Raybestos Brake Master Cylinder Repair Kit MK166 Machined

Description

Product Overview

The Raybestos MK166 Master Cylinder Repair Kit is engineered to meet the exacting standards of original equipment manufacturers while providing modern technicians with a hassle‑free solution. Crafted from high‑strength machined aluminum, the cylinder body offers superior rigidity and resistance to corrosion, ensuring a long service life even in demanding environments. The kit includes a fully assembled master cylinder that has been pressure‑tested at the end of the production line, guaranteeing consistent performance from the first pump to the last mile.

Every component of the MK166 kit is selected for its durability and precision. The internal seals are made from a proprietary polymer blend that maintains elasticity across a wide temperature range, preventing leaks and maintaining hydraulic pressure. The piston rod is hardened steel, polished to a fine finish to reduce friction and wear. Together, these materials create a hydraulic system that mimics the feel of the original equipment while delivering enhanced reliability.

Key specifications include a weight of just 3.2 ounces, a machined exterior finish for easy identification, and a model number of MK166 that matches both the manufacturer and OEM part numbers. The kit is designed for the primary brake cylinder repair market, positioning it as a direct replacement for worn or damaged units in classic vehicles.

Vehicle compatibility spans a broad range of classic American Motors and Edsel models, including the 1959‑1958 American Motors Rebel, 1958 Edsel Bermuda, Edsel Citation, Edsel Corsair, Edsel Pacer, Edsel Ranger, Edsel Roundup, Edsel Villager, and many 1960‑1963 Ford applications. This extensive fit list means that a single kit can service multiple vehicle platforms, reducing inventory complexity for parts distributors and repair shops.

Installation is streamlined by the kit’s ready‑to‑bench‑bleed design. Technicians can attach the cylinder to a standard bench bleeding rig, purge air from the system, and install the unit without additional assembly steps. The absence of extra hardware not only speeds up the repair process but also minimizes the risk of installation errors that could compromise brake performance.

Performance testing demonstrates that the MK166 maintains consistent pedal feel and hydraulic pressure under both light and heavy braking scenarios. The precision‑machined bore and piston ensure smooth operation, while the high‑quality seals prevent internal leakage, delivering a braking response that feels both natural and confident.

Durability is further reinforced by Raybestos’ rigorous quality control procedures. Each master cylinder undergoes a 100% end‑of‑line pressure test, simulating real‑world braking forces to verify that the unit can withstand the demands of daily driving and occasional high‑stress events. This testing regime helps to eliminate defective parts before they reach the market.

Raybestos, a trusted name in automotive braking components for decades, backs the MK166 with a reputation for engineering excellence. The brand’s commitment to safety and performance is reflected in the meticulous design and manufacturing processes that go into every master cylinder. Customers benefit from a product that not only meets OEM specifications but also exceeds them in terms of material quality and reliability.

The MK166 is an ideal choice for professional mechanics, restoration specialists, and DIY enthusiasts who require a dependable brake component for classic vehicles. Its compatibility with a wide range of models makes it a versatile addition to any workshop inventory, while the ease of installation reduces labor time and associated costs.
