✔ Fitment Confidence: This kit is designed for compatible six-cylinder, 4-lug Ford and Mercury applications.

We’ll help confirm the correct application details so you can buy with confidence.

Important Compatibility Note

The included master cylinder will not bolt to the stock booster on vehicles originally equipped with power drum brakes. Confirm your non-power brake configuration before ordering.

Wheel and Installation Notes

This system fits many 14-inch and 15-inch wheels when clearance is confirmed. Professional installation is recommended. Confirm spindle compatibility, wheel clearance, brake-line routing, master-cylinder setup, and proportioning requirements before installation. The system must be properly bled and the pads and rotors correctly bedded after installation.
