Royal Enfield 1100729/D – Rear Brake Master Cylinder Assembly (OE) for Meteor 350 BS6 & UK / Euro V

Restore braking reliability with the genuine Royal Enfield 1100729/D Rear Master Cylinder Assembly. As the original equipment (OE) component fitted to the rear brake system of the Meteor 350 UK/Euro V models, this master cylinder meets factory spec for internal bore size, sealing, mounting, and hydraulic performance.

Over time, your rear master cylinder may suffer wear: piston seals degrade, leaks appear, the lever feels spongy or loses responsiveness. Replacing with part 1100729/D ensures you regain crisp braking feel, proper pressure buildup, and safe stopping power. Built from high-grade materials, this cylinder is corrosion resistant and designed to integrate with the standard reservoir, brake line and lever without modification.

Whether you're replacing a worn unit, dealing with a leak, or just doing preventative maintenance, this OE master cylinder delivers the performance and durability expected from Royal Enfield’s braking components. Installation requires basic mechanical skills: removing old unit, transferring lever & reservoir if needed, bleeding system, and ensuring firm pedal feel. Ride safe with the correct spare and avoid potential safety hazards.

FAQs:

1. Is this the genuine Royal Enfield part or aftermarket?
   This is a genuine OEM part. Royal Enfield’s parts catalogues list 1100729/D as “MASTER CYLINDER-REAR”.

2. Will this fit non-UK Meteor 350 or Indian BS6 Meteor 350?
   Yes it fits all Indian Variants.

3. Do I need to reuse the old brake lever or reservoir?
   You can reuse the stock lever and reservoir provided they are undamaged and properly sealed. However, ensure all seals in the master cylinder are good; any damage can compromise performance.

4. How do I bleed this master cylinder after installation?
   After installation, bleed the rear brake line until firm pedal feel. Use the recommended brake fluid (as per your Meteor 350 manual), purge air bubbles from reservoir, lines, and cylinder. Check lever travel and leaks before riding.

5. How do I know it's time to replace the rear master cylinder?
   Common signs: rear brake lever feels spongy even after bleeding; visible fluid leak; lever travel too long; seized piston or sluggish return; hard to modulate braking. If any of these appear, replacement with a genuine unit like 1100729/D is recommended.
