Why does my brake line bleed when I press the pedal?

One reason is shortening of the hydraulic horses which lead to the loss of brake fluids and creates space for air to get into the system. Other issues such as damaged brake lines and joints can also bring about accumulation of air into the system, causing that spongy feel when you press the pedal.

What do you need to know about bleeding ABS brakes?

Here’s what you need to know about Bleeding ABS brakes. ABS systems are VERY sensitive to air bubbles. You know that air rises in the system.

It’s not uncommon to damage the bleed screw when removing, causing it to leak and allow air into the brake system. This is often where a simple brake bleed job goes t**s up. If the bleed screw (aka bleed nipple) shears off, or allows air into the system, you can’t drive your car.

What causes brake fluid to not come out?

The screws can be removed but can’t bleed because of the blockage in the bleeding passage. Flex hoses deliver brake fluid from reservoir and brake master/cylinder to the brake caliper. In case the hoses happen to have any cut, or it’s torn out, there will be no pressure in the brakes; thus, brake bleeding will fail.
