Front brake Lever felt jammed..

Rode about 50Kms today without any issues.

Took the bike out again in the evening, pressed the front brake and the lever seemed stuck.
After the first click it didn't go in any further and the bike did not stop. Luckily I was super slow and just used the rear brake. Switched it off and had no idea what had happened.

Tried rolling it forward & pressed the front lever to stop but the same thing happened. The lever just got stuck after the click. No braking. Second time it worked. Rode it back home worried it might happen again but no issues.

Anyone know what might have happened? What could cause the brake lever to act like its stuck? It felt like there was something in-between the lever and the bar. Never happened before..
Bikes about 2 years old and with the regular services.

Wouldn't want this to happen on open roads
Any help would be great!

Thanks!

No, I thought that too, but it's correct in place.

Did you replace the front brake lever, or have it off? If so, we have had reports of people not getting those things on correct and they cause the front lever to jam like that.

Another thing to check is to remove that lever and see if you got a bug stuck in there?

I haven't changed the lever but have taken the full assembly off a few times to change the handlebars.
Will try removing the lever to see if anything is actually stuck inside.

I'll be so pissed if there is actually a bug in there lol

Thanks!

It does sound like the lever itself is getting stuck before it starts pressing against the piston to activate the brakes. The click you're hearing is just the rear light coming on which is just before the lever hits the piston. My guess would be something stuck between the lever and the housing, especially as it cleared itself after a few tries. Taking the lever off is a doddle as it's simply one locking nut and then unscrewing the bolt on the top of the housing. Be careful of the brake switch when refitting.

Ya, my money says a bit of sand or other grit got in there. Take it apart, clean it all up with WD40, grease the contact points and rotation bits and reassemble. Go riding to gain confidence you've got it back to normal.

Thanks guys!
I got it off and gave it a nice cleaning. Had some black mucky stuff on the contacting bits..No idea if that caused the issue..
But seems to be working OK now.
Also I had no idea how easy it was to remove the lever! & found the the little switch that makes the click sound

Thanks again! Cheers!

Kewl! I just had an issue with the brake light not activating from the front lever (was fine from the foot brake). So I took the switch off the casing (one phillips head screw and two electrical terminals) and gave all the innards a good WD-40 treatment followed by a mieral-oil/linseed oil based anti-corrosion spray that claims it's great for electrical fittings as well (AD-2000?).
While messing about I decided to open the left hand side two shell halves (only two phillips head bolts) to access the starter button and kill switches. Managed to pull the innards apart and hit them with similar products...there was evidence of black carbon build up on these two. Came right off. Also found some kind of bug egg/nest in one of the cervices. It didn't like being sprayed and came out easily afterwards ;0

Original issue now banished!

I don't know if anybody else feels like me, but I'm not happy with this. I don't know what went wrong, but I feel a certain unease about the whole thing.

Knowing how simple the mechanism lever to master cylinder piston is, I can't see a bit of dirt actually preventing the brake from working altogether.

Pattu has forgotten to mention that he fitted some clip-on bars a few months ago, by the way.
