Moto Iron Front Brake Master Cylinder for 1996-2017 Harley-Davidson

Whether blacking out a bike, repairing a badly corroded master cylinder on a stock bike or reworking a brake system or building something custom, sometimes a rebuilt unit just won't do. This Moto Iron unit has features that make it easy to integrate with stock H-D controls so your brake work doesn't turn into redesigning a whole front end.

Choice of 9/16" or 11/16" bore
- On OEM bikes, single-disc forks usually are fitted with master cylinders with a 9/16" bore and dual-disc forks use master cylinders with a 5/8" or 11/16" bore—but not always; please verify your bore size before ordering
Includes lever and clamp
- 7/16"-24 banjo bolt and crush washers included on 9/16" bore master cylinders
- 3/8"-24 banjo bolt and crush washers included on 11/16" bore master cylinders
Compatible with DOT 4 or 5 brake fluid—this is a safety-critical consideration many other master cylinders may not support
Compatible with most 1" diameter handlebars
Allows reuse of your OE brake switch (one is not included)

This master cylinder comes with a lever, but it accepts OEM levers as well. It's notched to work with 1996-2017 Harley-Davidson switch housings and is a great way to convert bore sizes, replace a master cylinder that's too far gone to rebuild, or just spiff up a bike that lived outside that might have ratty-looking controls.

1996-2014 Harley-Davidson Softail
1996-2017 Harley-Davidson Dyna
1996-2007 Harley-Davidson Touring
1996-2003 Harley-Davidson Sportster
Generally, single-disc forks use master cylinders with a 9/16" bore and dual-disc forks use master cylinders with either a 5/8" or 11/16" bore; best practice involves removing your OEM master cylinder to examine the bore size, which is usually cast into the housing itself
