Royal Enfield Rear Brake Caliper Assembly for Hunter 350 (BS6) – RAB00963/B (Rear Disc Caliper, Non-Brembo Logo Type)

The Royal Enfield RAB00963/B Rear Caliper Assembly is the complete rear disc brake caliper unit used on the Hunter 350 (BS6) rear brake system. If your rear brake feels weak, the piston is sticking, the caliper is leaking, or the slider pins are seized, replacing the full caliper assembly restores correct braking performance and helps prevent uneven pad wear and rotor damage.

This is the correct choice when you need a direct-fit rear caliper replacement instead of rebuilding a heavily corroded or damaged unit. It’s commonly searched as “Hunter 350 rear brake caliper,” “rear disc caliper Hunter,” “rear caliper assembly RE,” “rear brake caliper body,” and “ABS rear caliper Hunter 350.”

Before you buy: Confirm it’s REAR (not front), and match the caliper type (branding/logo style) + mounting/banjo orientation with your existing caliper photo.

FAQs 

Q1 (Fitment): How do I confirm this caliper fits my Hunter 350?
Match part number RAB00963/B and verify by photo: rear caliper shape, mounting ears, brake hose/banjo angle, and branding/logo style. If unsure, share a clear photo of your existing rear caliper.

Confirmed for Hunter 350 (BS6) rear disc setup. If your bike has a different rear caliper branding/type, confirm by old part number or photo before ordering.
