Having problems with your 1992 Ford Thunderbird ?
Is there air in my ABS of my '92 thunderbird lx?
\015 I have a 1992 Ford Thunderbird and the brake light and ABS light are on and in addition, my breaks seem like they're not responding. I have to push harder on them to get the car to slow down. Spongy? I took it to a repair shop and they told me it was the booster(which is partly attached to the master cylinder) and it would be a 2600 dollar fix. LOL I took it to o'Reillys and told them the same thing I told the repair shop. They said the same thing. I just now looked online and I'm getting more links to bleeding the ABS(which the repair manual recommends after replacing the said parts). I wanted to know why. I found out it could be because there is air in the system. How do I tell if that's the only problem, not the parts(that look fairly new under the hood)? How do I bleed the ABS to get rid of the air?\015
ABS isn't so much a thing as a system, but if you want to know how to bleed your brake system you place a tranparent tube on one of the brake cylinder valves/nipples, then imerse the end of the tube in a small bottle with some brake fluid in. Then you get someone to press the pedal down slowly as you open the valve/nipple. They should pump a few times slowly, then with the pedal down close the valve/nipple. Check to see if the pedal is harder. You should do this with both front and rear brakes, as they are seperate lines. The ABS is a system that ballances the brakes to stop slewing across the road when you apply the pedal too hard. The part attached to the master cylinder is actually a servo, which should have a tube go from it to the inlet manifold of the engine. This causes a vacuum in the servo, which when applying the brakes helps the brakes by taking away some of the pressure needed. If this pipe is broken or not connected, then your sevo won't work. There is an easy way to check your servo. Press the pedal down, then start the engine, you should feel the pedal go down a bit more. If it does not, check the servo tube.
