Working on your brake but the caliper bolts look old and worn out?
These bolts are worked on often and can become damaged. They could be replaced with shiny Titanium hardware!
 
As a general rule, Ti is 45-47% lighter weight than steel bolts.
 
These M8 bolts are made from high-quality hot-forged Ti-6AL-4V for a durable and extremely lightweight bolt. The head size key is 10mm.
 
Note: Please learn about the must-do when using Titanium fasteners. You must use a quality anti-seize compound!
