Second "Brake pad spring" installed
I'm not quite sure if everyone notice that there is ONE brake pad spring installed. In fact, there's space for the second brake pad spring. The purpose of this installation is to apply equal pressure on brake pads.
After installing this small part on, you can feel the difference instantly. With the same operation as before, you can stop the vehicle with shorter distance. In other words, the braking ability is simply improved with low cost.
Strongly recommend to try it, and you won't regret.
This is how it looks like.
Before installation. It's empty in the red circle.
After installation. The second brake pad spring is in place (red circle).

do you have a part number on that? where did you purchase?
any idea whether this helps with brake squeal issue? I had noticed early on that this spring was missing and that the service manual showed both springs installed. Wonder whether lack of spring allows pads to vibrate in reverse causing squeal and then that would explain why there is no squeal when braking going forward.
cheers.

Maybe I am missing something, but how would a second spring improve braking performance? The only purpose of retention springs is to keep the pads from rattling in the caliper / around the pins. Retention springs have no effect on clamping pressure applied by the pistons. I fail to see how having two springs would enhance performance.
