YZF-R1M brake caliper how-to guide

An almost life-size YZF-R1M brake caliper made by needle felting. Go ahead and take up the challenge!

Let's try making a brake caliper by needle felting.

It is the brake caliper which adjusts a bike’s speed enclosing the disc plate that is attached to the wheel that spins at high speed with disc pads.
We have completely reproduced an almost life-size brake caliper mounted on the YZF-R1M! It is almost life-size and made of felt!
Why don’t you take up the challenge and make it according to the pattern and the how-to videos?

Introduction

Check the finished firmness

As you poke the needle into the wool, it becomes more and more firm. You may wonder how firm you need to make the wool.
The firmness of the 1.8cm ball made from 1g of wool as shown in the felt ball how-to guide in the Basic Needle Felting Lesson is the standard firmness for making the YZF-R1M brake caliper.
If the felt is not firm enough, it will be off-kilter when assembling or the finished item will fall apart so it is important to work the felt to make it firm.
