Description

Help maintain firm, consistent pedal feel with the Dorman brake master cylinder M630825 from Dorman - First Stop. This is the component that turns the force on your brake pedal into hydraulic pressure for the brake system. It is a direct-fit replacement for the 2008-2009 Pontiac G8. See the "Vehicles it fits" section for engine-level details.

Precise replacement: Precision-engineered to mirror the original master cylinder's design, function and performance on the listed applications. The housing's casting material matches that of the original part for similar performance.
Durable design: Every rubber component uses a high-quality EPDM compound chosen for its resistance to glycol-based brake fluid.
100% new: Built entirely from new materials, with a focus on quality and safety.
Strict specifications: Produced to meet rigorous SAE International standards.

Signs that a master cylinder may need replacing include a soft or slowly sinking brake pedal, brake fluid leaking at the cylinder, or a low-fluid warning. Other brake components can cause these same symptoms, so diagnose the cause before replacing the master cylinder. If the original master cylinder is the fault, M630825 replaces it.

Buyer's Q&A

Frequently Asked Questions

What does a Dorman master cylinder do?

It converts the force applied to the brake pedal into hydraulic pressure. That pressure is sent through the brake lines to apply the brakes.

Does this brake master cylinder fit the 2008-2009 Pontiac G8?

Yes. M630825 is listed as a direct-fit replacement for the 2008-2009 Pontiac G8. Engine-level details are in the "Vehicles it fits" section.

What are the rubber components made of?

All rubber components are made from a high-quality EPDM compound, chosen for its resistance to glycol-based brake fluid.

What signs suggest the master cylinder may need replacing?

Warning signs include a soft or slowly sinking pedal, fluid leaking at the cylinder, or a low brake fluid warning. Other brake parts can cause these too, so diagnose the cause first.

Does it need to be bled during installation?

Master cylinders are generally bench-bled before installation, and the brake system is bled afterward. Follow the vehicle service information for the correct procedure.
