Dorman - First Stop Brake Master Cylinder P/N:M390471
$210.99
The brake master cylinder is the hydraulic heart of your brake system, converting the force of your foot on the pedal into pressurized brake fluid that travels out to the wheel circuits. The Dorman - First Stop Brake Master Cylinder M390471 is a direct-fit replacement for the 1997-1998 Acura Integra and 1997-1998 Acura TL.
- Core job: Turns brake-pedal force into hydraulic pressure to actuate the brakes at each wheel.
- Signs it may need replacing: a pedal that slowly sinks under steady foot pressure, a soft or fading pedal, or unexplained brake-fluid loss. Diagnose the cause before replacing, since these symptoms can have other sources.
- Direct fit: installs on the listed Acura applications to replace a worn or internally leaking original.
Replaces a master cylinder that is bypassing internally or losing fluid. After installation, bleed the brake system per the vehicle service procedure to remove air and restore a firm pedal.
