If some "sponginess" is detected on the brake control, due to air bubbles in the system, bleed the system, as indicated in sect. 4 - 3, Changing the brake fluid.
Before bleeding a brake pump, move back the calliper pistons, as indicated in (sect. 4 - 3, Changing the brake fluid) to Drain in the pump the air collected near the abs control unit purge must be carried out by means of the corresponding joints (a) placed near the callipers and the brake pumps.
Important
Do not undo the fixing screws of the joints of the pipes on the abs hydraulic control unit, unless control unit replacement is necessary.
Important
If the abs control unit is replaced, this must be supplied with secondary circuit already full of fluid; the control unit must be fitted and the system filled and bleeded as a traditional system.

Source of emissions
The combustion process produces carbon monoxide and
hydrocarbons. Control of hydrocarbons is very important
because under certain conditions, they react to form
photochemical smog when subjected to sunlight.
Carbon monoxide does not react in the same way, but is
toxic. Duca ...
