Is there any difference bleeding the Brake system that has ABS from conventional brake system. Also why would the previous owner take the O2 sensor out he had an new exhaust systen put in , when I bought the car he handed me the sensor, just wondering how much that effects the car with out it.

 

Bleeding the brakes is the same. I just got done doing it on mine. The car won't run right without the O2 sensor in. Is it the one out of the header? No idea why he wouldn't put it back in. They're a pain to take out which is probably why he got a new one.

 

which ever method you do it, it's easier if you turn the car on. it makes pumping the brake pedal easier.
