Reproduction front or rear brake caliper rebuild kit for the Yamaha models listed. Replace the piston seal when replacing your piston or after cleaning the stock piston. Forms a tight seal to prevent brake fluid from seeping past the piston.
Note: Some models changed brake calipers during their production run, double check the fitment list and piston dimensions.
Kit Includes:
Piston x1: 1L9-25810-03-00 - Diameter 38mm / Height 41mm
Piston Seal x1
Piston Dust Seal x1
Dust Seal Clip x1
Bleeder Cap x1
Installation Tips:
Make sure to thoroughly clean the channel in the caliper that holds the seal, if there is any built up grease or dirt it will not allow the seal to sit properly which will affect the pistons ability to engage and retract.
The darker side of the piston with the indented ridge faces the brake pad.
Use brake grease between the piston and the pad but do not allow any grease or brake fluid to come in contact with brake pads. (this kit does not come with pads)
