Need help with stuck lock mechanism for pram

Wouldy

 Hi. 

I'm fixing this pram for a young mum. I've identified the issue. The two front wheels are having unlocking/locking issues. I've taken it apart for both front wheels. The issue is the lock mechanism when pushed up and down will not lock in. 

I took it apart, have given it a good clean up and grease. I think for some reason I cannot see the lock is jamming. First photo is in the up position which is unlocked. Second photo is in the down position which is locked. Third photo you can see the little black button poking out which shows it is in lock position. 

The trouble is, there is difficulty getting the lock to go up and down smoothly. Pushing down, pushing up action is prevented. I'm not sure what could be causing it without trying to open it further. There is a pin I would have to slowly weasel apart to remove it so I can go further. 

Does anybody be have any ideas?

Hi @Wouldy,

Do both the front wheels have locking mechanisms on them, independent of each other, and they've both failed? My first thought is whether you are putting enough force on them to lock. With my child's stroller, you can push the lever down, but it requires an additional solid movement with your body weight to lock it into place. On mine, I couldn't operate the lock with enough force by hand. Have you tried reassembling and activating them with your foot as I presume they were designed to be?

I'd imagine if it is not a case of them being activated correctly, it would be because something has jammed or broken inside. You'll need to take them apart further to diagnose that.

Please also take care as a brake mechanism on a stroller must work correctly at all times and for it to fail whilst in use could have dire consequences.
