Take your rebuild a step further with our Master & Slave Cylinder "Plus" Kits. Unlike standard kits that only replace the soft parts, we’ve included a brand-new Clutch Slave Piston to ensure your clutch feels as smooth as the day it rolled off the assembly line.

The Critical Upgrade: Why a New Piston? While seals fail first, the slave cylinder piston is the "muscle" of the system. Over time, heat cycles and grit can cause the original piston to develop:

• Surface Pitting: Microscopic "scuffs" that act like sandpaper on your new seals, causing them to fail prematurely.
• Sticking: Build-up of old fluid and oxidation can cause the piston to hang up, leading to a "lazy" clutch lever or poor engagement.
• Heat Distortion: Heavy use can affect the tolerances of older pistons, leading to pressure loss.

By replacing the piston along with the seals, you eliminate the #1 cause of "leaking-again-next-month" syndrome.

Everything You Get in the Box: This is our most comprehensive kit, designed for a total hydraulic refresh.

• Precision Seals: High-quality EPDM rubber seals resistant to the corrosive effects of brake fluid (DOT 4/5.1).
• New Slave Piston: Precision-machined for smooth travel and perfect seal mating.
• Return Springs: New, heat-treated springs to ensure the piston returns quickly and smoothly every time you pull the lever.
• Copper Crush Washers: Essential for a leak-free seal at the banjo bolt connections. Never reuse old washers!
• Red Rubber Grease: We include a sachet of specialized grease to lubricate the seals during assembly, preventing "dry start" damage and ensuring a smooth stroke from mile one.

The Results:

• Effortless Shifting: Smoother piston travel means less effort at the lever and easier gear transitions.
• Zero Drag: Ensures the clutch fully disengages, making it easy to find neutral at stoplights.
• Maximum Lifespan: A new piston creates a perfect sealing surface, drastically extending the life of your new rubber components.

Installation Note: Even with a new piston, always inspect the internal walls of your slave cylinder body. Use the included Red Rubber Grease liberally on the piston sides and seals during assembly to prevent any "dry" friction during the first few pumps.

Important Safety Disclaimer - Brake Parts Fitment Installation: Before purchase or installation, it is your responsibility to confirm that your bike model is listed in the product fitment table. Incorrect fitment can cause serious safety risks. If you're unsure or need a hand, we're here to help - just reach out and we'll gladly assist you in confirming compatibility.

Brake components are critical to safety and must be installed by a certified mechanic. Improper installation can lead to brake failure, injury, or death. By purchasing, you accept full responsibility. While we are always happy to support you with guidance, we cannot be held liable for any issues resulting from incorrect installation or use.
