99 caravan 3.3 no abs brakes. I have replaced a bad master cylinder and all 4 rusted brake lines. The ABS brake warning light is not on. The van does not pull to one side.


Something is wrong with your statement
it is a 99 caravan 3.3 no abs , then you are on about abs light pump etc
the abs pump only works when the master cylinder is under pressure and that pressure is suddenly reduced by the sensor reading a locked wheel and a valve is opened to release line pressure to that wheel As soon as that wheel starts to turn, the valve closes
while the wheel is stopped and that valve is open , the abs pump kicks in to maintain line pressure otherwise the brake pedal would go to the floor
master cylinders work through a. abs unit and not because of it so if the master cylinder becomes faulty, the abs pump will not operate until a wheel stops turning as there is no line pressure to stop a wheel turning
the abs light may not be on because there is nothing to operate the system to put it on

What is a abs modular on a Escalade Cadillac?


Jesse, The module will not stop fluid to rear brakes, a bad master cylinder will,leaking lines, air in brake system, faulty metering block if equipped, collapsed flex lines or pinched brake line faulty caliper or brake cylinders,etc. will cause the possible feeling of no rear brakes.
(ABS Module components) the ABS speed sensors and the ABS control module . When the brake is applied, the ABS control module reads the speed data from the speed sensor and sends the correct pressure to each wheel to prevent any wheel lock up, eg. sliding/skidding Links below have more info.

Is the pump faulty?


abs units only maintain the brake line pressure as set by the brake pedal position and application pressure during wheel lock up prevention
If it activated on it's own accord both rear brakes would have come on if not all 4 wheels
the default action in the event of abs failure is to loose the abs action during wheel lock up and not to lock brakes
Run the fault codes to check for ABS circuit/ sensor problem
discuss the problem with an accredited brake specialist shop as I suspect a problem that is not really connected to the ABS system

ABS CHECK LIGHT DOESNT COME ON WHEN YOU TURN KEY ON


1. I would not be concerned because if there was a failure in the ABS you would definitely get an ABS warning light and the ABS and most likely the stability control/traction control systems (with added warning lights) will all switch off .

2. You can test if the ABS is operational. On a very quiet damp surface, straight, wide road( with NO other cars around), apply your brakes hard from a very low speed - up to 20 mph ONLY driving in a straight line - until the car stops. The front brakes should attempt to lock up under hard braking and if the ABS is operational you will feel it kick in and the brake pedal will pulsate as the ABS constantly allows brake pressure and then releases it to prevent the wheels from locking up on the damp road. If the ABS does not kick in be ready to release the brake pedal quickly to allow the wheels to rotate so you can steer the car safely. Without the ABS the front wheels should begin to lock up on the damp road surface due to the low level of tire grip. ONLY test this at very low speed and ONLY when driving in a straight line on a straight section of wide road with no other vehicles around.

Can i un-A.B.S. MY 1997 ford falcon futura wagon,


the ABS is a system that allows wheels that have stopped turning under brakes to turn again momentarily
the brakes work through the abs system normally at all times from the booster and it is only when a wheel stops turning that the electric motor in the abs unit provides pressure to a line to compensate for the fluid returned by the valve in that line that was opened when the wheel stopped
you can disconnect power to the abs ( fuse ,relay) and the brakes will still operate normally except that when in extreme braking situations the wheels will lock up and steering control will be the same as pre abs cars ( side skid and not able to steer around an object)
there may be a abs light come on but you will have to live with that
best talk with an accredited brak specialist shop as they may have an idea as to what can be done to bypass the abs
remember that the abs is part of the vehicle safety requirements and in by passing it or making it inoperable you may be making the vehicle un-roadworthy for the purposes of inspection and insurance.

Will the abs sensor lock up the wheels on a 2004 Chevy Tahoe


No, an abs sensor only senses the speed of the wheel. When one wheel locks up or is running considerably slower than the other wheels during braking the ABS system will reduce the braking power to that wheel to stop it locking up, hence the term Anti Lock Brakes. This happens in milliseconds. The sensor itself cannot lock a wheel up.

Right rear wheel will not turn 2004 xl7 susuki


This car ABS, if yes, try posting that, as i will answer for NO.
NO = short and easy. ABS = hard. (read the FSM , and see)
find a real shop with the ASE sigh,
never go there again. your dealer, he is bad for your health and others.
yes, my same bearing failed on my 04 but i found it with an electronic stethoscope (sonic ear) in 5min and did it early before brake damage.
locking brakes are very very bad , you need to find this fast.
he sounds incompetent.
if the Right rear is locked, the mech, loosens the bleed fitting
if it unlocks the MC is failing,(non ABS). mine is non ABS too.
if a new mc is installed and the rear piston clearance is not set
the MC will LOCK THE WHOLE SYSTEM up. or 1 end.
if the brake didnt release above, that means (gee simple) the brake neat
is locked. (bad bearing or wet soaked brakes or the parts assembled
ALL WRONG here.
puddle on floor, is it DOT3/4 fluid or GL4 gear lube.
surly you can tell the diffr, between them.> no?
if fuild that is wheel cylinder failure.
did you use non DOT/3/4 fluid, you must not use dot 5 or the seals will fail FAST,.....
using jiffyboobs? dont/

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 :)

ABS light stays on sounds like a abs pump is staying on. Is there a pump for the abs system?


There is no seperate pump. The following lines will give you more details

Braking force and the tendency of the wheels to lock up are affected by a combination of factors such as the friction coefficient of the road surface, and the difference between the vehicle speed and the road wheel speed. The ABS prevents the road wheels from locking up during heavy braking by controlling the vehicle's brake system hydraulic pressure.
During normal braking, as the rotational speed of the wheel falls, no electric current flows from the ECU to the hydraulic unit. The solenoid valve is not energized. The brake master cylinder hydraulic pressure is applied to the brake unit, and the ABS is not involved. However, even though the ABS is passive during normal braking, its control module is constantly monitoring for rapid deceleration of any of the wheels.
If a wheel-speed sensor signals severe wheel deceleration - which means the wheel is likely to lock up - the ECU sends a current to the hydraulic unit. This energizes the solenoid valve. The action of the valve isolates the brake circuit from the master cylinder. This stops the braking pressure at that wheel from rising, and keeps it constant.
If the sensors signal the wheel is still decelerating too rapidly, the ECU sends a larger current to the hydraulic unit. The armature moves even further and opens the valve. It opens a passage from the brake circuit. Brake fluid is sent from the brake circuit back to the master cylinder. Pressure in the brake caliper circuit is reduced so that the wheel is braked less heavily.
If the wheel sensors indicate that lowering the brake pressure is letting the wheel accelerate again, the ECU stops sending current to the hydraulic unit and de-energizes the solenoid valve. This lets the pressure increase, so that the wheel is again decelerated.
This cycle repeats itself about four to six times per second.
It is normal in an ABS for the valves in the hydraulic control unit to keep changing position as they change the brake pressure that’s being applied. These changes in position may cause rapid pulsations to be felt through the brake pedal.

The abs light came on, 2000 ls


if abs light is on it means your abs system is not working properly due to disconnection of sensor of any wheel or problem with abs module but it dosn't mean that your brake will not work it will work but it will work like non abs brake , car wheel can get lock while sudden braking, don't worry but drive carefully, thanks.
