Brake System Function

The master cylinder is responsible for converting mechanical brake-pedal force into hydraulic pressure.

A failing master cylinder may cause:

• Soft or spongy brake pedal

• Reduced braking performance

• Uneven or inconsistent braking

Replacing a defective master cylinder can help restore proper hydraulic brake operation when the rest of the braking system is in good condition.
