Jiataban 9/16" Front Brake Master Cylinder Rebuild Kit for Harley 1996–2017 — 9/16" Bore, OEM #45006-96/96c, Full Seal & Piston Se

Jiataban's 9/16" front brake master cylinder rebuild kit is a complete replacement set of rubber, aluminum, and steel components designed to restore the front master cylinder performance on compatible Harley single-disc models (OEM #45006-96/96c).

If your Harley’s front brake lever feels spongy, leaks fluid, or has lost firm engagement, a worn master cylinder rebuild kit is often the fix. This Jiataban kit contains the seals, pistons, springs, and metal components specified for 9/16" bore front master cylinders on many 1996–2017 single-disc Harley models. It’s engineered to match OEM fitment so you can rebuild rather than replace the entire master cylinder, saving cost and preserving original components.

Which Harley models and years will this kit fit?

This rebuild kit is intended for Harley single-disc front brake applications with a 9/16" bore and replaces OEM part 45006-96/96c. It covers many Touring, Softail, Dyna, and Sportster variants produced from the mid-1990s through 2017, with specific exceptions noted.

• Fits 1996–2017 single-disc models with 9/16" front bore (excludes 2015–2017 Softail and 2004–2017 XL where specified).
• Compatible with models such as Electra Glide, Road King, Street Glide, Dyna, Softail, and many Sportster variants within the listed years.
• Replaces OEM #45006-96/96c for a direct-fit rebuild approach.

What parts are included and what materials are used?

The kit contains the internal components needed to rebuild the front master cylinder for a 9/16" bore. Jiataban uses common rebuild materials to balance durability and sealing performance without forcing replacement of the entire master assembly.

• Seals, O-rings, and dust boots molded from brake-grade rubber for fluid resistance.
• Pistons, springs, and metal inserts manufactured from aluminum and steel for structural strength.
• One complete set per package—everything required to rebuild the front master cylinder internals.

How will installing this kit affect braking performance?

Replacing aged seals and pistons restores proper hydraulic pressure and lever feel without altering the braking system design. The result is firmer lever engagement and improved hydraulic response when the master cylinder components are degraded.

• Eliminates leaks and reduces internal bypassing caused by worn seals.
• Restores consistent lever travel and hydraulic pressure under normal riding conditions.
• Preserves original master cylinder housing, lowering replacement costs.

What should I know before attempting the rebuild?

Master cylinder rebuilds require basic mechanical skills, proper tools, and attention to brake-fluid cleanliness. If you’re unsure, have a shop perform the rebuild to ensure correct assembly and safe brake bleed procedures.

• Use the correct 9/16" bore master cylinder service procedure and torque specs for your model.
• Keep brake fluid and work area clean; flush and bleed the system after reassembly.
• Verify compatibility with your specific model year against the provided fitment list before purchase.

Who is this for? Riders and mechanics who own compatible Harley single-disc models and want a cost-effective, OEM-replacement-style solution to worn master cylinder internals will benefit most. This kit is aimed at owners who prefer rebuilding the original master cylinder to maintain factory hardware, reduce parts cost, and restore dependable lever feel—provided they follow proper installation and brake-bleeding procedures.
