The 4AN Dry Break Quick Release Clutch/Brake (MPN 4155-04-2) from REDHORSE PERFORMANCE is a quick-disconnect adapter built for clutch and brake fluid lines on race cars and dedicated track builds. It installs inline within an existing -04 AN assembly and lets a crew separate the line without tools, which matters when a transmission, pedal box, or master cylinder has to come out fast between sessions. Both halves of the coupling stop flow when disconnected, so the line stays clean and the system holds its fluid. For builders running braided lines and AN plumbing, this is the piece that makes pulling a component a one-minute job.
Construction is aluminum with a black anodized finish, sealed by a fluorocarbon O-ring rated for the heat and chemical exposure of brake and clutch fluid. Both sides terminate in -04 AN (4AN) male connections, so it threads directly into standard AN hose ends and adapters without an extra step. Operation is simple: push both ends together to mate, then follow the precut channel to separate the halves by hand. The dry break design closes off each side as it disconnects, preventing the spill and air intrusion you get with an open fitting. Pair it with matching 4AN PTFE hose and 4AN unions to keep the whole circuit on one consistent fitting standard.
Reach for this adapter when a clutch line or brake line needs to come apart repeatedly without bleeding the system each time. It suits removable steering columns, quick-swap pedal boxes, and modular bellhousing setups where the same connection gets broken before every teardown. Because it seals on disconnect, you avoid topping off and re-bleeding after routine service. Browse the rest of our fittings, hoses, and valves for the hose ends, caps, and brake line components that finish out a clean AN-plumbed system.
It uses -04 AN (4AN) male connections on both sides, so it threads directly into standard 4AN hose ends, unions, and adapters. Keep the rest of the circuit on matching 4AN fittings for a leak-free connection.
Yes. The dry break design closes off both halves as they separate, which prevents fluid spillage and keeps air out of the clutch or brake system. That means you can break the connection without re-bleeding the line each time.
No tools are required. Push both ends together to mate the coupling, then follow the precut channel to separate the halves by hand. It's built for fast, repeated disconnects during teardown and service.
The body is aluminum with a black anodized finish, and it seals with a fluorocarbon O-ring suited to the heat and chemical exposure of brake and clutch fluid.
