EAZ Performance Front Brake Caliper Major Rebuild Kit with Pistons & O-Ring Seals for Royal Enfield Classic & Bullet 350/500 UCE

Restore original factory braking bite, eliminate dangerous fluid leaks, and fix sticky brakes with the EAZ Performance Caliper Major Rebuild Kit. Specifically engineered to fit the twin-piston front disc brake assemblies of Royal Enfield UCE (Unit Construction Engine) models, this premium aftermarket kit provides everything needed to completely overhaul your hydraulic front brake caliper.

Over years of heavy commuting and exposure to road salt, dust, and rain, your brake caliper components face massive abuse. Road grit penetrates past weak dust boots, causing the caliper pistons to pit, corrode, and score. This results in sticky pistons that cause heavy brake drag, premature pad wear, reduced fuel economy, or severe fluid leakage.

As clearly shown in the comprehensive product assembly in image_2ce838.png, the EAZ rebuild kit comes packed with high-precision components:

• Dual Hard-Anodized Pistons: Micro-polished, friction-resistant alloy cylinders designed to resist corrosion and slide smoothly within the caliper bores under intense hydraulic pressure.

• Premium Nitrile O-Ring & Dust Seals: Formulated from a special high-density, glycol-resistant rubber compound that provides an airtight, high-pressure seal while acting as an absolute barrier against road moisture and mud.

• Caliper Slide Boots & Bleeder Valve Cap: Durable vulcanized rubber slider boots to isolate moving slide pins alongside an integrated rubber bleeder valve dust cover cap.

• Fresh Fluid Bleeder Valve: A replacement zinc-plated steel bleeder screw to guarantee easy, leak-free brake line bleeding during your overhaul.

Key Performance Features:

• Complete Overhaul Solution: A major rebuild kit containing dual pistons, internal hydraulic fluid seals, external dirt dust seals, pin boots, a fresh bleeder valve, and a protective dust cap as laid out in image_2ce838.png.

• Zero-Leak Hydraulic Engineering: Premium inner seals hold maximum pressure without swelling or hardening, eliminating spongey lever feel caused by internal pressure loss.

• High Thermal Stability: Micro-finished pistons and seals withstand high operating temperatures generated under hard, continuous braking on long downhill tours.

• Direct Drop-In OEM Tolerance Match: Precision-stamped and molded to strictly match ByBre/factory twin-piston caliper dimensions for an exact, hassle-free fit.

Motorcycle Compatibility:

• Royal Enfield Classic Series (UCE Models): Tailor-made for Classic 350 and Classic 500 Unit Construction Engine variants (BS3, BS4, and UCE Dual-Channel ABS BS6 platforms).

• Royal Enfield Bullet & Electra Series (UCE Models): Fully compatible with Bullet 350, Bullet 500, and Electra Twinspark chassis utilizing factory front disc brakes.

• Note: This kit is sized specifically for legacy twin-piston UCE front calipers. Please verify your exact caliper dimensions if trying to adapt this to newer J-Series Reborn models or single-piston rear disc assemblies.

Workshop Installation Tip:

Before installing your fresh components, ensure the entire caliper housing is completely stripped of old jelly-like brake fluid and white oxide corrosion inside the seal grooves using a specialized parts cleaner. Lubricate the new internal O-rings and pistons with a thin film of clean DOT 3 or DOT 4 brake fluid before pressing them carefully into place. Never force the pistons in crooked, as this will permanently tear the precision rubber seals!
