Car wash, hit a puddle... if it's water.

If it's oil/feels oily, prolly the last time the car was serviced & the parking brake cable(s) were adjusted.... if there was some rust on the adjustment nut, there was some WD-40, PB Blaster or light oil squirted in the area.

Take a look at where the driveshaft & rear end connect (pinion area), and see if the u-joint & front of the rear end look wet, and if the floor pan in a horizontal plane in that area looks greasey or oil soaked. If it all mostly dry, no worries.

Additionally, if you just had the rear brakes done on the car in the last couple months, I'd bet it was oil/solvent squirted on the parking brake adjuster. Kudos to the wrench that adjusted the brake cable.... most shops skip that step.

 

Local auto parts won't be able to read the codes. His is a '94.

Brake work or fuel work was done at some point. I see a compression fitting to the left of his red box pic. Hard to tell what size line it is from the pic.

 

Yea i did the compression fitting... its a 3/8ths line

 

common issue with abs light is a failing front wheel sensor or wheel sensor harness. be worth it to test them.
