Brake pad spacers

thingiverse

Brake pad spacers for bleeding single-piston Shimano calipers. These are in two parts, because it makes it easier to get them in and out of the calipers without removing the calipers from the frame, plus you can stack them into any thickness you like (10mm is the correct thickness I think, but this way you've got options) Disclaimer: Don't work on your own brakes if you don't know what you're doing, you might die and also you might scratch your bike.
