      They come out no matter how bad they are. Cut the tubing off of the nut and use a 6 point socket. the block will be fine.

      I would first check the wheel speed sensor wiring where it comes out of the wheel assembly. Usually not well protected and can get broken. Check the wires coming out of the back of the front wheels for breaks.

    The brakes are almost non-existent. Replaced brake lines and pads and bled them, but still no breaks, No leaks.,
    Had a break line bust, so replaced it. Replaced the pads and bled the breaks. Not seeing a leak in sight including on the master cylinder. Meanwhile the ABS has not worked since owning the car. I have no idea what to do at this point.

    ABS light comes on while driving and you hear a buzzing noise like electrical when you press on the brake.
    Was wondering what this could if it doesnt come on or happen ever time you press the brake?

      Please explain which brake lines you are referring, your question has no accompanying details. there are rubber hoses that go to each wheel and there are many steel lines. why do you ask?

    Antilock light
    My antilock light keeps coming on even after we have changed the brakes. Why is it doing this?

      After the brakes were changed, the ABS sensor wiring harness might not be secured back to their location, a banging could damage the harness and trigger the light.
      1. Check the sensor wiring harness and see if there is any of them had been loosed or damaged..
      2. Have a repair shop to scan and extract the fault codes.

      This is a very common auto repair. the steel brake line that runs to the rear wheels has rusted through and needs to be replaced. A new line has to be fabricated and fit to the car with double flare fitting connections. Typical cost runs anywhere from $150 to $400 depending on how extensive the replacement of the line is. Short piece is quicker and easier. Long piece is time consuming and more money. I do this repair all the time. Once a month I would say.

      Thanks. Is this something that a layperson with 75 yrs of experience caring for his own & friends' cars could do? When you say "fabricate", do these pieces come in lengths specific to each vehicle model? Or is this basically a plumbing job where you buy a replacement pipe, cut it to size, and use compression fittings to put in place? If so, exactly what kind of pipe would we ask for? Would this be purchased at an auto parts, junk yard or home improvement store?

      You take a look and decide whether the steel line is 3/16" or 1/4" - usually 3/16". You decide where to cut the line. Try to find a location where the line appears to still look like new where there is no heavy rust. The line should be cut before and after the rusted section and the line you install cannot be attached with compression fittings as they will not pass inspection and they cannot handle the high pressures. The lines have to be double flared with a double flare tool and connected with flare unions and flare nuts. You can do it but it will suck. Trust me, you would rather replace and alternator or a water pump. Buy the line in a 25' roll or in straight piece lengths which can vary from 12 inches up to 72 inches. The straight piece lengths already have both ends flared and have flare nuts in place already. Often you can just cut one end off one of these pieces and then cut it to length and then reflare just the one end at the length you need. then of course you have to bend it carefully (this line will kink if you are not ever so careful) using a bending tool if available from the auto parts store, inexpensive. But, between the bending tool, the double flare kit and your materials and fittings you will likely spend at least $50 or more. Preformed custom made lines are not available for your car beyond like 2 years after the car is in production, so, a '94 model you cannot buy these parts direct. You have to "fabricate" it to fit. The flaring of the lines takes some practice and you will have errors. My greatest advice would be this one detail. Do not forget to slide the flare nut fitting on to the line BEFORE you begin the flaring operation or you will kick yourself after finishing your perfectly shaped double flare that took you 15 minutes or more to do and then you notice that you forgot to slide the fitting in place first. Still happens to me after yeasrs of this stuff. You may also find a YouTube video on double flaring if you look.

    How to replace steel brake lines?
    One of my steel brake lines is rusted through and leaking and I have no brakes. Where can I get a diagram of where they run? Is there some new products out there that will not require bending?

      you can go to your friendly auto parts store...and they will have the oem parts on hand...with no bending or modifying required...unless you want to go at it on your own and bend things....it depends where it's at and going around....etc..suspension components....something that requires a little thought..about what might happen when this flexes or gets hot...see what iam saying?
