Yes, we completed the job, but the back caliphers were really difficult. Also, wasn't able to put a wire spring (coil) back in place on the passenger rear, which I believe servers the emergency brake. What is the special tool needed?

Currently replacing the pads and rotor on V40. The front brake job went smoothly, but having problems with the rear brakes.
Can't seem to get the calipher back in place - just doesn't want to sit properly. Need ideas, opinions, help please.
