Maintaining your rollator brakes is essential for your safety and stability, especially when you need to use the device as a seat. Over time, cables can stretch or components can wear down, leading to unresponsive or loose brakes.
Here is a guide on how to troubleshoot and fix common rollator brake issues.
1. Identify Your Brake System
Before starting, determine which system your walker uses:
-
- Cable Brakes: Most common; uses thin cables that run from the hand levers to the rear wheels.
- Pressure Brakes: Less common; uses a brake bar or rubber tips that apply pressure directly when downward weight is applied.
2. Tightening Loose Brakes
If your brakes don’t engage properly or take too long to stop, the cables may be loose.
-
- Adjust at the Handles: Locate the knurled adjustment knob or tension screw where the cable meets the handle. On many models, turning this clockwise increases tension. Some brands, like NOVA, may require turning the tension screw counter-clockwise to move the brake shoe closer to the wheel.
- Lower Cable Adjustment: If handle adjustments aren’t enough, find the second adjustment mechanism near the rear wheels. Use a wrench or pliers to turn the adjustment nut until the brakes hold securely.
- Check for Gap: A properly adjusted brake should have about 1 mm of space between the brake pad and the wheel when not engaged.
3. Fixing Brakes That Won’t Lock
If the hand levers don’t click into a locked position:
-
- Remove Slack: Loosen the cable locking screw at the brake shoe. Pull the cable tight with pliers while pushing down on the brake shoe, then re-tighten the screw.
- Secure the Lock Nut: Many adjusters have a lock nut. Once you find the right tension, tighten the lock nut against the housing to prevent the adjustment from slipping.
4. Troubleshooting Common Problems
-
- Brakes are Too Tight: If the wheels are hard to move even when the brakes aren’t applied, turn the adjustment knobs in the opposite direction (typically counter-clockwise) to loosen tension.
- Squeaky Brakes: This often indicates a lack of lubrication. Apply a few drops of all-purpose lubricant to the moving parts of the brakes as recommended by your manufacturer.
- Uneven Braking: If one side stops faster than the other, check if the brakes are aligned in the same direction and adjust the tension screws on both sides to match.
5. When to Replace Parts
Standard adjustments won’t help if the hardware is physically damaged. You may need a replacement if:
-
- The brake cable has snapped or is severely frayed.
- Brake pads or rubber tips are worn thin and no longer grip the tire.
- The hand brake levers or internal locking cams have failed.
Safety Note: Always test your brakes after any adjustment before using the walker. If you notice unusual noises or if the brakes still feel loose after trying these steps, consult a professional for repair.
