PWR light issue and no brake fluid after winter storage

[Ivan141]

Econ / Pwr light functions on vacuum. Check your vacuum lines to see if a rodent might have taken a nibble from one during winter.
The switch is on the right fender near the inlet manifold IIRC.

I would not take any chances with your brake system. It must be leaking somewhere since last time I checked the pixies dont come to suck it out over winter.
Since I dont know your car yet, perhaps you could tell us what model you have exactly. If you have an SR5 with drum brakes you might have a leaky rear cylinder.
On disk brakes everything should be in plain sight. Perhaps sprinkle some talkum powder around the brakes and leave it to sit for a few days. Any leaks will leave traces in the powder.
