Buying Guide: Key Purchase Considerations
What should you check before buying a master cylinder push rod kit? Look for adjustable length options (7 to 7.5 inches is common) and an eyelet size of 5/8 inch, which aligns with many classic pedal assemblies. Consider whether the rod can be shortened to 5 1/8 inches, which improves compatibility with shorter booster setups. Durability matters; metal construction resists wear in high-pressure braking. A complete kit with clevises, nuts, and boots simplifies installation and protects linkage from dust and moisture.
How to determine the best fit for your vehicle? Identify your car’s model year range, then match the kit’s listed compatibility (e.g., 1964–1973 GM or Ford). If you have a GM restoration, kits framed for A1726 CI5564 fitment may be particularly relevant. For Ford enthusiasts, look for the specific F-ord compatibility and the ability to adjust to precise pedal geometry.
What installation considerations matter? Ensure the push rod’s length aligns the master cylinder piston with the booster pushrod so there is no binding. If you need to cut the threaded portion, do so carefully and recheck the alignment. A rubber boot helps seal the linkage against dust and moisture in many kits.
FAQ
