Frequently Asked Questions
Q: What vehicles are these alternator carbon brushes compatible with?
A: These carbon brushes are designed as universal replacements for many car alternators and voltage regulators that use brush sizes of 4.5 × 6.5 × 20 mm, 5 × 7 × 20 mm, or 5 × 8 × 20 mm. We recommend measuring your existing brushes or checking your vehicle's alternator specifications before purchase to confirm fitment.
Q: Why do alternator brushes need to be replaced?
A: Alternator carbon brushes transfer electrical current to the rotating slip rings inside the alternator. Over time, normal wear reduces their length, leading to reduced charging output or a complete charging failure. Replacing worn brushes with fresh carbon and copper alloy units restores proper electrical contact and charging performance.
Q: How do I know which size brush I need?
A: Remove the old brushes from your alternator or voltage regulator and measure the width, height, and length (in mm). Compare your measurements to the three sizes included in this pack — 4.5 × 6.5 × 20 mm, 5 × 7 × 20 mm, and 5 × 8 × 20 mm — and select the closest match. Having all three sizes in one purchase saves time and ensures you have a spare on hand.
