Authorized Bajaj Service Centers: The most reliable source; ask for the parts by the numbers above.
Official Spares Distributors: Look for shops with the "Bajaj Genuine Parts" signage.
Online: Reputable platforms like 99rpm or Safexbikes list these individual components under the "Brake Hydraulics" or "Master Cylinder" categories.
Pro Tip: If you are replacing a banjo bolt because of a leak, always replace the copper washers. They are "one-time use" components because they deform to create the seal.
