Dorman - First Stop Brake Master Cylinder P/N:M390188
$104.99
Convert pedal force into the hydraulic pressure that operates the brakes with the Dorman First Stop Brake Master Cylinder M390188. It installs as a direct-fit replacement on the 1994-1996 Dodge Dakota (All engines), engineered to drop in like the original on those listed applications. This unit is 100% new — built entirely of new materials, not remanufactured — so you're not fitting a rebuilt core.
- Aluminum housing: constructed to match the casting material of the original part for similar performance.
- EPDM rubber components: made from a high-quality EPDM compound for resistance to glycol-based brake fluid.
- Two outlets: a rearward outlet sized 1/2-20 and a secondary outlet thread of 9/16-20, with a 24 mm bore diameter.
- Built to standard: made to meet rigorous SAE International specifications.
The master cylinder ships with the reservoir included and does not include a fluid-level sensor. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. If a worn master cylinder is behind a slowly sinking brake pedal, internal fluid bypass, or a leak at the cylinder body, this replaces it. Country of origin: China.
