Brake Master Cylinder for a 1974 Ford Bronco
Vehicle: 1974 Ford Bronco (early "half-cab" generation)
Note: The Bronco is a Ford product, not Chevrolet. If the vehicle in question is a 1974 Chevy truck (such as a K5 Blazer or C/K pickup), the parts below will not apply.
Vehicle & Part Overview
The 1974 Ford Bronco uses either a single-circuit or early dual-circuit brake master cylinder, depending on the specific build. The correct replacement depends on two key factors:
- Brake configuration — whether the Bronco has front disc or front drum brakes
- Bore size and port configuration — which varies based on the above
Confirm the existing brake setup before ordering to ensure correct fitment.
Sourcing Recommendations
- Dennis Carpenter Ford Restoration Parts — Specializes in early Ford trucks and Broncos; frequently stocks correct original-style replacement master cylinders
- National Parts Depot — Broad inventory of brake components for this era of Ford trucks
- Inline Tube — Handles brake system components for classic trucks; a strong option for quality rebuilt units or performance upgrades
Safety & Fitment Notes
Disc vs. drum brakes: The bore size and port configuration of the master cylinder differ between front disc and front drum brake setups. Installing the wrong unit can result in improper brake pressure and unsafe stopping performance. Verify the front brake type before purchasing.
- If keeping the Bronco stock, prioritize original-style replacements from Dennis Carpenter or National Parts Depot.
- If upgrading to a disc brake conversion, the master cylinder selection will differ — confirm the full brake system specification before sourcing parts.
