Brake Issue

I have a 2001 Olds Bravada. Lately I have been having a problem with the brakes. There are NO leaks and it is full of fluid. The problem is that sometimes when I brake, and I mean easily, not slamming on them, there is a popping noise and the brake pedal pushes back into my foot and the vehicle doesn’t want to stop. I have to really press hard to get the brakes to work when this happens at all. It does have an ABS system but the light doesn’t come on when this happens. At other times the ABS light does come on but when it is on there is no problem.

I have had one person tell me this has to do with the vacuum hose to the gas tank being the problem. Another says this only happens with the brakes if I drive through water or hit ice, even though I have told them that no, there have been times that there has been no puddles or ice. Someone else said that it is the gears shifting, since it is all wheel drive, yet I have never known brakes to fail when gears shift. Another person said this was common in the Bravada, which sounds like bunk to me since it is obviously a safety issue.

Can someone PLEASE give me some insight into this and what might be going on? Thanks in advance.

Won’t idle engine dies

I have 1990 olds cutlass supreme that has been having idling problems. It won’t idle at all now, once the engine get warm. It is a 3.1 engine. Do you think it could be a sensor problem?

2002 olds van multi-function switch

2002 olds van, lower brake lights, traction control and cruise control not working. Have tried new brake light switch, cruise control module from a salvage yard and still not working. Have been told by several mechanics it was probably multi-function switch but have also been told if turn signals are working it wouldnt be that either.Any ideas
