Once washed, the parts must be dried with jets of compressed air; afterwards, make sure that:
- That the pump body does not show signs of internal damage or corrosion as this may result in sealing
ring or piston failure; the latter must also be replaced if worn or scratched or if mating with the cylinder
has a clearance higher than that prescribed in the specific section "Fitting clearances."
- That the rubber parts in the piston and the valve are not dilated or damaged as this most likely leads
to poor braking.
- That the piston return spring is in good condition.
