check for loose caliper bolts, brake pad may be moving around in caliper or caliper bracket. missing or broken brake hardware.
Most common cause would be a loose brake caliper mounting bolts.
Not adjusted properly Parking brake not releasing fully Frozen caliper
Vibration when applying brakes is most likely warped rotors. Another cause could be loose caliper bolts.
This is probably due to worn brake rotors on the brakes, if there is no vibration when driving then this will be the cause.
Its unlikely. the more likely cause is a brake hose collapsed/split internally, after the brakes are applied the internal split is pushed back by the returning brake fluid causing a blockage in the line preventing the caliper piston from backing off the rotor.
If the front brake caliper is sticking, the disc may be uneven. Brakes that are left to scrape on the disc for a long time before they are changed will damage the disc enough to cause sticking or slipping.
If the caliper or brake piston were damaged, that would cause them to stick. Another possibility is that there is too much brake fluid and the relaxed position has the pads has them biting the disc.
Brakes 'grab' because when pressure is applied to the pedal, a device pumps fluid into a system that has a caliper (a squeezing device) that causes brake pads to squeeze the rotor (round, silver disc behind the wheel). It is quite simple.ANSWERObviously the opposite side brake is not working, or is out of adjustment. If disc brakes the side that is grabbing may have a binding caliper piston that has the lining on that side partly applied and dragging. Grease soaked brake lining from a leaking wheel seal will cause brake grab also. If drum brakes be sure both sides are adjusted equally, operate freely and have not grease or brake fluid leaks. On drum brakes the side that grabs is always the side the brake adjustment is set to tight on. Drum or disc brake, the side that grabs is the side with the defect. RE: soaked lining, adjusted to tight, caliper or wheel cylinder stuck or frozen, broken and or missing hardware. cracked drum, scored rotor etc.

a metal clip that holds brake pads securely in the caliper so they do not vibrate and cause brakes to squeak
Not usually. It is possible for the mater cylinder get suck in the apply position, but the brake pedal would not return to the up position after stopping. A more common problem for the brakes to be stuck applied is a locked wheel cylinder or brake caliper, or a jambed parking brake. These issues will be at one or more of the wheels, so check there if your brake pedal is at normal height.
