Dorman - First Stop Brake Master Cylinder P/N:M630041
$131.99
Turn every push of the brake pedal into the hydraulic pressure your brakes rely on with the Dorman First Stop Brake Master Cylinder M630041. It drops in as a direct-fit replacement for the 2001-2005 Pontiac Aztek [All] and 2002-2007 Buick Rendezvous [All], precision-engineered to match the design, function, and performance of the original master cylinder on those listed applications.
The master cylinder is the hydraulic heart of the brake system, converting pedal effort into the pressure that actuates the brakes. This aluminum unit has two outlets and a 1-inch bore, with a 1/2-20 rearward (secondary) outlet thread, and it ships with the reservoir and sensor already fitted.
- Aluminum housing: constructed to match the casting material of the original part for similar performance.
- Durable EPDM seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: made entirely of new materials, not remanufactured, for consistent quality.
- Built to standard: made to meet rigorous SAE International standards.
Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. If a failed master cylinder is the cause of a sinking or spongy pedal or fluid loss, this replaces it. Country of origin: China.
