Can master cylinder cause brakes to drag?

Can a brake booster cause brakes to lock up?
But if the booster is getting stuck in its boost mode, it will continue to apply force to the brakes, even after you release the pedal. And it’s not unusual for a faulty booster to stay on after a full stop, and then release itself. Then, the next time your brakes lock up, pull over and disconnect that vacuum hose.
How do you release a locked up brake?

Can a bad wheel bearing cause brakes to lock up?
A worn wheel hub bearing, damaged ring gear or failing speed sensor sending inaccurate data to the ECM may engage the ABS for no apparent reason when stopping, locking up the brakes. Check your tire pressure. A tire with low pressure will roll at a different speed than the other tires, sending faulty data to the ECM.
What happens when your wheel bearing locks up?
Progressive damage: Once a wheel bearing begins to fail, it will affect other components. The bearings won’t allow the wheel to turn freely, which exacerbates the problem. It also puts stress and strain on the hub, the CV joint, the axle, and the transmission.
Can ABS lock up your brakes?
ABS can pump those brakes faster than even a racing driver can, and it can direct that pulsating brake pressure to the specific wheels that lock up. If you’re having trouble with your car’s ABS, look into it ASAP regardless. A malfunctioning system can have worse consequences than just lock-ups.
What does a bad bearing sound like?
Squealing & Growling The classic sounds of a bad wheel bearing are cyclic chirping, squealing and/or growling noise. You can also tell that the sound is related to wheel bearings if it changes in proportion to vehicle speed. The sound can get worse with every turn, or it can disappear momentarily.
