The resource of the original pad for Lachetti is 30,000 km on average. The number may vary according to the driving style-frequent heavy braking can reduce the resource of the headpiece by half.
There are no features in the procedure to replace the Lachetti's. For this operation, you will need a 14-tool key and a tool to crush the piston of the cylinder inside (for example, a tire iron). It is recommended that the piston be pressed through a gasket (an old brake pad suitable) to avoid piston bias.
