Use the special tool (DAF no. 0694794) 
for removing the brake camshaft. Determine 
the correct set of wedges for each bearing 
bush, and fit them on the puller.

Move the loose wedge (1) back so that the 
halves of the pulling piece (2), which are kept 
together by the O-ring, are joined.

Place the puller in the brake cylinder bracket, 
so that shoulder (a) is behind the bearing 
bush. When working on the front axle, 
ensure that the shoulder engages with the 
recess between the bearing bush and the 
brake cylinder bracket.
