Dorman - First Stop Brake Master Cylinder P/N:M390277

$179.99

Description

Restore firm, dependable brake-pedal feel with the Dorman - First Stop Brake Master Cylinder (M390277). It drops in as a direct-fit replacement for the 1995-1999 Chevrolet Cavalier and 1995-1999 Pontiac Sunfire, taking the place of a worn or internally leaking original.

The master cylinder is the heart of the hydraulic brake system: it converts the force you apply at the brake pedal into hydraulic pressure that travels through the lines to operate the calipers and wheel cylinders. When the original develops internal bypass or an external leak, braking response suffers.

Direct fit: designed to install on the listed applications.
Hydraulic function: converts brake-pedal force into hydraulic pressure for the brake circuits.
Signs it may need replacing: a pedal that slowly sinks under steady foot pressure, a spongy or low pedal, or visible fluid seepage at the cylinder. Diagnose the cause first, since these symptoms can have other sources.

What does a brake master cylinder do?

It converts the force from your brake pedal into hydraulic pressure, sending brake fluid through the lines to the calipers and wheel cylinders to slow the vehicle.

How do I know if my master cylinder is failing?

Common signs include a pedal that slowly sinks under steady pressure, a spongy or low pedal, or fluid leaking at the cylinder. Have the cause diagnosed before replacing.

What is the manufacturer part number?
