Peugeot/Citroen/DS/Opel 38mm rear calliper cilinder assembling tool / sleeve

Introduction

Yeah, I know. You are not as stupid as me by pressing the brake pedal when the calliper was not mounted. And that's not the reason the cilinder came out of it, right? But still, you do have the same problem: you need to get the cilinder back in…

Yesterday was a bad day, today is a good one.

Sleeve to the rescue

• Print this sleeve in ABS, or alternatively PETG
• Print it with a 0.4 nozzle, other sizes may also work
• Put then sleeve in the opening of the rubber seal in the calliper
• Put the cilinder in the sleeve
• Get the sleeve out

It's a bit of fiddling and you'll need to rotate a bit, but I got it in in a few minutes. It works best if you completely remove the calliper from the car. Also make sure you have removed the automatic brake motor.

• Then rotate it clockwise until the cilinder was completely in and the rubber is completely fitted
  • The first part I needed to rotate, but halfway I could just press it
• If you have difficulties fitting the last part of the rubber, use an airgun in the bleeding nipple opening or in the hose attachment opening
