Harley Front Master Cylinders, Rebuild Kits and Covers
The master cylinder decides how your front brake feels at the lever. Replace a leaking one, rebuild the one you have, or clean up the bars with a new assembly. We stock front master cylinders from Drag Specialties, V-Twin Mfg, Performance Machine, Joker Machine, GMA and Hawg Halters.
Match the Bore to Your Brakes
- 9/16" bore: stock single disc front ends, '96–'17
- 11/16" bore: stock dual disc front ends, '96–'17
- 5/8" and other sizes: in the listings for custom setups
The wrong bore gives you a lever that's rock hard or one that comes back to the grip, so check it before you order.
What's Here
- Complete assemblies: chrome and black, stock style and cut down
- Rebuild kits: by year and bore
- Covers: stock replacement and custom
- Hand lever assemblies: old school master cylinder and lever sets for choppers and bobbers
Finish the front brake with brake lines, brake calipers, brake rotors and levers. For the back, see rear master cylinders, or shop all Harley brakes.
Not Sure It Fits?
Year, bore and single or dual disc all matter, and plenty of master cylinders look the same but aren't. If you can't tell whether something fits your bike, hit us up with your year and model and we'll check it before you order.
