Buying Guide

Material matters

Choose copper-nickel or stainless steel tubing for superior corrosion resistance and easier bending compared with plain steel

Check included fittings and tools

Kits that include brass fittings, unions, and a flaring tool reduce trips to the parts store and simplify installation

Match master cylinder fitment

Confirm OEM-style ports, pushrod length, and vehicle-specific fitment for Dorman or aftermarket master cylinder replacements

Bleeder adapters aid bleeding

Use the correct GM-style or universal bleeder adapter to seal the cap and streamline vacuum or pressure bleeding procedures

Line diameter and flare type

Select the correct tubing diameter (3/16" vs 1/4") and single/double-flare compatibility to match existing brake fittings
