Abs activates every time I apply the brakes. No light comes on. I can feel it .

You may be right in that the brakes are applied.
The ABS would need to be checked for trouble codes to proceed.
You could also lift one wheel at a time to see if the brakes are on.

I had the same problem with my 2002 Silverado. The grease seal on the right front wheel bearing went up letting grease build up on sensor . Disconnect ABS sensor wire at wheel one wheel at a time. Abs light on dash will come on but that's ok. drive and stop easy with wire disconnected until brakes feel normal. Then you will know wheel is the problem.

If the abs warning light is on, you will need someone to scan the computer for trouble codes to proceed.

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

There's a service bulliten about that problem with rust build-up on the front hubs pushing the sensors out of posistion [ most common on the pickups in areas that use road salt ], it happens mostly at very low speed. The best way to find out the problem is to have the system scanned.

If the abs light is on it is one of a couple things that come to mind.
1. The fuse for ABS under the hood has blown
2. You have a bad ABS sensor on one/more of your wheels

Does the light stay on all the time, or does it come on when you turn into a parking spot and apply the brake(usually making a humming noise that you can feel in the brake pedal)?

have car scanned auto zone -advanced auto and some other auto stores will do this for free most likely one of your sensors is starting to go bad usually will activate at low speed under 10 mph as ur slowing down do check this problem early as abs can cause vehicle to stop longer

it could be a bad fuse, but is most likely a problem with your abs system.

it means that you are having a malfunction with the abs system on your brakes....id have that checked immediately by a certified mechanic

if abs activates when it should not,,, it means abs module senses one or more wheel sensores under 3 mph and the other sensores are above 3 mph. .the cause of this is usualy a bad wheel speed sensor or excessive air gap between the sensor and ringwheel. you need an abs data scanner to hook up and go for a test drive to find out which sensor is the culprit.
