The tires of my second hand jeep often lock when I need to brake suddenly or stop quickly. This often occurs when I am trying to stop downhill. I have a feeling this is to do with the ABS as the ABS light on the dashboard never lights up. What's wrong with it!!

Re: ABS not working
When you put the ignition on, does the ABS light come on? If not may be the previous owner has removed the bulb because ther was a fault with it? if your answer is positive then probably the beat thing to do is to insert a new bulb and see if the light stays on. Check the fuses and remove the battery terminal for 6 minutes and refit it an start the car and see what it does. If it stays on then you'll have to get it scanned.

No not at all. ABS issues will not leave you on the side of the road stranded, will not cause your engine any problems. When the ABS light comes on, it basically deactivates your anti lock brake system, giving you the same brakes we had back in the day before technology came into cars. You will not notice a loss in stopping power and your brakes will not be affected. Before the light, if you were to slam on your breaks, your tires would lock up for a split second then release, then lock, then release, keeping you from going into an uncontrollable slide. Now if you slam on the brakes, they will lock up and stay locked up until you ease your foot off the brake pedal....don't slam on the brakes. :-) Not saying you shouldn't get it fixed because it is a good safety feature to have for those who do panic and stand on the brakes. But you don't have to make it a top priority fix if budget doesn't allow for it.
ABS has a sensor which is basically like a metal blade which sticks into the tire attachment into grooves.As the tire turns,the blade senses the RPM.When you brake suddenly,the sensor tells the computer when your tire is about to skid and releases brake pressure.It applies and releases brake pressure very quickly so as not to cause a skid.One of these may be going bad.A computer check can tell you quickly,but you probably know about computer application pricing.If you want to buy one and switch tires every couple days you could probably find out,but it would be very tedious.Good luck.
ABS is anti-lock braking system. It is a range of four sensors which monitor the braking capability when you apply the brakes. If you are harsh and stamp on the brake pedal there is a risk of the wheels locking up and sliding (screeching from the tires).
The ABS sensors modulate the brake caliper pistons andapply and let go the brakes very quickly. This stops the tires from skidding and you will feel a pulse through the brake pedal as the hydraulic system is forced to release the pedal slightly for a fraction of a second.
As ABS stops your car from skidding it allows you to turn the steering when you are braking hard. This is good news for avoiding accidents. If you lock the wheels on a non ABS car, you continue in the direction of the wheels - unless you release the brakes and reapply quickly (same method as ABS) this is called cadence braking but when involved with a potential accident the last thing on people's minds is to release the brake pedal. Having only owned older cars, cadence braking is one method I've learned, especially from driving in the snow.
dosen't stop at all or just slow?, if the abs is working then you should feel the pulseing in the brake pedal just before tire lock-up, the tires will not lock-up with abs fully funtioning unless all four tires or two are in lock-up depending on the abs application, if abs fails it reverts it self to regular braking ability, hope this helps
actually it could be something as simple as low on brake fluid. check this and then check to make sure you do not have worn brake pads on the tires this can also set a code when one tire stops quicker than the other
When the ABS light comes on that means that the sytem has a problem and whenever light is on the system is in-operable. Most of the time there is a problem with one of the wheel speed sensor. On this particular vehicle there are(4) abs/speed sensors (one in each wheel)basically the all tell the computer what speed that particular wheel is going, at anytime. This sensor is mounted on/in the wheel hub and gets its signal from a gear mounted in the hub or and axle in the hub with a gear on it. When the sensor sends a signal to the computer that the wheel is about to skid/lock-up it pumps the brakes 15 times per second to prevent it from locking up. I believe that the sensor on the right rear wheel is not working and therfore it locks up. Good Luck and contact me if you need more help. Please leave me a fixya if I fixed ya.
Sounds like a bad ABS sensor in the system. The quick fix is to locate the ABS fuse in your fuse panel, remove this fuse and abs is disabled. Your brake will function normal and it is safe to drive w/o abs until you can have it checked out, keep in mind you will lock you brakes under heavy braking conditions.
