Titanium Disc Brake Caliper Bolts
That's right: using the same TiN vapor deposition and anodizing process as those fancy drill bits at the hardware store we've built light-but-strong titanium brake caliper mounting bolts to coordinate with our brake and shift lever kits.
The tapered head saves weight while retaining strength, and the captive washer makes caliper adjustment easier. We used a smaller 4mm hex to increase head strength and reduce the temptation to damage your frame or fork by over-torquing your hardware.
They'll save multiple grams over stock steel bolts... but it's OK just to like how they look.
Multiple sizes are available:
- M6x16 is intended for mounting calipers directly to frames, forks, and threaded adapters. Not for use with unthreaded adapters or spherical washers (usually used to allow upsized rotors).
M6 hardware is typically found on post-mount (not flat-mount) mountain bike frames and forks. If your existing caliper hardware measures 6mm across the threads this is the right thread size.
These bolts hold your brakes on. Use care when installing, do not over-torque, and check monthly.
Required tools & supplies:
- Bicycle workstand
- Clean rag
- 5mm hex wrench
- T25 Torx wrench
- 4mm hex wrench
- Torque wrench with
- 4mm hex bit
- Copper anti-seize
- Take care not to touch disc rotors during installation or adjustment. Contamination from oils, greases, or cleaners can lead to noisy or dangerously reduced braking.
- Remove your existing caliper bolts using a 4mm hex, 5mm hex, or T25 Torx wrench.
- Wipe brake caliper mounts and brake caliper with a clean cloth
- Do not spray caliper or anything near the rotor with a cleaner
- Add a small amount of copper anti-seize to the leading threads of the titanium caliper bolts.
- Install titanium caliper bolts through caliper and in to frame or fork. If you encounter resistance stop, realign hardware with holes and try again. It's hard to cross-thread M6 hardware... but even harder to fix.
- Adjust caliper so that pads are visually centered over rotor and snug with a 4mm hex wrench
- Spin wheel and listen for rubbing between the pads and rotor. Re-adjust caliper as needed to eliminate (or at least minimize) pad-to-rotor contact.
- Use a torque wrench and 4mm hex bit to tighten caliper bolts to 7-8Nm.
- Go for a ride.
