Hello! I was replacing my front pads yesterday. While working on the right pads, the spring that pushes the back of the pads for tension fell down as I was fitting in the new pads. I removed the assembly from the mounting to hopefully have an easy access to put back the spring but it just wont stay in place. I spent a long time already desperately trying to put bac the spring! I have no idea how it is fitted in! So I installed back the assembly and installed the pads without the spring. Has anyone done this?
