Corrosion?
Contaminated brake fluid?
Brake calipers are what house the brake pads and fit over the rotor. If you are working on the brakes, usually the calipers need to be taken off in order to work.
Cailbers have NO adjustment. They have a piston that moves in and out as the brake is pushed down.
All brake hoses and calipers must be intact and hooked up to bleed any brakes. You cannot do it with hoses removed.
There are no calipers used with brake drums. Brake drums work with curved brake pads pressing against the inside circular surface of the drum when the brakes are applied. These pads are held in place and pushed by a spring and lever assembly that is mounted to a steel plate attached to the wheel or axle of the car. This plate does not move. Calipers are used with disc brakes to hold the brake pads on both sides of the disc brake and to apply them against the disc when the brakes are applied.
bad calipers change them yesterday not tomorrow
yes
Sticking brake calipers. This can be caused by moisture in the brake fluid which will cause the calipers to rust. Replace the calibers and replace all the brake fluid. It can also be caused by driving with your foot on the brake.
not lubricating your slide pins when you replace your brakes
Check for sticking calipers.
The brake calipers can be the same the front calipers on turbo cars is normally bigger as up to 90% of your braking force is on the front brakes but the back ones are somtimes bigger not always
If the brakes are disc brakes then try opening the bleed screws on the calipers and see if the pressure releases if not then remove the calipers and replace because the piston is probably frozen or you can try pushing in the piston with a c-clamp,if that doesnt work replace the calipers as noted. If the brakes are drum brakes then check your brake cylinders to see if they are leaking if so you can usually rebuild them if not then replace them and bleed your brake system to get brakes back to normal, you can also make sure your drum brakes are adjusted correctly.
To thoroughly replace and repair brakes, one must replace the brake light wiring, brake pads, and brake calipers. Furthermore, one should reline the brakes.
