The brakes could be binding or a caliper could be sticking. Remove the wheels and make sure that the brake system is operating properly.
The ABS wheel sensor sends a signal that the car might be in trouble. If the car is sliding or feels like it might spin out of control, the brakes are automatically cut on.Ê
Front wheel brakes are generally effective in most conditions, providing good stopping power and control. However, in certain situations such as wet or slippery road conditions, front wheel brakes may not perform as well as other types of brakes like all-wheel or four-wheel brakes, which distribute braking power more evenly across all wheels.
Sounds like problem with brakes. Pull the wheel and you should see the problem.
One wheel of the brakes may be "grabbing" because of cracked brake linings or broken hardware. Have the brakes safety inspected soon!
Sounds like the pads are shot. Take a wheel off and check.
it could be the rotors
Sounds like your handbrake is stuck or rear brake drums are seized. Check out hand barke system and rear brakes.
You don't need a CDL to operate a vehicle with air brakes if the vehicle doesn't fall within the requirements to mandate a CDL licenced driver to operate it. For example, RVs often have air brakes, as do many of the trucks manufactured for companies like FedEx, UPS, Merita Bread, etc.
It's hard to diagnose without hearing the noise, but if you're sure that it is not the brakes, it could be dirt/sand/rock in the brakes. If you're hearing the sound all the time (even when not applying the brakes), it could be wheel bearings.
make sure it's not the rear brakes hanging up, see if they feel hot, if you have drum brakes on the back a wheel cylinder could be hanging up.
When your brakes get harder and harder the more you use them and lock up, this is a symptom of brake failure. You need to take your vehicle to a qualified mechanic.
Check your brakes, sounds like they are stuck on. If the brakes are ok the problem is in the transmission. Possibly the convertor or the front pump.
