Frequently Asked Questions

What is included with Honda brake-caliper piston 45107-413-003?

One Japanese-made caliper piston replacing Honda OEM 45107-413-003 is included. The piston seal, dust seal, brake pads and hydraulic fluid are not included.

What should be inspected before installing a new caliper piston?

Check the caliper bore, seal grooves and piston for corrosion or scoring and replace the correct seals. A damaged bore can leak or bind even with a new piston.

Does the brake system require bleeding after piston replacement?

Yes. Assemble with brake-compatible lubricant and the seals specified for the caliper, fill with the Honda-specified brake fluid and bleed all air. Verify free wheel rotation, firm lever pressure and no leakage before riding.
