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 brakes need servicing.
Brakes work by applying pressure on the brake drum and gradually slowing down your car. This should be a smooth, gradual process. If your brakes are grabbing, the process is anything but smooth - you'll feel an abruptness in the way your car stops, a sort of jerkiness.
Is your car equipped with an ABS system? That keeps the vehicle from locking the brakes to prevent skidding. The brakes automatically "GRAB" on and off to slow without skidding
Sticking caliber. Flush the brake system and install fresh brake fluid, then bleed the brakes. If that does not help, replace both calibers and brake pads on the axle where the brakes are grabbing.
the rear brakes are grabbing. the linings may have fluid on them from wheel cylinder leak or dust buildup. sanding the shoes may help .
without a little more information, it's hard to be specific, but it kind of sounds like the brakes are grabbing at the front of the car before they grab in the rear. Or, they're grabbing harder in the front than in the rear. This could be because the rear brakes are shot, because the brakes are mal-adjusted or because the brake system proportioning valve is faulty. In any case, I'd take the car to a brake professional to have it checked.
replace the brakes.grinding is caused by worn out, metal to metal pads grabbing is caused by the metal being hot and sticking
Yes, just bought a 2007 3010 trans 4x4, and the brakes started grabbing. Took it to the shop and shoes were in good shape. The grabbing stopped after I bleed off at all four wheels. I don't have much play in the brake peddle. It has done this twice and I have to bleed the brakes to free them. Nothing appears to be worn, but sure would like to know what is causing them to grab.
Rotor out of round or pads are grabbing for some reason most likely, possible bad wheel bearing as well. .
from my own experince on a 3 series....the flex lines should be changed with new calipers at around 150,000km. grabbing front brakes is a sign that one side isnt working, i replaced my calipers as one was seized up and had to replace 2 flex lines as they had collassped inside of itself over time. after 2 flex lines and bleeding all the air out of the front brakes my problem was solved. this is from my own personall experince and may or may not be the problem you are chasing but something to concider.
sound like you have "grabbing" brakes to me. i would check them for contamination and if they are then you will need new brakes and to replace all rubber components, and if your brakes are not contaminted i would start checking wheel bearings, warped rotor or drum, and the balance of your tires. i would check your rotor or drum first, that is most likely the cause
