Dorman Brake Master Cylinder M76162 — Direct-Fit Replacement, All-New EPDM Seals for OEM Fit

The Dorman M76162 Brake Master Cylinder is a 100% new, direct-fit replacement engineered to match OEM design and restore reliable brake-fluid pressure on specified vehicle applications.

This master cylinder is manufactured from all-new materials and built to mirror the original unit’s casting, port layout, and performance characteristics so it installs and functions like the factory part. Its rubber seals and internal components use an EPDM compound that resists glycol-based brake fluid and helps prolong service life. Designed and tested to SAE International standards, this unit provides a durable, safe replacement when the original master cylinder leaks, seizes, or no longer maintains proper hydraulic pressure.

What makes the M76162 a reliable replacement for my vehicle?

The Dorman M76162 reproduces the casting materials, bore dimensions, and mounting points of the original master cylinder so it fits and functions with existing brake lines, boosters, and reservoirs. Because it is manufactured as a completely new part rather than a remanufactured unit, you avoid issues tied to previous wear or hidden damage.

• Precision-matched housing for correct fit and alignment
• New internals and pistons for consistent hydraulic feel
• EPDM rubber components resist common brake fluids
• Built to meet SAE performance and safety specs

How does installation and compatibility work for this master cylinder?

Installers should confirm fitment by entering vehicle year, make, model, and trim in the product garage tool before ordering to ensure correct ports and mounting. The unit uses the same bolt locations and port spacing as the original for a straightforward swap, typically requiring standard hand tools and brake-bleeding equipment for final setup.

• Check the garage tool for exact vehicle application
• Direct-fit mounting points streamline installation
• Standard brake bleeding required after installation
• No remanufactured internals—new components only

What materials and standards are used in this Dorman master cylinder?

Components are made from materials chosen to replicate the original casting and provide long-term durability. Rubber seals are EPDM to resist glycol-based fluids, and the entire assembly is produced to meet rigorous SAE International manufacturing and performance standards.

• Casting matched to OEM material for structural similarity
• EPDM rubber for chemical resistance and longevity
• All-new construction—no remanufactured parts
• Manufactured to SAE specifications for performance

Who is this for? The Dorman M76162 is aimed at DIY mechanics, professional technicians, and vehicle owners who need a dependable, like-for-like master cylinder replacement for supported vehicles. It’s suitable when the original unit shows leaks, internal wear, or fails to hold hydraulic pressure, and for anyone who prefers a brand-new component built to match OEM form and function rather than a remanufactured option. Always verify vehicle compatibility with the garage tool before purchase and follow recommended brake-bleeding procedures and safety practices during installation.
