Generate the hydraulic pressure that operates the brakes with the Dorman - First Stop Brake Master Cylinder (M630296). When you press the pedal, the master cylinder converts that force into hydraulic pressure and sends it through two outlets to the brake circuits. It installs as a direct-fit replacement for the 2004 Acura TL [All] and 2003-2004 Honda Accord [All], precision-engineered to match the design, function, and performance of the original unit on these applications.
Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.

What are signs the master cylinder may need replacing?
A brake pedal that slowly sinks under steady pressure, a spongy feel, or internal fluid loss can indicate a failing master cylinder. Diagnose the cause before replacing, as other components can produce similar signs.
