21564394 Master Cylinder — Volvo FMX FE Series trucks — FH400

This is a master cylinder, a critical component of the hydraulic braking system in Volvo trucks. It converts the mechanical force applied by the brake pedal into hydraulic pressure, which then actuates the brake calipers or wheel cylinders. A failing master cylinder will result in a spongy or soft brake pedal, reduced braking effectiveness, and potentially a complete loss of braking ability if the internal seals fail.

Failure Symptoms

A soft or spongy brake pedal that requires excessive travel before engaging is the primary symptom of a failing master cylinder. Over time, this will progress to a noticeably longer stopping distance and potentially a situation where the pedal sinks to the floor under braking pressure. Failure to address this can lead to a critical loss of braking capability, posing a significant safety risk.

Installation Tip

Ensure the brake fluid reservoir is filled with the correct type of fluid and that the system is properly bled after installation to remove all air. Do not reuse old brake fluid, as it may contain contaminants.

Service Note

Always bleed the entire brake system thoroughly after replacing the master cylinder to ensure proper brake function.
