Works great with plenty of clearance

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?

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

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!

Does this unit come in chrome

It all depends on which model you have. Drag only offers master cylinders in chrome for the earlier Shovelhead models. Once you get to 82' for the Electra glides they start to offer satin black options. You will have a choice of chrome or satin black if it is offered in black for your particular model.

By Staff

Does this unit come with brake switch?

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.

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

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.?

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.
