Dorman - First Stop Brake Master Cylinder P/N:M390362
$135.99
Keep firm hydraulic pressure moving to every wheel with the Dorman - First Stop Brake Master Cylinder M390362. It installs as a direct-fit replacement for the 1997-1998 Buick Century, 1997-1998 Buick Regal, 1998 and 2000-2002 Oldsmobile Intrigue, and 1997 Pontiac Grand Prix.
The master cylinder is the hydraulic heart of the brake system: it converts the force you apply at the pedal into the fluid pressure that operates the brake circuits at each wheel.
- Hydraulic conversion: turns brake-pedal force into the fluid pressure that acts on the calipers and wheel cylinders.
- Direct-fit application: designed to install on the listed vehicles.
- Signs it may need replacing: a pedal that slowly sinks under steady pressure, a spongy or low pedal, or brake-fluid loss with no external leak can indicate a worn master cylinder — diagnose the cause before replacing.
If a failed master cylinder is the cause of your soft or sinking pedal, this unit replaces it.
