Symptoms
- Stroller rolls even when the brake lever is pressed down
- Brake pedal feels loose or doesn't click into place
- Brake works on one side but not the other
- Grinding or clicking sound when trying to engage the brake
Likely causes
- CommonDebris blocking the brake pin or notchDirt, small rocks, or grass can prevent the brake pin from seating into its locking notch on the wheel.
- CommonBrake linkage misaligned or bentThe bar connecting the pedal to the pin on each wheel can bend slightly or shift out of alignment.
- PossibleWorn brake pin or notch on the wheelRepeated use over time can round off the edges of the pin or notch, reducing how well they lock together.
- PossibleOne-sided engagement on dual-wheel brakesSome strollers need the brake to engage both rear wheels evenly, and one side can be slightly misaligned.
- PossibleRust or corrosion on the pin from moisture exposureWet or winter conditions can corrode the small brake pin so it doesn't slide freely.
What to do
- Turn the stroller over or tilt it back to see the brake mechanism near the rear wheels clearly.
- Press the brake pedal and watch whether the pin moves and lines up with the notch on the wheel; clean out any visible dirt or debris with a brush.
- Spin the wheel slowly while pressing the brake to find the exact point where the pin should catch the notch.
- Check that the linkage bar between pedals (on strollers with one brake pedal for both wheels) isn't bent or disconnected.
- Apply a small amount of lubricant to the pin's sliding mechanism if it looks corroded or moves stiffly.
- Adjust or re-bend a slightly misaligned linkage gently if you're comfortable doing so, or tighten any loose linkage screws.
- Test the brake on a slight incline in a safe area, holding the handle, before relying on it fully.
Tools and parts
- Small brush
- Lubricant (light machine oil or silicone spray)

When to call a pro
If cleaning and lubricating don't restore reliable braking, or the pin/notch looks worn down, contact the manufacturer for a replacement part or have a stroller repair service look at it.
Safety
Use caution
Never rely on a stroller with a brake you haven't confirmed holds firmly, especially near stairs, curbs, or slopes; always keep a hand on the stroller until it's tested.
