What This Guide Helps With
Troubleshoot a persistent brake warning by checking brake engagement, caster position, floor conditions, pedals, external linkage, indicators, and repeatability.
Step-by-Step Troubleshooting
1. Protect the Patient From Unintended Bed Movement
A bed with an unreliable brake indication or questionable brake engagement must not be trusted for patient transfer, treatment, or unattended use.
If a patient is in the bed, maintain control of the bed and transfer the patient to another verified bed if brake security cannot be confirmed.
Expected outcome: The patient is protected from unexpected bed movement. If the bed cannot be positively secured, remove it from service immediately.
2. Confirm the Complaint and Actual Brake Condition
Place the bed on a level, clear surface and engage the brake using the normal brake pedal.
Confirm whether:
- The warning remains active.
- The bed is physically prevented from rolling.
- One or more casters still rotate or swivel unexpectedly.
- The warning clears intermittently.
- The warning appears only after bed movement.
Do not rely only on the warning indicator to determine mechanical brake function.
Expected outcome: The actual mechanical brake condition and the warning behavior are separately established.
3. Verify Full Brake Pedal Engagement
Operate the brake pedal through its normal range and confirm it reaches the fully engaged position without obstruction.
Inspect for:
- Linens wrapped around pedals or casters.
- Objects under the bed.
- Equipment contacting the brake pedal.
- Damaged pedal covers.
- A pedal that does not fully travel.
Expected outcome: The brake pedal reaches its intended engaged position freely. If clearing an obstruction allows full engagement and the warning clears, verify all casters and stop troubleshooting.
4. Check Each Caster Mechanically
With the bed unloaded when possible and under controlled conditions, verify the brake condition at each caster.
Gently attempt to move the bed in several directions without excessive force. Observe whether any caster:
- Rolls.
- Swivels unexpectedly.
- Appears partially engaged.
- Is visibly damaged.
- Fails to follow the brake mechanism.
Expected outcome: All required casters lock as intended. If any caster fails to lock, remove the bed from service for mechanical repair rather than treating the condition as only an indicator problem.
5. Inspect the Floor and Caster Contact
Confirm the bed is on a firm, level surface and that each caster is fully contacting the floor.
Check for:
- Thresholds.
- Uneven flooring.
- Debris beneath a wheel.
- Cords or tubing beneath casters.
- Bed components supporting weight instead of a caster.
Expected outcome: All casters have normal floor contact. If repositioning the bed clears the warning and braking remains reliable, repeat the test and stop troubleshooting.
6. Cycle the Brake Mechanism
Release the brake completely, roll the unloaded bed a short controlled distance, and reapply the brake.
Repeat the cycle while observing the warning indicator.
Do not repeatedly operate a visibly damaged mechanism.
Expected outcome: Brake engagement is repeatable and the warning clears when the brake is fully applied. If cycling restores consistent operation, complete additional verification before return to service.
7. Inspect Accessible Brake Linkage and Pedals
Visually inspect the accessible brake/steer pedals, rods, mechanical linkage, and caster interfaces for:
- Bent components.
- Loose hardware.
- Impact damage.
- Misalignment.
- Foreign material.
- Incomplete mechanical travel.
Do not perform deep disassembly of the brake system during initial troubleshooting.
Expected outcome: No external mechanical defect prevents full brake engagement. Visible damage requires removal from service.
8. Compare Warning Behavior With Mechanical Engagement
If all casters are securely locked but the brake-not-set warning remains, document whether the warning changes when the pedal is moved slightly within its normal operating range.
Do not manipulate or bypass switches or sensing devices.
Expected outcome: A persistent warning despite confirmed mechanical brake engagement identifies the problem as likely related to brake-state detection, linkage adjustment, wiring, or another service-level condition.
9. Perform Final Functional Verification
Following any correction, verify:
- Brake engages fully.
- Bed does not roll when appropriately tested.
- Brake releases normally.
- Warning appears when brakes are released if applicable.
- Warning clears consistently when brakes are set.
- Brake operation remains consistent after repositioning the bed.
Expected outcome: Mechanical braking and brake-status indication are both reliable. Troubleshooting can stop once normal function is repeatedly verified.
10. Escalate Persistent or Unreliable Brake Indication
If mechanical engagement is correct but the warning remains, or if caster braking is inconsistent, stop external troubleshooting.
Expected outcome: The bed is removed from service and routed for qualified evaluation of the brake mechanism and brake-status detection system.
If the Problem Persists
Common external causes such as incomplete pedal engagement, caster obstruction, uneven floor contact, debris, and visible linkage interference have been ruled out.
The remaining issue may involve brake linkage adjustment, caster hardware, brake-state sensing, wiring, electronic input processing, or another service-level condition.
The bed should be:
- Removed from service.
- Labeled Out of Service.
- Sent for repair or bench evaluation.
- Evaluated using appropriate Hillrom service documentation and approved test equipment.
- Repaired or adjusted only by qualified personnel.
After repair, verify both physical brake holding and correct warning behavior before returning the bed to service.
Knowing when to stop is particularly important with brake faults because an apparently stationary bed may still be unsafe during patient transfer.
Clinical Use Tip
Never use a brake warning as the sole confirmation that a bed is secure; physically verify the bed cannot roll before patient transfer or other movement-sensitive care.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported that the brake-not-set warning remained active after the brake pedal was placed in the locked position."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found debris beneath one caster preventing full floor contact and complete brake engagement."
Resolution
What action was taken.
Example:
"Removed the debris, repositioned the bed, and verified all casters locked securely and the brake warning cleared consistently through repeated brake cycles."
Helpful Details to Include (If Known)
- Whether the bed physically moved with brakes applied.
- Which caster appeared affected.
- Brake pedal travel.
- Floor condition.
- Debris or obstruction found.
- Visible caster or linkage damage.
- Warning behavior before and after cycling.
- Whether warning was constant or intermittent.
- Results of repeated brake tests.
- Final bed status.
Final Thought
Treat any brake complaint as a patient-movement hazard until both mechanical braking and indication are verified. Rule out simple external causes first, escalate persistent or inconsistent behavior, and document both the physical brake test and warning response.
That is successful troubleshooting.
