I'll start with a picture of the rear brake problem
Now some of the lights that come on. Oath the brake and the brake elect boost come on when I press the brake pedal
Now of the parts under the hood
And the brake pedal
The main questions are. What do you guys think the wires on the brake pedal feed?
What is going on under the hood what is the grey sensor wire? And what is the pump under the brake booster, how how does it all wire up?
And why is the electric brake boost light coming on?
