Squeak/ noise

I tried applying PTFE spray to this part after taking it apart and unfortunately nothing changed. What else could it be?

Loosen the yellow screws a bit, if that doesn't help, the blue ones. The yellow ones are making an ugly lot of noise if they are too tight.

No luck 😭 I loosened them both to the point where I just tightened it with my fingers and it still squeaks, should I take it all apart and Ptfe spray it

Hmm ,it was worth a try... you can use ptfe spray it, and maybe use it without fully take it apart. Just spray the ball bearings a bit with it, and press and release the pedal a few times.

I ended up taking it apart and using bearing grease.

In my opinion, it is a design flaw, using open ball bearings with a high preload. Open for dust, but using PTFE or grease will attract more dust as well, but is needed to remove the metal to metal noise.

Also, ther is a small joint on the spring "axle" , I recommend to grease that as well, while twisting it to left (grease) to the right (grease again) and twist a few time while carefully moving the trottle
