Important fitment notes

• For Triumph Bonneville & T100 2002–2008 carburettor models with the original front brake reservoir shown in the listing drawing.
• Check the exact model and original components before installation. Aftermarket or modified assemblies may require different hardware.

• Photographs illustrate the hardware and fitting positions. The contents table defines the actual supplied quantities.

Model-specific aftermarket replacements

Biker Bling selects these replacements for the listed original fixing positions. The Triumph references identify the original components replaced, not Biker Bling product codes. These are aftermarket replacement parts, not genuine Triumph-branded components.

Materials and appearance: The supplied bolts are stainless steel. Their appearance may differ from the originals. Material alone does not establish equivalent mechanical strength.

When should you replace these fixings?

• Corroded cap bolts: Inspect marked or corroded heads before removing the lid.
• Damaged drive recesses or threads: Replace damaged hardware and inspect the reservoir mounting threads.
• Missing cap fixings: Restore the correct pair so the cap is retained as intended.

New bolts cannot repair a cracked reservoir, distorted cap or damaged diaphragm. Investigate leaks rather than simply tightening the cap further.

Fitting information

Keep dirt and moisture out of the open reservoir and protect painted surfaces from brake-fluid spills. Seat the diaphragm and cap as Triumph specifies, then follow the workshop procedure for tightening and thread condition. Use anti-seize only where appropriate for that fixing. Before riding, confirm the cap is correctly seated and secure, inspect for leaks and check normal brake operation. Have contaminated fluid or damaged hydraulic components checked by a qualified motorcycle technician.

For general guidance, read our stainless steel motorcycle bolt fitting guide. Triumph’s workshop procedure takes precedence.
