Sounds like a brake line or other componant is leaking .. which would cause a low fluid level... which would turn the ABS light on .

Have your brakes serviced.... it could be as little as a worn out set of pads or shoes....

It is likely you have air in the system. Is the parking brake light on also? Check the reservoir. If empty or low, a leak is likely.

Please see my tip at http://www.fixya.com/cars/r6004281-brake_indicator_light_stays . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

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

ABS engages without braking


Check all wheel sensors for broken wires, loose connectors or position of sensors in their mounting brackets.

2009 Dodge Caliber - The ABS & Brake Light came on as well as the feeling/sensation of the brake being applied very hard for a split second.


take it to an accredited brake specialist shop
I suspect that the brake booster is becoming defective and the small application to the pedal causes excessive booster reaction
the abs section only maintains applied brake fluid pressure as set by the position of the pedal
that is to maintain the pressure as the stopping and start movement of a skidding wheel opens and closes a valve to that wheel /s
if you are on ice that sudden hard braking will cause the wheels to lock and immediately the abs cuts in to allow the wheels to turn and then to allow brake action to be reapplied
if the abs is working under brakes you will get a pulsating feeling under your foot as the fluid pressure is alternation between full on and released by the abs valves

Abs and traction control dash lites come on and off at various time..sometimes never come on


Your abs and traction control lights should only come on when you start to slide while breaking(ABS), and when your wheels spin in place when excelerating(TC). If those 2 things don't happen, which with some people they never do, you should never see the lights come on. Only when those mechanisms are in use do the lights come on. And they will always flicker as that is what abs and tc are, intermitant surges to break up the constant. ABS does this for obvious reasons...anti lock break, so when you slide, the abs "taps" the breaks in short bursts so they don't lock up. TC "taps" the exclelrator when it slips. Those "taps" are what trigger the lights on your dash, which is why they flicker and don't stay on.

I have a dodge caravan that has the ABS and the BRAKE light on the pedal is rally hard but it goes away once in a while for like a day and all over again


Dodge used an ABS system for 2 years that didn't have a vacuum booster. Instead it used ABS pressure from the pump motor for the power brakes. This is the system you have. The ABS pump is mounted on top of the transmission. Is the pump running when the pedal is hard to push? Sometimes the pressure sensor in the ABS module will go bad and the pump won't run. You will get a hard pedal and the ABS light and the BRAKE lights will be on. The code in the ABS control module will be LOW BRAKE ACCUMULATOR PRESSURE.

I have encended in the control panel the ligth (ABS Antiblock Brakes). Infortunatelly in Venezuela the mechanics dont have more experience with the functioning of the ABS Computer Module and Wheel Speed...


most abs faults start at the sensors in the wheels
can be dirt or other material between the sensor and the rotor, broken wiring, missing wiring, faulty wheel bearings allowing the rotor to touch the sensor tip
there is no real necessity for abs system as the antiskid action is only there to allow steering control under heavy braking
for easy stopping and moderate braking , it doesn't work.
it is an electronic controlled pump that maintains line pressure to foot brake pressure for when a wheel stops turning , the valve releases the ;line pressure for a split second and then reapplies the line pressure when wheel rotation is again recorded
get yourself a workshop manual for the vehicle ( any gm product ( suburban , s10, blazer ) will have the same system installed and the principle of operation is the same for all manufacturer models

Abs active light on, brakes pulsate when tapped. what's that mean?


The ABS Active monitor comes on when one or more of the wheels are not spinning at the same rate of speed. The ABS system determines wheel "lock up" from the wheel speed sensors and will adjust brake pressure to unlock the skidding wheel(s). It achieves this operation with a pump which will rapidly pump the brakes to the specified wheel. I'm assuming this is the "pulsation" you are experiencing. If you are having this problem under light to moderate braking, be sure to have the proper size tires on all 4 wheels. Incorrect tire sizes and uneven tire wear will give improper wheel speed information the the ABS controller. This will result in a malfunction of the system.

Chevrolet blazer 2000 abs and break light keep poing on and have a code p0452 fuel presure sensor


Hello , the abs code is prob just a maintainence light, prob is fine but GM likes to get you into the shop to have it periodicly checked out. If the abs brakes work and pulsate properly then its fine. The brake light may be a low fluid level in the master cyl reservoir . Clean the cap well and add fluid , the proper type and rating in needed. Fuel pressure sensoe may be due to a weaking fuel pump , weaking pressure regulator or dirty fuel filter. Thank you , Quinn
