There are 2 rubber seals on each end of the wheel cylinders and there leaking. REPLACE THE WHEEL CYLINDERS.
Failed caliper, wheel cylinder, hose, or line.

master cylinder is bad or air in brake system or you have a brake fluid leak somewhere in the system. look on the back side of the wheels in the rear and see if you see fluid. On the front you can easily see both the front and rear side and see if you see fluid. Sounds like a brake fluid leak somewhere as it is a closed system or did you replace the shoes or pads and didn't bleed the air out of the system.
That sounds like a wheel cylinder leaking brake fluid.
park it on a dry patch of pavement and pump the brakes like crazy If you are loosing brake fluid and can't find an external leak--remove master cylinder and look at rear and also in booster for signs of fluid--indicating a bad rear seal in master cylinder--excess brake fluid will be sucked through vacuum lines
You can cutoff the rear brake line. You will no longer have rear brakes and the fluid will leak out. It is not recommended that can't off the rear brake line, without replacing it.
Hello In the 2004 Corvettes the Transmission has been moved from the back of the engine to the rear so now the transmission and pumpkin are bolted together. You could have a transmission leak or a brake fluid leak. If the leak is in the center then I would go with a trany leak if leak is near either tire go with a brake fluid leak. Hope this helps
No. Get it fixed as soon as possible. When you have brake fluid leaking out of your rear cylinder, you are putting lubricant on your rear brake. That is keeping that brake from working. It is also letting brake fluid drain out of the car. Your car needs brake fluid to stop the car. If you lose a lot of brake fluid, you will put your foot on the brake pedal and it will go all the way to the floor and nothing will happen. It can be dangerous when you drive down the highway at a high rate of speed and put your foot on the brake pedal and nothing happens. When you crash your car and turn it into a piece of scrap metal, you could get hurt.
It could be at the wheel brake cylinder or a junction at the rear axle.
Normal leak points that are hard to see are inside the rear drums, along the frame, and into the brake booster.Normal leak points that are hard to see are inside the rear drums, along the frame, and into the brake booster.
You might be out of brake fluid. Our rear wheel cylinder was leaking and ran ours out of fluid and the light came on.
It would be helpful to know: What vehicle you are working on. The condition of the rear brakes, and were they also bled. Does the brake fluid level stay full, if no then there may be a brake fluid leak.
