MC183-00100 – McFarlane FAA-PMA Brake Bleeder Cap

Available now on the Airparts.aero Marketplace.

Overview

The McFarlane MC183-00100 is an FAA-PMA approved brake bleeder cap, engineered as a superior, direct replacement for the original cap found on a vast number of Cleveland brake master cylinders. This component is designed to thread onto the brake bleeder screw, providing a clean, protected interface for brake bleeding equipment and keeping the valve free from dirt, moisture, and debris. Manufactured by McFarlane Aviation Technologies from a specialized, high-durability nylon, this cap addresses the common issue of cracking and brittleness found in older, original-equipment caps, ensuring a long-lasting and reliable solution.

Key Features

• High-Durability Nylon Construction: Fabricated from a specialized nylon material that is significantly more durable and resistant to cracking and brittleness compared to the original plastic parts. It is engineered to withstand exposure to hydraulic fluids and the rigors of the maintenance environment.
• Clean & Secure Connection: Provides a clean, standardized port for connecting brake bleeding tools, ensuring a secure, leak-free connection and making the brake bleeding process cleaner and more efficient.
• Protective Function: Seals the top of the bleeder valve, preventing dirt, dust, moisture, and other contaminants from entering the valve and potentially compromising the hydraulic system.
• Direct Replacement: Engineered as a precise, drop-in replacement for Cleveland P/N 183-00100, guaranteeing a perfect fit and function without any modification.
• FAA-PMA Certified: As a certified FAA-PMA part, it has been rigorously tested to meet or exceed the performance and safety standards of the original OEM component, making it a fully airworthy and legal replacement.

Applications

The MC183-00100 is an essential component for safe and effective brake system maintenance:

• Brake System Bleeding: Provides the primary interface for attaching pressure or vacuum brake bleeding equipment.
• Contamination Prevention: Protects the integrity of the hydraulic system by keeping the bleeder port clean between service intervals.
• Component Replacement: A common replacement item during brake servicing, annual inspections, or any time the old cap is found to be missing, cracked, or damaged.

Why Choose MC183-00100?

A clean and properly sealed brake bleeder valve is critical for ensuring that air cannot be inadvertently introduced into the hydraulic system and that the system remains free of contaminants. The McFarlane MC183-00100 offers a tangible upgrade over the original part by using a superior, more durable material. This prevents the common frustration of finding a cracked or broken cap during maintenance and ensures that the bleeder valve is always clean and ready for service. For a simple part that plays a key role in the maintenance of a flight-critical system, the McFarlane PMA replacement is the smart, durable choice.

The brake bleeding procedure is essential for removing air from the hydraulic lines, as air is compressible and will result in a "spongy" or ineffective brake pedal. The MC183-00100 cap threads onto the external part of the bleeder screw, which contains a small orifice. When the screw is slightly loosened, this orifice provides a path for fluid and trapped air to escape. The cap allows a hose from a pressure pot or vacuum system to be securely attached, creating a closed loop that prevents fluid from spilling and air from being drawn back into the system when the pedal is released or pressure is cycled. The McFarlane cap's durable nylon construction ensures this critical interface is always clean and undamaged, ready for a safe and efficient bleeding procedure.

Note: This component should be installed hand-tight. Do not overtighten. It is designed to seal against the bleeder screw, not to hold hydraulic pressure. The bleeder screw itself provides the primary seal for the hydraulic system.
