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.
