A caliper is that part of a vehicle’s braking system whose functions are vital for any stopping and slowing down of the vehicle. What then would happen should the caliper fail to function normally from whatever causes?
The most important thing to take note of is the fact that you can drive for as long as you want with a seized or stuck caliper, provided you believe that you can stop the vehicle safely. This is because a stuck caliper will not completely disengage the brakes from the surface of the brake rotor.
This obviously implies that you will only be driving with the brakes partially applied or engaged most of the time, which also means that the vehicle may not move as fast as it should. Driving under this condition also causes stress on the vehicle’s transmission system, which may in turn cause it to fail prematurely too.

Can you disconnect the brake caliper and still drive?
Yes, you can, but it is certainly not recommended for you to attempt that. If you are able to close or seal that particular brake line so that it will not result in any damage to the rotors, you can safely do it. If on the other hand, you cannot plug the brake, you are better off not trying it at all.
Though there is even an advantage to disconnecting a stuck caliper, at least if for nothing else, a disconnected caliper will not be able to partially restrict your vehicle, which may translate into reduced speed as well any increase in fuel consumption.
What causes brake calipers not to release?
The master cylinder may cause your caliper not to release when it has one complaint or the other. Whenever the caliper fails to release, it is capable of staying applied which can trigger several things in the brake system.
Some of those things that cause master cylinder issues are a warped or deformed caliper mounting bracket and severely deformed rotors and brake pads.

How to bypass a stuck caliper?
Though it is seriously suggested that you should avoid doing this as much as possible, it is still totally unavoidable sometimes.
Well, if you must bypass the caliper and safely, you can start by putting a block of wood inside the caliper and strapping it somewhere out of the way to avoid any interference. (Read Also: Will brake light drain battery? Find Out)
This should only be done on a very temporary basis until you get your caliper fixed. There is also a way of bypassing it by using a banjo fitting off the caliper and putting a regular bolt and nut through the banjo fitting.
You can also use washers instead if you want. Alternatively, you can equally bypass it by using a brake pad spreader to keep the caliper in place, before zip-tying it to the spring or shock to hold it in position.
Is it safe to drive with a frozen caliper?
It is safe so long as you believe that you can stop the car safely, and if you don’t believe that you can, please do not drive otherwise.
Similarly, in the event that you don’t know what may be the cause of the problem, do not try to drive the car, and if you must, then go about it very slowly indeed.
A frozen caliper reduces your braking ability by about half in certain areas. In addition, it causes the generation of much heat build-up in the wheels, leading to possible damage to it
How do you fix a seized brake caliper?
Commonly, a simple C-clamp is about the only tool you require to get this done effectively. Alternatively, you can remove the caliper piston with the aid of the vehicle’s hydraulic pressure.
To start with, simply remove the caliper from its disc and then pump the brake pedal in order to move the piston beyond the corroded area.
After this step, it becomes very easy to either disassemble the caliper or rebuild it entirely, the choice is now yours to make.(Read Also: Can Brake Drums Be Relined?)
How do you free a stuck caliper?
In order to unstick a brake caliper, you may need to remove the hydraulic pressure of the brake system itself.
After removing the caliper from the disc, proceed to pump the brake pedal in order to move its piston past any corrosion point. At this stage, you have the option of either disassembling or rebuilding it as you wish.

Frequently asked questions (FAQ)
Can a stuck caliper fix itself?
The most succinct answer to this question is: no, it rarely does so. However, there is still little chance of it happening, though very rarely, especially after the problem has been there for a while.
A brake caliper may begin to fail continually rather than suddenly, and it may stay stuck for some time, only for it to free itself up a few more times before it becomes stuck again. Once this drama starts, it becomes a recurrent headache really, and so the most preferable option is to give it a permanent fix once and for all.

What happens if you don’t replace a caliper?
If you fail to replace a caliper, several things are bound to happen. First, your vehicle brakes will be ineffective, particularly on the affected axle. In addition, the vehicle may not move as fast as it should due to the partially activated brake which drags it backward.
This dragging effect causes a rise in the temperature of the tire and is reputed to have caused fire incidents in some instances. Finally, as the vehicle is being dragged backward, it works against more resistance, which ultimately means an increase in gas fuel consumption by the vehicle.
Can a stuck caliper catch fire?
Yes, it can, and it usually does. Whenever the caliper is stuck, it causes dragging of the vehicle which will eventually increase the generation of heat in the brakes. If the caliper is not binding or seized, there is the possibility of a fire incident occurring. Be that as it may, there is a little consolation here since you will always receive signs and symbols of the problem long before it occurs. You only need to be able to understand and interpret them.
Can I drive my car with only three brakes?
Yes, you can, but you really need to think twice about the entire venture first. To start with, doing so may result in very serious brake fluid leakage, which may quickly leave you stranded without any brakes in the vehicle. Secondly, if you are able to plug the line somehow, your braking characteristics may still be messed up so much so that it would be totally unsafe to drive the vehicle entirely.
What would cause both the front and rear calipers to lock up?
Usually, the calipers lock up and bind together which causes overheating of the brake pads and rotors due to several reasons such as when the hardware is worn out, missing, rusted or broken. Other reasons why the brake calipers lock up include faulty brake pads, bad calipers on the disc brakes, faulty cylinders on the drum brakes, caliper piston issues, master cylinder complaints, and a host of other causes. Really, there are many varied reasons why your brake calipers may lock up, even when you are driving normally.
How can I tell if my caliper is seized and needs fixing?
Firstly, if your vehicle caliper is seized, it may be due to the vehicle being abandoned without use for a long time. When this happens, you are likely to feel as though the brakes are applied or the car may refuse to move at all.
Secondly, this seizure may be caused by bad caliper pins. At first, everything may seem normal, but then the pads will be pushed onto the disc from the side of the piston continuously. When this happens, the efficiency of the brakes is compromised and your brake pads may also wear unevenly. Curiously, your car may pull to the opposite side when you press the brakes.
Thirdly, your calipers may seize when the piston is stuck within the caliper or the pad itself becomes stuck. In this case, you are likely to feel your car down on power, just like when the parking brake is applied. In addition, you may also feel the vehicle pulling to one side of the road permanently and at any speed.
Fourthly, it can be caused by the handbrake cable or mechanism hanging up. Usually, this happens due to a lack of enough lubrication, which makes the wire or cable not travel as it should whenever you release the brakes, even though it is likely to stay on despite everything.
Fifthly, it can also be caused when your brakes on one wheel bind. Gradually, you may not observe any difference under this situation, until the authorities regrettably notify you of them during a routine inspection.
What is the remedy to a brake caliper that is seized?
Any remedy you may have will depend on the issues you are faced with, and as such there are usually only two approaches. These are:
(1). If you suspect deformed or skewed brake pads sticking to the rotors or a parking brake mechanism failure, then the case is not so hopeless. This is because all you may need to do is to observe strict maintenance and cleaning, in addition to adequate lubrication at all times.
(2). If the problem results from a seized caliper piston or slide pin, it means you will need a special tool with which to retract the pad.
Why does my caliper keep skipping?
The major reason why your caliper may continue to skip is the caliper piston itself or the brake hose. The caliper piston usually has a rubber boot on it that lubricates and also protects it. If this rubber gets torn for whatever reason, it may likely cause debris and also rust to form inside the caliper, which inadvertently means that the piston’s sliding abilities may diminish.
Can you spray WD 40 on brake calipers?
To set the record straight, you should not under any circumstances spray WD 40 on your brake calipers. For one thing, WD 40 is not only a water displacement agent but also a lubricant. Therefore, if you should spray it on your brakes, it means you don’t have any brakes left because you have already damaged them. However, if you do not spray it on either the brake pads or rotors, you can be provided you clean up the mess.
How long does it take to replace one caliper?
It can take up to about thirty minutes to swap a brake caliper if you don’t take breaks while going about it, which will prolong the process. All in all, you need about thirty minutes or less, which is appropriate as long as things work out just fine.
How Far Can You Drive With A Stuck Caliper – Conclusion
Though you can drive with a stuck caliper, it is still not very recommended for you to do so without very strong and cogent reasons. Yes, driving with a stuck caliper has both advantages and disadvantages, but the losses far outweigh the gains if any.
