complete rebuild kit for one front caliper - includes all seals and dust-boots required
• Restores caliper piston seals and boots, returning caliper to like-new condition
• Designed for high-performance / track-use conditions - ideal after heavy use, heat, or seal degradation
• Made to exacting specifications for durability and consistent braking performance
• Helps prevent leaks, piston corrosion and seal failure - extends caliper service life
• Allows reuse of caliper housing and pistons - cost-effective compared to caliper replacement
• Made in USA - manufactured to high quality standards for performance vehicles
• Simple install - rebuild one caliper with basic tools; no special machining required

Product Description

The GiroDisc CCRK1-146 Caliper Rebuild Kit is engineered to bring front brake calipers back to like-new condition for many Porsche 911 (991-series), Cayman/Boxster GT4 (981), and 718 GT4-Spyder (982) models - anywhere the front calipers use the 30 mm/30 mm/30 mm piston configuration. Over time, piston seals and dust boots can deteriorate - especially after repeated heat cycles from track use - which may lead to leaks, reduced braking performance, or piston corrosion. This kit replaces all rubber sealing components, effectively renewing the caliper without replacing the entire unit.

Because the kit includes high-quality precision-spec dust boots and seals, the rebuilt caliper will again provide proper piston sealing and dust protection. This restores consistent brake feel, full hydraulic pressure integrity, and protects against ingress of dirt or moisture. The rebuild is a cost-effective way to extend the service life of expensive calipers - especially if the caliper body and pistons remain in good condition. Installation is straightforward with standard tools; once assembled, paired with proper pads and fluid, the caliper is ready for street or track duty. For Porsche owners wanting a reliable brake rebuild after heavy use or preparing for more spirited driving, CCRK1-146 is a practical and high-quality solution.
