This will depend on the car.
This is about a basic brake system, No ABS:
No. If your calipers are leaking, they need to be replaced. Calipers leak because they're worn out, or because you didn't change the fluid and it corroded the inside of the piston bore.
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.
leaky wheel cylinders or calipers
MOISTURE IN YOUR BRAKE FLUID. FLUSH SYSTEM WITH NEW FLUID.
Any fluid other than brake fluid will ruin the master cylinder, abs unit, brake hoses, and calipers.
check brake hoses. check brake fluid condition, if fluid is contaminated or mixed with wrong fluid, calipers can lock-up or stick. check caliper bolts, hardware, caliper brackets. replace if broken, bent, or missing.
You can purchase a disc brake tool for compressing the calipers at any auto parts dealer for about $8.00. You will also need to have the brake fluid filler cap off.

Usually it's low brake fluid or a problem with the abs. Check the brake fluid reservoir. Often the brake fluid will go down as the brake pads wear and the calipers has to travel further.
Check for sticking calipers.
The clutch fluid on the manual transmission is actually shared with the brake system. Like each brake caliper, the clutch has its own bleed screw located between the engine and the firewall. Simply follow the same process for bleeding the brakes by purging the fluid starting with the rear brake calipers, then the clutch and lastly the front brake calipers.
