• This kit contains an M9 adjustment screw nut and an M8 nut.
• Kit sold with a strong Ø 38mm square gasket and a weak Ø 38mm gasket.
• The supply of these two seals allows you to install the most suitable seal depending on the wear of the caliper grooves.
• To identify a caliper with a square or round seal, refer to the symbol indicated on the caliper casting.
• A square symbol indicates a square seal, while a circle symbol indicates a round seal.
• It is essential to replace the same type of seal (round or square) according to the symbol on the caliper.
• We recommend checking the symbol displayed on each caliper, as a vehicle may have Calipers of different origins, some of which may have square joints and others round joints.
• It is not recommended to mix calipers on the same set, as this can lead to the risk of skewing during braking.
