On our truck ( 1990 Ford Ranger, my dad won it from Menards ) we are having a problem. Gas is being sucked into the brake booster. I took it into my Auto Class in school and when we were done with it the brakes gave out. My dad drove it home and we replaced it. Then we looked at it again and can smell gas in it. The truck also doesn't start very good. We changed one of the spark plugs on it too. Our next diagnosis is to look at the fuel injectors. My auto teacher isn't even sure why this is happening. Please help so I can drive it again.

Gas can't get into the brake booster due to the motor pulls a vacuum in the booster, a check valve would also stop it from happening, I would be sure the master cylinder isn't leaking into the booster. If it had gas up in it it would run so bad that most likley it wouldnt even run. Why would you change 1 plug? Change them in a set. Depends on the motor, maybe the timing belt is stretched and needs replacing. If your auto instructor isn't too versed in this take it else where for diag.

The brake booster helps boost the needed pressure to apply the brakes. It does nothing after that. The sucking sound is usually a good indicator that you have air in the brake lines and the lines need to be bled. Either at some point you ran low on brake fluid or you have leak somewhere like the bleeder valves are leaking. Edit: Whoever gave me a thumbs down, obviously you didn't read the question and you know nothing about braking systems. The question states if the booster has anything to do with the brake pads not retracting and getting the rotors and pads very hot. The brake booster has nothing to do with retracting the brake pads.

gas in the brake booster? i dont see how it is possible if your fuel injected, if it was carburated i would say you have a vacuum issue or your float bouls stuck and the fuel backed up into the carb. but regardless i dont see how you can suck the fuel up into the booster with fuel injection. but if its possible it almost has to be a vacuum issue.

You are on the right track with fuel injectors because if one of them is leaking fuel even when closed, it will cause the symptoms you describe.

Have you tried testing for any trouble codes from the computer? It's easy to do on these models. Use a code tester or google for another way to do it with a voltmeter.

That is why I drive Chevy's. The brake booster and gas line can't be combined.
