Fading Brake Pedal

MY 2005 chevy silverado 2500 developed brake problems. The power steering pump, master cylinder, and Hydro static something or other has bee replaced.Now the pedal fades with constant pressure. The shop tells me this is ok but today at at a downward sloping boat ramp with the pedal at the floor, it was very scary.
Before the parts were replaced this problem did not exist.
Hope someone has a solution.

Either they didn’t bleed all the air out the brake system, or a faulty master cylinder was installed.


I will say this.

On a hydroboost system, the driver can “push through” to the floor if you want to.

This is normal . . . to some extent.

That said, it is possible there is still air in the system.

Have the shop do the complete brake fluid flush again.

Next, have the shop perform the ABS automated bleed procedure with the scan tool.

If they don’t know what you’re talking about, go elsewhere.
