Customer Reviews


Master cylinder

By Thomas A. on  Verified Purchaser

The master cylinder quality was excellent original equipment and the price was well within reason. All in all job well done!


Just what I needed

By Paul C. on  Verified Purchaser

Just what I needed. Works fine good price.


Front brake handle/reservoir replacement

By William W. on  Verified Purchaser

Fit was just like factory. Looks good with all the other chrome.


Perfect for larger diameter handlebars

By Sean M. on  Verified Purchaser

Purchased this item to resolve a clearance issue when I upgraded bars. The old handle bars were 1" diameter. The new bars were 1.25" diameter. When I went to put the old master cylinder on the new bars, the brake fluid reservoir was hitting the handle bars where it stepped up to 1.25", preventing it from mounting flush. This drag specialty master cylinder clamped on the 1" grip section perfectly, and cleared the 1.25" section with no issues.


Just what I needed.

By John B. on  Verified Purchaser

Put it on and all works great. Just what I needed.

Works great with plenty of clearance

By Ben B. on  Verified Purchaser

I purchased this master cylinder because the stock MS on my 2000 screaming Eagle road glide didn't work with the Dominator 1 1/4 bars I upgraded to. This master cylinder from drag specialties works great with plenty of clearance. Thanks!

Questions & Answers


Will this interface with my 2008 FXDWGI stock front brake switch?

By Ron

Yes, these Drag Specialties master cylinders are designed to work with the remaining stock components on any machine you select from our fit guide, including the 2008 Fat Boy.

By Tom

How do I know if my bike has the 9/16 or 11/16 bore? Does it matter? I have a 1999 sportster 883

By jack

You can employ either master cylinder bore on a machine with a single brake disc, but if your machine has a dual-disc front brake setup, you'll want to use the bigger master cylinder bore. Basically, the bigger the brake master bore, the more fluid is moved, when compared to the smaller bore, for the same amount of lever movement. That is to say, the bigger bore unit is more powerful. If you're after power, always go for the bigger master cylinder!

By Staff

Does this unit come with brake switch?

By Skinner

No, there is no brake switch included with this master cylinder, you are to re-use the OEM unit in order to complete the installation. In the event you require a new switch, we have Drag Specialties Front Brake Light Switches available for a wide variety of Harley-Davidson motorcycles that'll also work with this master cylinder.

By Staff

I have a 1974 xlh 1000 Sportster with electric start the two buttons indicate electric start and turn signal you note in your description that stoplight will this application fit my electric start button and my turn signal button

By Anon.

Yes, this XLH1000 front brake master cylinder is designed to work with the stock clamp with start and signal buttons.

By Staff

Does this take a 10m banjo bolt.?

By Derrick w

These Drag Specialties front brake master cylinders accept either, a 7/16"-24 or 3/8"-24 size banjo bolt, depending on what make, year and model machine it is that you select from our drop down fit guide. So long as you're fitting it to one of the models listed that has the stock front brake lines and front master cylinder on it, you should have no problem bolting it up to any machine in our fit guide.
