5 Replacement procedure
5.1 General information
The objective of this chapter is to give instruction and
guidance on how the disc brake and/or its compo-
nents should be replaced. The replacement proce-
dures in this chapter require the wheel to be removed
to enable the replacement work to be carried out.
5.2 Replacing the brake pads
5.2.1 Initial procedure
Read and follow chapter
removing the brake pads.
5.2.2 Removing the brake pads
Danger!
Wear respiratory protection in order to avoid inhaling
particles which can be hazardous to health! Brake
pad wear produces dust which can cause lung dam-
age!
●
Sudden release of tensioned springs can cause
injury!
●
Do not actuate the brake when replacing the
brake pads!
●
In addition, ensure that the compressed-air brake
system is pressurised during the replacement
procedure, (min. 6 bar)! If the pressure drops
below 6 bar, the parking brake is actuated auto-
matically.
Caution!
●
Use a vacuum cleaner to clean the surfaces. Do
not use compressed-air.
●
Take care when using chemicals and/or cleaning
tools (e.g. knives, brushes, etc.). This to avoid
damage or displacement of hoses, seals and
other components.
1. If necessary, remove dirt, dust and other possible
debris.
Caution!
●
Where indicated, use SAF-HOLLAND tools only.
●
Never use an impact wrench or similar to rotate
the reset shaft. Doing so could damage the inter-
nal components of the mechanism! The maxi-
mum torque is 20 Nm.
Note:
The thrust plate must be fully retracted to be able to
fit new brake pads.

2. Remove the reset shaft protective plug,
3. Use the Torx 55 socket to manually rotate the reset
shaft anti-clockwise. This de-adjusts the brake so
that the thrust plate fully retracts to its inner posi-
tion. A clicking sound must be heard and felt when
retracting. The inner thrust plate position must be
distinct. The tightening torque must not exceed
20 Nm. The de-adjust position must not be main-
tained. In the de-adjust position, the adjustment
function is overridden.
Caution!
Always ensure the pad retainer spring bracket is fully
held down whilst levering out the pad retainer.
