Dorman Brake Master Cylinder M76162 — 100% New OE-Style Replacement with EPDM Seals

This master cylinder is manufactured to match the original component's design, materials, and performance characteristics so you can replace a worn or leaking unit without compromising safety or pedal feel. Constructed from new materials and built to SAE standards, the M76162 uses EPDM rubber parts for long-term resistance to glycol-based brake fluids and is engineered to fit specific years, makes, and models when you verify fitment with the vehicle lookup tool.

How does this master cylinder compare to the original equipment unit?

The M76162 is made to mirror the original cylinder’s housing casting and functional design so it behaves like the factory part under normal driving conditions. Because it is 100% new rather than remanufactured, it avoids common reman issues such as worn bore surfaces or compromised seals.

• Housing cast to match original material and dimensions
• New internal components for consistent bore finish
• EPDM rubber seals designed for brake fluid compatibility
• Manufactured to meet SAE International standards

What features help the M76162 resist degradation from brake fluid?

Critical elastomers are molded from EPDM, a synthetic rubber that resists swelling and deterioration when exposed to glycol-based brake fluids. This choice of material helps preserve sealing performance and prevents leaks that can lead to reduced braking effectiveness.

• All rubber parts made from EPDM compound
• Chemical resistance to common brake fluids to reduce swelling
• Durable seal geometry to maintain pressure integrity

How do I confirm the M76162 will fit my vehicle?

Because master cylinder dimensions, port locations, and mounting provisions vary, use the seller’s vehicle compatibility or garage tool to enter your vehicle year, make, model, and trim. Verifying fit prevents returns and ensures the ports and mounting studs align with your brake system.

• Use VIN or year/make/model lookup on the product page
• Compare mounting hole locations and reservoir type before installation
• Check brake line and sensor port compatibility if applicable

What should I expect during installation and service life?

Installation follows standard master cylinder replacement steps: bench-bleeding the new unit, careful line reconnection, and system bleeding to remove air. When installed correctly and paired with proper maintenance, the new components and EPDM seals provide reliable service life similar to the original component.

• Bench-bleed before mounting to remove trapped air
• Follow vehicle-specific torque specs for mounting bolts
• Bleed the entire brake system after installation for correct pedal feel

Who is this for: The Dorman M76162 is intended for DIY mechanics and professional technicians replacing a failed or leaking brake master cylinder on compatible vehicles that require an OEM-style, all-new unit. It suits owners who want a direct-fit replacement made from new materials and molded rubbers optimized for brake fluid resistance, and who will verify fitment with the vehicle lookup to ensure correct installation.
