What causes brake calipers to not release?
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.

Unsticking a Seized Brake Caliper
Once stuck pads have been freed from a disc, the solution is resurfacing the disc and replacing the pads. Remove the caliper from the disc, and pump the brake pedal to move the piston past the corroded portion. Now you should be able to disassemble and rebuild it.
How do you free up a stuck caliper?
Once the hose beings to crack or break, it will cause brake fluid to flow onto the pistons and slow down the vehicle. The worst part is the fluid won't be able to make it back to the master cylinder, which will make the caliper stick.
You may find that the rubber boot surrounding the caliper piston is torn, exposing it to rust and debris, which can cause the caliper to stick. The solution here is to replace the brake caliper assembly. Alternatively, if a brake hose has worn out, it can also cause the caliper to stick.
Seized caliper pistons can be removed with the hydraulic pressure off the brake system itself. After removing the caliper from the disc, pump the brake pedal to move the piston past the corroded section. You will then be able to disassemble and rebuild it.
WD40 should not be put on your brakes since it can reduce friction where it is needed and even break down and damage brake components. While spraying WD40 may temporarily reduce a brake squeal or squeak, it could also cause the brakes not to function correctly when you need them most.
If the caliper is binding or seized there is a potential for a fire to occur, but there will be signs of this problem before a catastrophe happens. But if it gets hot enough the rubber seals can catch and the leaking brake fluid can also catch fire.
If you have a stuck caliper, the brake pad will not completely disengage from the surface of the brake rotor. This means you will be driving with the brakes applied slightly all of the time. Driving with a stuck caliper can create stress on the transmission, causing it to fail earlier.
The Best in Auto Repair
Labor costs are estimated between $132 and $166 while parts are priced between $442 and $736. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed. This range is an average across all vehicles on the road.
In most cases, a seized brake caliper manifests itself as reduced braking power. Usually, when a brake caliper seizes, the brake pad on the side of the caliper piston will wear excessively. Eventually, the brake pad will wear down so much that it can affect the brake disc which will get damaged.
If the brake caliper fails, the brake pads wear out faster than normal.
There is a long list of reasons that one or all of the brakes on your vehicle might lock up. These can include an overheated braking system, using the wrong brake fluid, damaged or broken parts (calipers, brake pads, pistons, rotors, or others), a defective ABS component, broken parking brake, and more.
it can be a high-pitched screech, a thud or a metal-on-metal grinding noise. these sounds can mean that your caliper is stuck, that it has come loose or that it's having some other problem.
Test the heat coming off the wheels after the test drive by placing your hand near the wheel without touching it. Sticking calipers will cause brake pads to constantly drag on the rotors of the braking system and this will create a tremendous amount of heat. The heat will then transfer to the wheel/rim of the tire.
You can, but you probably shouldn't. In some cases, you can replace just one brake caliper, but if possible, it is always best to replace brake calipers in pairs. Brake calipers are crucial to the functioning of your car. If something goes wrong with your calipers, it is a safety hazard.
Your brake calipers realistically last anywhere between 75,000 to 100,000 miles or 10 years.
