Ahhh right , so next ,what you do after you've removed the shifters from the levers is to get two bags
Mark one Lh and the other right hand , put the collection of little springs ,pressed parts and washers in the respective bags
Next take a hacksaw /milling machine to the brake levers and remove the shifter mounts
You will now have a perfectly functioning set of xt brake levers
Now the bags containing the shifters , put them in that drawer/old biscuit tin /tupperware box in the shed
And fix them later ,just like the watch strap ,rusty padlock, and the broken plastic toy that you got from the
Christmas cracker 3 years ago
Then buy some thumbies
Here to help
