Product Details

The Dorman M639012 is a direct-fit replacement brake master cylinder engineered to restore proper braking system function. Precision-manufactured to match original equipment specifications, this master cylinder delivers the same performance, feel, and reliability as the factory unit it replaces.

Key Features:

  • Precision-engineered to match OE design, function, and dimensions
  • Manufactured from new, high-quality materials — not remanufactured
  • Restores proper brake pedal feel and hydraulic pressure output
  • Designed for a direct, hassle-free installation
  • Built to meet or exceed original equipment performance standards
  • Safe, durable construction for long-term reliability

As the heart of the hydraulic braking system, the brake master cylinder converts pedal force into hydraulic pressure to actuate the brake calipers and wheel cylinders. A worn or leaking master cylinder can result in a spongy pedal, reduced stopping power, or complete brake failure. The Dorman M639012 provides a dependable, quality replacement to restore full braking confidence.

Great merchant! I would most certainly would do business with them again. Customer Service was extremely helpful and my order shipped quickly.

Fast shipping, Great prices. After ordering,they sent out an email stating some items ordered may ship from the manufacturer. So, I was thinking item may take a few weeks to get. The next day I recieved email with tracking numbers saying item has shipped. So I was think ups ground 5 days maybe. I check on tracking numbers and items was out on truck for deliver. Nice! Ordered on Weekend got item on Tuesday.
