Frequently Asked Questions

Will this fit my 1988+ Softail or Sportster?

This part is specific to 1986-1987 FL Softail and 1982-1987 XL Sportster. Later model years may use different bore sizes or mounting configurations — verify before ordering.

Is this chrome-plated or polished aluminum?

Chrome-plated steel. It delivers a classic chrome look and is corrosion-resistant for long-term durability.

Do I need to replace the brake lines when I install this?

Inspect existing lines for cracks or swelling. If they're in good condition, reuse them. If worn, replace them at the same time for safety.

What's included?

The master cylinder assembly only. Brake fluid and installation hardware (if needed) are sold separately.

Is professional installation required?

Brake system work should be performed by someone with mechanical experience. If unfamiliar with brake service, have a shop complete the installation and bleed the system.
