Brake Master Cylinder — 1974 Ford Bronco or 1974 Chevy K5 Blazer / C/K Truck
Vehicle Clarification
The Bronco is a Ford product, not a Chevrolet. These are two distinct vehicles:
- 1974 Ford Bronco — early "half-cab" generation, built by Ford
- 1974 Chevy K5 Blazer / C10 / C20 / C/K truck — the GM equivalent from the same era, sharing components across the C/K truck line
Identify which vehicle you have before sourcing parts, as the master cylinders are not interchangeable.
Vehicle & Part Overview
1974 Ford Bronco
The original master cylinder on the early Bronco is either a single-circuit or early dual-circuit unit, depending on the specific build date and configuration.
Before ordering, confirm:
- Whether the Bronco has front disc or front drum brakes
- This directly affects the required bore size and port configuration of the replacement master cylinder
1974 Chevy K5 Blazer / C/K Truck
The master cylinder for this generation of GM trucks is a separate fitment from the Ford unit. The same disc-vs-drum confirmation applies before ordering.

Fitment & Safety Notes
Confirm your brake configuration before ordering. Whether the front axle runs disc or drum brakes determines the correct bore size and port layout of the master cylinder. Installing the wrong unit can result in improper brake pressure and brake failure.
- If keeping the vehicle stock, source an original-style or correct-spec replacement
- If performing or planning a disc brake conversion, the master cylinder must be matched to the upgraded system — confirm compatibility with your supplier before purchasing
- Cross-reference your vehicle's build details (disc vs. drum, single vs. dual circuit) against the part listing before finalizing any order
