Extra Small Spring

Can someone tell me what this extra small spring is? Yellow letter on it
Driver side front , 2020 Trd off-road

 

Brake line.

 

Its a fluid line, I think its a brake line thats coiled up to make the front brake lines the same length.

But im not sure.

 

lol op did you follow it?

Aint no spring, its the brake line. They coil it like that so there can be flex between the body (where the master cylinder is mounted to) and the brakes that are mounted on the frame. Both sides have this as well as down on the driver side frame where the brake lines leave the firewall bottom and attach to the frame.

 

Here my dummy ass thought it was a extra bump stop or something...
lol

after the clarification, I open the hood and did follow the line. Yep, it’s a brake line. Haha

thanks again for enlightening my curiosity
