Check hydraulic clutch control

Note
If the master cylinder and/or slave cylinder must be replaced
♦
due to the predetermined fault, first of all check the hydraulic
clutch control.
If the slave cylinder with the connected tube-hose line is re‐
♦
moved from the gearbox, do no longer depress the clutch
pedal. Otherwise, the piston can be pressed out of the slave
cylinder and thus be destroyed.
The clutch hydraulic is connected to one of the chambers
♦
-arrow 2- of the brake fluid reservoir by the return hose
-arrow 1-.
If there is little or no brake fluid in this chamber, there is a leak
♦
in the system.
Traces of brake fluid on or below the gearbox, as well as on
♦
the noise insulation under the gearbox is a result, amongst
others, of an external leak.
In case of leakage, the corresponding component must be re‐
♦
placed ⇒ Electronic Catalogue of Original Parts .
Check the correct routing of the tube-hose line between the
♦
master and slave cylinder. The line must not be kinked or trap‐
ped.
The brake pedal return must not be obstructed by moved or
♦
additional covers (floor coverings).
Inspect the complete hydraulic system for leaks.
– Carry out a visual inspection of the following components of
the hydraulic clutch control for leaks:
♦ Check brake fluid level in the brake fluid reservoir.
♦ Return hose between brake fluid reservoir and master cylin‐
der.
♦ Master cylinder.
♦ Tube-hose line between master cylinder and slave cylinder.
♦ Connection points (plug and screw connections) also in a non-
visible area.
♦ Slave cylinder.
– Remove the slave cylinder (do not open the line system) and
check if no brake fluid drips out of the bellows, to do so remove
the bellows from the rod -arrow-.
– If necessary, bleed the clutch control
– Then depress the clutch pedal carefully, at the same time hold
the pedal in five different positions for approx. 20s over the
entire distance the pedal has to travel and check that the pedal
does not fall through on its own while being held (in five posi‐
tions). While doing so, a second mechanic must check if fluid
is leaking from the other components of the hydraulic clutch
control ⇒ page 57 .
