Brake Pressure Switches

Brake Pressure Switches – Classic Ford (1932–1979)

A hydraulic brake pressure switch completes the brake light circuit when hydraulic pressure rises in the brake system, making it a critical electrical component in classic Ford cars and trucks from 1932–1979. Used on drum brake systems and later disc/drum configurations, these switches typically mount at the master cylinder or distribution block and respond directly to brake pedal application.

Correct selection depends on model year, body style, brake configuration, and master cylinder design. Early single-reservoir systems and later dual-reservoir conversions may use different thread sizes or terminal styles. During restoration, prior modifications such as updated master cylinders or wiring repairs can affect compatibility. A properly matched hydraulic brake pressure switch or mechanical brake switch ensures consistent brake light activation and maintains factory-correct function within the braking circuit.

Since 1978, C&G Ford Parts has remained a second-generation, family-owned business focused exclusively on classic Ford vehicles. Our staff works with these components daily and is available to help confirm correct fitment when details matter.
