The brake/steer caster is located at the left-hand foot end of the base frame. The other three
casters are brake casters. To service the central braking system mechanism, lay the bed on its
side. Before you do this, you must disable the siderail and remove the brake/steer pedal.
Removal

2. Disable the siderail: lower it beneath the bed and tie it in this position, or
remove it as an assembly from the bed (refer to procedure 4.27).
3. Place the brake/steer pedal (A) into the steer position (see figure 4-43 on
page 4-87).
4. Remove the two screws (B) that attach the leg covers (C) to the bed (D).
5. Remove the leg covers (C).
6. Remove the foot-end rocker arm (E) as follows:
