3.16 REMOVING AND INSTALLING BELLOWS WITH BRAKE CALLIPER THRUST 

PIECE, KNORR SB7000 VERSION

Removing bellows with SB7000 brake calliper 
thrust piece
1.

Using the hexagonal adjusting bolt, unscrew 

the thrust pieces as far as is necessary to 

gain access to the bellows.

Note:

Unscrew the thrust pieces a maximum of 

30 mm. Do not screw them completely out of 

the brake calliper, as the brake calliper 

assembly would then have to be replaced.

Note:

Never turn the hexagonal adjusting bolt 

without using an adapter. The adapter is a 

torque safety and will break off when the 

torque is too high. Without the use of an 

adapter the mechanics in the brake calliper 

may become damaged when the torque is 

too high, so that replacement of the brake 

calliper may be necessary.

2.

Using a screwdriver, ease the bellows 

behind the thrust piece out of the brake 

calliper.

Note:

Do not insert the screwdriver too deeply into 

the brake calliper. This could damage the 

seat of the inner seal of the thrust pieces. 

These cannot be replaced and the brake 

calliper would then have to be replaced.

3.

Press the thrust pieces (13) off the adjusters 

with the disassembly fork (A), special tool set 

(DAF no. 1329494).

4.

Remove the bearing bushes (161) from the 

thrust pieces.

Fitting bellows

Note:

Do not screw the adjusters entirely out of the 

brake calliper, as the entire brake calliper 

would then have to be replaced.

1.

Check the screw thread in the adjusters.

2.

Grease the screw thread of the adjusters. 

See "Technical data".

3.

Screw the adjusters back into the brake 

calliper.

4.

Fit new bearing bushes (161) on the 

adjusters.

5.

Fit the thrust pieces and bellows (13) on the 

adjusters.

6.

Using the pressure tool and a pin from the 

special tool set (DAF no. 1329494) (B), 

press the bellows into its seat.

7.

Turn the pressure tool (B) round and press 

the thrust pieces (13) onto the adjusters.

Note:

The operations described above can also be 

performed if the brake calliper has been 

removed. In that case an additional pin (8) from 

the special tool set (DAF no. 1329494) must be 

used, since the brake disc cannot be used for 

support.

Note:

Do not insert the screwdriver (3) too deeply 

into the brake calliper. This could damage 

the seat (6) of the inner seal (5) of the thrust 

pieces. These cannot be replaced and the 

brake calliper would then have to be 

replaced.

3.

Press the thrust pieces (2) off the adjusters 

with the disassembly fork (3), special tool set 

(DAF no. 1329495).

4.

Remove the bearing bushes (4) from the 

thrust pieces.

Note:

If the bellows of the thrust piece is replaced, 

the inner seal must also always be replaced.

5.

Place a brake pad in the brake calliper on the 

outside so that the adjusters cannot be 

screwed out of the brake calliper at the next 

check. Place a 70-mm-thick spacer (self-

made) if the brake calliper has been 

removed from the axle.

6.

Screw the adjuster about 30 mm out of the 

brake calliper and check the thread of the 

adjuster for dirt, corrosion and damage.

7.

Screw the adjuster all the way back into the 

brake calliper.

8.

Using a screwdriver, ease the inner seal out 

of the brake calliper.
