The problem is most likely a wheel speed sensor at one of the front wheels. retrieving a code in the abs system could pinpoint which wheel it is. i believe the wheel speed sensor is part of the bolt on front wheel bearing assy. if you plan on doing this yourself and are mechanically inclined. you will need an a/c volt meter to check sensors. let me know if i can assist further.

How do I engage my abs brakes in my 94 Chrysler concorde


The ABS function is always on by default. You cannot just turn it off and on.

It only functions during hard or panic stops to prevent the car from skidding out of control. You'll feel a pulsation in the brake pedal under those conditions as it alternately reduces, then re-applys, the brake pressure on any wheel that's beginning to skid.

It does this by monitoring the speed of each wheel, then comparing those speeds to one another. When a wheel is detected to be slower than the others, it indicates a skid is happening, or about to happen, on that wheel. The pressure is then momentarily reduced on that wheel to allow it to regain traction.

Brakes grab and anti skid light comes on during acceleration


Check your rear Emergency brake shoes inside the rear rotors. When the brake lining falls off of the metal backing, the linings get ground up inside the rear rotors. The pulverized lining coats the ABS count sensors and the vehicle thinks both rear wheels are turning at different speeds.

That is when automatic anti skid kicks in. The brakes try to stop the spin of the fastest wheel and intermittently applies the brakes.

Remember there are 2 sets of brakes on each rear wheel. The calipers are visible but the drums are concealed as part of the rotor housing.

What it the silver tube on the rear brakes? part says Delphi than numbers 2076/2 and .3/3.0 and theres 2 on the car. one for each rear line.


If you are talking about the tubes in the brake lines themselves, those are pressure reducing valves. They keep your rear wheels from skidding as the weight of the vehicle shifts forward when you stop. If the same fluid pressure was applied to all four wheels, your rear wheels would skid, even under moderate braking.

What is abs how it function


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.

I hope this helps you and please vote for me :)
