ABS light stays on but car stops normally.

id check your caliper to see if the piston is compressing all the way if not check your fluid it should be clean not brown or if you have been through large amounts of water if it has gotten into the brake system and check your bleeder valve to check if it has rotted or come lose or if you have a break in the lines or air, most likely your caliper is failing to compress.

Well u have to check brake pad sensor or brsk fluid level first

sounds like a short circuit

Hi:
The ABS light on means an ABS malfunction. You should be able to have a auto parts store scan your car and find out what code is tripped, for free, but my guess is that one of your front wheel speed sensors is out of whack, or dirty or something.
When the light is on, your normal brakes work fine, but you have no ABS, so your car will take longer to stop in emergency situations.

Sounds like one of the sensors at the tires is not working right. Its actually better if the light stays on. With it turning on and off will make it harder for you to stop cause the computer does not know what to do. Check brake fulid level. If it stays on you will have normal brakes. Have the sensors checked or replaced. ABS was design for panic stops so you don't lock up the tires an skid.

your abs unit is failing and needs replaced ...the procedure for testing is to backprobe green wire in abs connector and watch voltage wave pattern on a scope ....it will show voltage does not go from 0 to 12 but only 4 to 12 volts that verifies problem is abs controller.

Sounds like your getting abs activation when its not needed. Most likley one of the wheel speed sensors has failed. You do need to have a scan tool to read the live data from the abs module as the problem is occurring to pinpoint which sensor is faulty. The abs light will not come on because the abs module thinks its just working normally. I'm an ASE certified mechanic and have seen this problem many times on various vehicles. You might have to pay somebody to diagnose it, but replacing the sensor it a very easy task. I hope this helps.

ABS went out while racing. I got a replacement from haprecycling for about $150 vs $1000+

just fyi, it's a pain to change. You will need a set of flare wrenchs and crows feet to get it in and out properly. Be VERY careful not to strip or cross thread the gettings.

metal cap should not come off when removing sensor. Sorry it sounds like the sensor is damaged
