Baer Brakes 6801213LP ReMaster Billet Aluminum Master Cylinder Bore Port - 1in Left Polished

The Baer Brakes 6801213LP ReMaster is a fully machined, high-performance brake master cylinder built for demanding street and track applications. Constructed as a single-piece body from 6061 T6 billet aluminum, this compact master cylinder delivers a precise 1-inch bore with left side port exits and mounts via a 2-bolt firewall flange compatible with many GM and Ford applications.

The billet lid is secured with six Allen screws and features two large, machined and knurled screw-on caps for easy, spill-free brake fluid access. The polished finish is complemented by laser-etched logos and part numbers for a clean, finished appearance under the hood.

Note: Some long push rod hydroboost and vacuum boosters may require an additional spacer (p/n 6260258) to provide proper clearance from the booster push rod.
