Where is the REAR brake pad sensor harness?

y2k_o__o · 03-17-2015, 10:05 PM

I was going to replace the rear brake pads
Took everything apart and trace the sensor wire through the trailing arm and wheel well.

Where the heck can I take the harness out?

There aren't much resources on google how to access this..

It's getting dark outside now, I have to put everything back together and back to square one

Ok, to be clear, what are you trying to do? Replace the wear sensor? Trace the wiring? There's a little compartment in the engine facing side of the wheel well where things land. Not sure if that helps.

I was replacing rotor, pads and the sensor

but it seems like there is no way to reach the harness and take it off

How did you all DIYers managed to do it?

You can definitely replace it.
It's easiest if you remove the other plastic bits first.
The termination box is up in a little cavity in front of the right rear wheel.
