Description

Firm up your brake pedal and keep hydraulic pressure flowing with the Dorman - First Stop Brake Master Cylinder M630144. It installs as a direct-fit replacement for the 2000-2004 Toyota Celica, converting the force from your brake pedal into the hydraulic pressure that operates the brakes.

The master cylinder is the heart of the hydraulic brake system: as you press the pedal, it pushes brake fluid through the lines to the wheel calipers and cylinders. Over time, internal seals can wear and allow fluid to bypass, producing a soft, sinking, or spongy pedal. If a failed master cylinder is the cause of those symptoms, this unit replaces it.

Function: Generates and distributes the hydraulic pressure that applies the vehicle's brakes.
Direct-fit application: Designed for the listed 2000-2004 Toyota Celica.
Common signs of a worn master cylinder: a soft or sinking pedal, or gradual loss of braking feel — diagnose the cause before replacing.

Always bleed the brake system after installation and confirm correct pedal feel before driving.
