Published: 21 September, After washing out with plenty of water, I had to deal to the problem that although things were moving like they should, there was no lubrication. WD40 might have worked for a day, Oil, chain lube etc a bit longer, but what is needed is grease. Fortunately there are aerosol based Grease products that have a thin carrier that are perfect for the job. I "filled" the brifter with aerosol grease and wiped off the excess. The idea too much grease is better than too little - I can clean grease out if needed, but can't put the metal back on the worn out bits In your case, i would look at this approach if you can't find a way to pull them apart and know for certain you will get them back together.

You'll find a screw there. Unscrew it and pull the shifter back to remove it Remove the brake cable pivot pin inside the shifter Pulling the brake will reveal the screws inside the shifter.

I am facing a similar issue If I remember correctly, the spring was bent in half, so I straightened it out and put it back in.
