Because the problem is not with pads and/or calipers. If the lights come on only when you brake, you may have a light bulb out. If they come on when you start the car and they stay on, you have a problem with your ABS system (anti-lock braking system). The systems self-check when you start the car, so the light should come on and then go out. If it comes on and stays on, the ABS system has failed. You need to have the vehicle serviced to repair the ABS system.
YEP BAD WHEEL BEARING WILL MAKE A ROARING LIKE NOISE WHILE IN MOTION.BAD WHEEL COULD PUT DRAG ON WHEEL WHICH CAUSE ABS LIGHT TO COME ON.YOUR WHEEL BEARING HAS THE WHEEL SPEED SENSOR BUILT INTO IT.SO IF WHEEL BEARING BAD THE WHEEL SPEED SENSOR PART OF ABS BRAKE SYSTEM WILL CAUSE ABS LIGHT TO COME ON IF WHEEL BEARING BAD.MAKE SURE FRONT BRAKE PADS INSTALLED CORRECTLY IF NOT. YOU WILL GET TERRIBLE WHEEL NOISE ALSO.
Master cylinder and/or brake booster could be the problem. A tiny bit of air in the system will effect your braking abilty. A fault in the ABS system would prompt the computer to trigger the ABS light. If you have brake shoes on the rear, make sure they are properly adjusted. Hope this helps.
I'd first make sure the new pads are the correct size. Doesn't happen very often but maybe the parts person gave you the wrong size pads ( for the smoking problem). As for the ABS light, most newer cars will throw out codes if you wait too long to change them out, I would contact a chevy dealer or search online about reseting the code (light).
Yes the rear has sensors, but seeing you just had front pads installed, I'd look for a loose or broken wire in the front first. I've installed front pads with the sensors and thought I got them installed right, come to find out they were not making good connection on the pads.
ABS LIGHT ON COULD BE A BAD WHEEL SENSOR CAUSING ABS UNIT LOCK UP THAT WHEEL OVERHEATING OR YOU COULD HAVE FAULT IN THE ABS UNIT.TAKE VECHICLE TO GARAGE OR DEALERSHIP.LET THEM SCAN THE ABS BRAKE SYSTEM TO SEE WHATS CAUSING ABS LIGHT TO COME ON.
Try having the dealer flush and bleed your system. It is very hard to bleed ABS systems yourself and have safe brakes that still work afterward. Bleeding non-ABS brakes yourself is easy not the same for ABS brakes. Valving, sensors and what-not require a tech and the correct equipment in my opinion. You do it wrong and you could ruin your ABS system. Do that and see if they firm up. I replaced my brake shoes/pads at the same time all new everything in back, drums/springs everything and new rotors up front. then I had the chevy dealer flush, refill and bleed system. Stiffer pedal and brakes work better. Keep in mind the brakes on 99 Tahoes are inaedequate, require new rotors often, heat up and fade/glaze pads regularly. I replace my pads long before they wear down because they glaze up and start fading early. I'll rough em up once maybe, next time, new ones. Every two brake jobs, new rotors for me. Just how it is. They will stiffen a bit and work better but they will never be awesome brakes. Just how it is on 99 and earlier Tahoes. Hope it helps. Very important to bleed correctly though. I'll bleed my 83 Toyota 4x4 myself but not the Tahoe.
u will need to check the wheel speed sensors behind the brake rotors to see if they got damaged or disconnected during the brake job, as long as the ABS light is on the Anti-lock brake system is disabled, regular braking without the need of ABS will feel fine.
first make sure to ask if the cv joints or axels are new or rebuilt,
if they are rebuilt, make sure to have the ring close to the sensor inspect for posible crack on it, and on the brake light most of timesx they come with a wear sensor, make sure that sensor is been replaced, since here you are not explaning if you replace the brakes your self or a shop did it, you might explained but i did not see it or pay atention , any way make sure to doble check than the wear sensor for brakes is been replaced, since not all the auto repairs will do it, and finally i suspect than one of your calipers might be loose, just have your car take to a diferent auto repair than offer free brake inspection and have them check for posible loose calipers
