Why are the brakes soft on my Chevy Silverado?

How does the Brake bleeding sequence really matter?

If you start with the wheel closest to the master cylinder and bleed it until there is no air, and then move on to the wheel furthest from the master cylinder (just as an example), as you’re pumping the air out of that longest branch you could realistically get more air bubbles in the shortest branch.

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.

The bleed screw is located in brake caliper behind the wheel. It, therefore, resides in a challenging environment. It is disposed to heat from the braking process as well as dust and mud from the wheels. This harsh environment might cause the bleed screws to rust or corrode, making it difficult to remove them.

What causes no brake fluid to come out when bleeding?

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. It also causes the brake fluid to leak.
