Restore your front caliper’s performance with the genuine Royal Enfield KAB00215/A Piston Kit, designed specifically for J-Series 350 motorcycles including the Classic 350 Reborn, Meteor 350, and New Bullet 350. This kit replaces worn or damaged pistons inside your front brake caliper, ensuring smooth braking, even pad pressure, and avoiding seizing or dragging.
Over time, caliper pistons suffer from corrosion, pitting, swelling, or damage — leading to weak braking response or stuck pads. Installing this OEM kit restores factory seal integrity and piston dimensions.
Clean assembly, correct lubrication, and precise installation are essential so the new pistons slide freely within their bores. Always check your old piston size (if stamped) and caliper bore condition before installing.
⚠️ Important: This kit is for front caliper use only. Rear caliper uses a different piston specification. Always match part numbers and piston diameters before ordering.

FAQs:
What does a caliper piston kit include? → Pistons, seals, O-rings and sometimes dust boots required to rebuild the front caliper piston mechanism.
How do I know if I need it? → Symptoms: sticking or slow braking response, uneven pad wear, leaking caliper, or pad dragging.
Does this kit fit the rear caliper too? → ❌ No — this is for front caliper only. Rear pistons are different.
Can I use it on older UCE models? → ❌ Only confirmed for J-Series 350 (Reborn, Meteor, Bullet 350) when their front calipers match this kit.
Any recommendations for installation? → Clean piston bores, inspect for corrosion, use correct brake fluid and bleed air carefully for optimal braking.
