My antilock brake warning light keeps blinking. I have replaced pads and checked fluid levels in reservoirs but it wont stop

replace the brake light sensor manual will state where it is located

If the parking brake switch is not stuck and the fluid level is OK, try tapping on the fluid reservoir to see if the light flickers or goes off. (you need 2 people to do this) If it flickers or goes off then replace your fluid level sensor. (You may have to buy a complete reservoir or master cylinder depending on your car ) If this does not provide any results, then you may have an internal leak in your master cylinder or Antolock Hydraulic Control Module causing the Proportioning Sensor Switch to turn the light on. At this point. I would tow it to a shop and have the Antilock Control Module scanned to see why it has turned the light on and disabled your Antilock Brake System. I do not recommend driving the car at all until the RED brake warning lamp problem has been resolved. It is OK to operate the vehicle (cautiously) with the YELLOW Antilock brake lamp on.

Check your brake fluid, there is a level sensor in the brake fluid reservoir, if the fluid is low it's usually a sign that you should check your brake pads/shoes for wear, if the pads and shoes are ok, then top off the brake fluid and keep an eye on it for leaks (just make sure it doesn't get low again quickly).

hi from uk the stop/handbrake light has two warning functions it will illuminate when hand brake is applied or is left on whilst driving or not fully off position ?? the other function is it is warning you that your brake fluid in the reservoir is low/requires topping up ? if it is low ? this could be due to a fluid leak ?either from pipes or wheel cyl's/calipers ? OR ? just that as your b/pads and shoes wear lower then fluid from reservoir displaces from res to cyl's to compensate for wear so may i suggest you 1st check fluid level+top up if low? then check for leaks as above more important have your brake pads and rear shoes or pads if fitted checked for wear/safety i advise this considering age/milage? of car and if you have no record of being checked/replaced recently? if your brake pads are fitted with low pads wear indicators this will also give warning hope this helps? good luck !

hi from the uk this warning light has two functions 1st it comes on when park brake is on then goes off as p/brake released the other function of this light being on ? is a warning that the brake fluid level in the reservoir is low the sensor is on the fill cap however! low level may be a fliud leak ? orsimply the level has dropped over time due to as the brake pads and rear shoes wear down then the fluid displaces from reservoir and compesates for the wear and fluid keeps the w/cylinders always topped up automatically may i suggest you check your b/pads and shoes are not too low for safety if so then renew asap also make sure there is no sign of fluid leaking on brakes especially the rear cyl's and actual b/pipes hope this helps?

hi from uk if as you say the brake fluid level is slightly above min ? then this is most probably the reason the warning light is on this light is also linked to both park brake when on and a visual warning via a sensor on the reservoir that brake fluid is low top reservoir up ? light should/will go off however! fluid level drops for two reasons = 1 fluid leak on b/system 2 or in your case the fluid level has dropped by displacement from reservoir to brake calipers/cylinders as the brake pads and/or shoes wear down to minimum safe thickness ? and if your car has brake pads wear indicators fitted to pads these sensors will put light on SO may i suggest you check your brake pads/shoes ASAP because if pads/shoes are very low ? you may not only damage the more expensive disc/rotors but pads may/will burn up resulting in brake failure with obvious results ? hope you heed this advice? it is for your safety and other drivers best wishes

The emergency brake light is also the low brake fluid warning light. Check the level in the reservoir. As the brake pads wear the fluid will drop, so if the brake fluid is low, check the pads to make sure the lining material is thick enough. If you have drums in the rear, check the wheel cylinders to make sure they aren't leaking. If everything checks out ok just add a little fluid to the reservoir and that should take care of the light.

First thing to do is check the brake fluid reservoir and make sure the level of fluid is sufficient. Low fluid level can cause what you're experiencing. If the fluid is low, add brake fluid. Keep an eye on the fluid level, since all this could be due to a leak in the brake system. If adding fluid does not help, you'll want to get it checked by a professional.

hi for info the brakes warning light on dash is also an indication that brake fluid level is low? or there may be a leak resulting in fluid level drop ? also considering age of car you may need to inspect brake pads wear ? if your car has low brake pads wear indicators attached to pads ? or the hand brake switch req's checking to ensure it is being pushed to off position when h/brak is down ? so fluid level low is the obviouse 1st check as fluid will displace from reservoir as pads wear low hence the level indicator on fill cap trips on may i suggest if it is low level b4 you top up? check your b/pads if you have not done so recently? or replaced since new ? hope this helps you locate problem best wishes from the uk

Hi,

Based on your description, if it is red that would be the "Brake System" warning light. This warning light indicates that the hand brake or the park brakes are engaged. Alternately, this could also indicate that the level of the brake fluid in the reservoir is below nominal. Top off brake fluid if low and have your brake pads checked as well as visually inspect for any possible brake fluid leak.

On the other hand if it is yellow that would be the ABS (antilock brake system) Light. Momentary lighting up would be normal at startup but consistent light would indicate a malfunction in the brake system such as either low brake-fluid level, stuck brake caliper or faulty ABS. Check brake fluid level and have your vehicle's brakes checked.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
