Brake Pad Replacement

6.2 Fitting of Brake Pads Inboard brake pad
Pads must be changed as an axle set and NOT
individually. Use only pads which are permitted by 1
the vehicle manufacturer, axle manufacturer and
disc brake manufacturer. Failure to comply with this
will invalidate any Knorr-Bremse warranty.

6.2.1. Clean the brake pad bay area.

Before inserting the brake pads, fully wind back the
tappet and boot assemblies (13) by rotating the
shear adapter (61) in an anti-clockwise direction
(see Section 5.2).

Note: If in-pad wear indicators are necessary, this section 6.2.2a - Insert inboard brake pad (SK7)
should be followed in conjunction with section 6.3.

6.2.2. Insert the brake pads (12) as follows:
Outboard brake pad
For SK7 disc brakes the geometry of the brake pads (12)
requires the following fitting procedure:
- Slide caliper (1) inboard and insert inner brake pad (12 )
1
(see Fig. 6.2.2a)
12 2
- Slide caliper (1) outboard and insert outer brake pad (12 )
2
(see Fig. 6.2.2b)
For SN6 and SN7 disc brakes there is no special fitting
order for the brake pads (12), therefore the inboard or
outboard pad can be fitted first.

6.2.3. Turn the shear adapter (61) clockwise until the
pads come into contact with the disc. Do not overwind
the adjuster. Then turn back the adjuster three clicks and 6.2.2b - Insert outboard brake pad (SK7)
check the running clearance (see Section 5.2) .

6.2.4. After fitting the pad retainer (11) into the groove of 1
the caliper (1), it must be depressed to enable the insertion
of the pad retainer pin (44) (only use new parts) (see Fig.).
