Dorman - First Stop Brake Master Cylinder P/N:M390514
$129.99
Turn brake-pedal force into the hydraulic pressure your brakes rely on with the Dorman - First Stop Brake Master Cylinder M390514. It installs as a direct-fit replacement for the 1997-2003 Ford Escort and the 1997-1999 Mercury Tracer, taking over the hydraulic link between the pedal and the brake circuits.
- Hydraulic core of the brake system: houses the pistons and seals that convert pedal input into fluid pressure and push it through the brake lines.
- Signs this part may need replacing: a sinking or spongy pedal, unexplained brake-fluid loss, or reduced braking response. Diagnose the cause first, since other brake components can produce similar symptoms.
- Application-matched: intended as a direct-fit replacement for the listed applications.
If a worn or leaking master cylinder is the cause of your soft or fading pedal, this unit replaces it. Bench-bleed the cylinder and bleed the system per the vehicle service procedure after installation to remove trapped air.
