The 1974 Ford Bronco uses a single-circuit master cylinder. Ford did not introduce dual-circuit brakes on the early Bronco until a later production run, so confirming you source the correct single-circuit type for this application is essential.
Key specification to verify before ordering:
Standard bore diameter is typically 1 inch — measure the existing unit if possible to avoid a return
Confirm your brake configuration (see fitment notes below)
Sourcing Recommendations
Dennis Carpenter Ford Restoration Parts — specializes in Ford trucks and early Broncos, stocks correct OEM-style replacements
Confirm your brake configuration before ordering. Some 1974 Bronco models were optioned with front disc brakes. A front-disc setup requires a different master cylinder specification than an all-drum configuration. Ordering without verifying this detail is the most common cause of incorrect fitment on this application.
Two things to check before purchasing:
Brake setup — all drums, or disc brakes on the front axle
Bore diameter — measure the existing master cylinder; standard is ~1 inch, but confirming this avoids compatibility issues
Where to Find It
Dennis Carpenter Ford Restoration Parts
Specializes in Ford trucks and early Broncos, carries correct OEM-style replacements
Classic Ford — Cortina, Capri, Escort, Anglia, Zephyr, Consul, and Classic — is among the best-supported British classic categories with one of the largest aftermarket supply networks in the UK. Heritage Parts Centre, Burton Power, and Speedograph Richfield carry comprehensive component libraries. The Kent crossflow and Pinto engines have vast tuning and rebuild options. Escort Mexico and RS2000 body panels are actively reproduced. The Ford Cortina Owners Club and Capri Club International run spares schemes for scarce items. US-market Ford classics (Mustang, Thunderbird, early F-Series) are equally well covered through suppliers like National Parts Depot.
When sourcing Master Cylinder for a classic car, it pays to verify the exact part specification against the vehicle's build date rather than model year alone — British Leyland cars in particular changed specifications mid-year without fanfare. Cross-referencing the original part number against multiple supplier catalogues often reveals equivalent components at different price points. For NLA items, owner club spares registers, eBay sold listings, and specialist forums are frequently the only viable route.
Finding parts for 1974 Ford Bronco can be challenging. If the results above don't cover what you need, Geoff can search further.
