Experienced mechanics share their insights in answering this question :
This problem is most likely the flexible brake hose that attaches to the brake caliper. Sometimes they will pass fluid one way and block it from releasing. You can verify this by jacking up and supporting the vehicle on the problem wheel side, pushing on the brakes, and seeing if the brakes lock the wheel from turning when you let off the brakes. If it does, then open the bleeder on the caliper and see if it releases the wheel. If it does, then you will want to replace the brake hose. If you want to have this checked before making a repair, a technician from YourMechanic can come to your car’s location to inspect your braking system and let you know what needs to be repaired.

Here are the most common causes. Caliper Slides – the slides located in the caliper can freeze due to lack of lubrication, corrosion or debris build-up. When the caliper cannot slide properly in or out, this causes the brake caliper assembly to stick.
The most common causes of your brakes not releasing is a seized caliper or brake pad. This typically occurs due to rusting or ageing. Typically, you will notice your vehicle pulling to one side when you press down on your brakes.
Your callipers might stick rather than come off smoothly because fluid can`t move back down the hose to release its pressure. If your callipers stick, then you`ll notice that something is wrong as you drive. For example, your car might veer to one side. You may hear squealing noises when you brake.
3. Piston Seizure. When driving a barely used or poorly maintained car, you`re probably driving around with a bad piston. An unmaintained caliper piston becomes heat sensitive and prone to seizing, causing brakes to lockup.
It is a “motor-on-caliper” system that integrates Actuator in the caliper mounted on the rear wheel and operates the Caliper directly without a separate parking cable.
If the temperature dips below 32°F, it can freeze, causing your brakes to make grinding and squealing noises the next time you start up your car. As your brakes heat up, the ice should melt off the brake pads and rotors, resolving the issue.

Brake Booster Push Rod Length
Similar to the above scenario, the pin between the brake booster and the master cylinder can be too long. This will not allow the master cylinder to release completely. To correct this problem, it is necessary to determine the distance between the push rod and the piston.
Due to their durability, though, it`s common for brake calipers to be replaced every 100,000 miles or ten years. Routinely having your vehicle inspected ensures every part in your braking system stays in proper working order for as long as possible.
The brake hose permits brake fluid to flow from the master cylinder to the braking system. However, if the brake hose has a slight tear, the brake fluid will flow to the brake pistons but not back. The calipers will become stuck as a result of this. So the answer to your question, YES.
A “sticking caliper” is a brake caliper that is stuck in the applied position, failing to release, even in absence of brake pedal application. This causes continual friction between a vehicle`s brake pads and rotors, which in turn, causes a certain degree of constant brake drag.
In short, no – you cannot continue to drive with a damaged brake caliper. Doing so can be extremely dangerous for both your vehicle and the safety of yourself and other road users. If you choose to continue driving your car, you could cause your brake pads to suffer additional damage.

I just replaced my brake master cylinder and the brakes still feel soft. What do I need to do after I replace the master cylinder
ANSWER : From what you’ve described you will have to bleed your brakes. Also, I believe you may have a leak in one of the lines. You may want to use a wrench and tighten the lines a little more. If you’re unable to fix this yourself, consider YourMechanic, as one of our mobile technicians can come to your home to bleed your brakes, diagnose the Check Engine Light, and help you make the appropriate repairs to your car.
Low brake pedal and anti-lock brakes are not kicking in.
ANSWER : The brake pedal is working to stop the vehicle, but there may be air in the controller unit causing the ABS brakes to not function. I recommend bleeding the brake system from the farthest location from the master cylinder to the master cylinder including the ABS unit. If the brakes are still spongy after a full bleed, then the controller will need to be replaced. If you need further assistance with your brake pedal being spongy, then seek out a professional, such as one from Your Mechanic, to help you.
Soft brake pedal after replacing rear brakes and master cylinder 2003 Audi A4
ANSWER : Hello. If you have no pressure to the rear calipers at all and if the master cylinder is new then you may have forces some debris into the ABS unit when you compressed the pistons in the rear calipers. In some cases the system can be pressure bled to fix it but it may need a new ABS unit.
I have an 05 Grand am and I just replaced the booster master cylinder calipers and lines and still have no brakes why?
ANSWER : Hi there. What you are describing could possibly be caused by a leak somewhere in the master cylinder. When the master cylinder is leaking, the pressure in your braking system will dissipate rapidly. As the pressure in the system goes, so too does the pressure in the pedal. However, this could be multiple issues as diagnosing a brake pedal issue is very difficult without being there to complete a brake pedal is not solid inspection. You might want to have one of our mobile mechanics come to your location to help diagnose this issue.
EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.
Changed brake master cylinder, bled 10 times, and the pedal is soft The rear brakes are not locked but close. Truck now running rough.
ANSWER : You will have to bleed the brakes from the farthest location all the way to the master cylinder. There is still air in the lines causing the issue. Check the vibrations on the vehicle to see if the engine mounts are damaged or if the brakes are not releasing causing the engine to run harder than normal to overcome the braking force. If you need further assistance with your vehicle’s brake system, then seek out a professional, such as one from Your Mechanic, to help you.
Replaced calipers and brake shoes. Bled the brakes and loose clutch. Get clutch back and loose brake pressure. Why?
ANSWER : Hello. The symptoms you are describing are very unusual. The clutch and brake hydraulic systems on your vehicle are separate, and should function completely independently of each other. The brake master cylinder uses a completely different set of lines than the clutch master cylinder does. I would try carefully bleeding both systems once more, just to be sure that there is no air in either system.
If both are bled properly, I would then move on to making sure that none of the components of either system are leaking. Leaks at the master or slave cylinders, or at any of the calipers or wheel cylinders will cause the systems to lose pressure. If the problem persists, I would then consider the possibility of a defective master cylinder.
