Where is the brake light on and soft brake pedal?

Proportioning valve next to the master cylinder is detecting low pressure 2. At the same time, the abs controller gets a signal from the PCM that there on by itself just from the VSS sensor in the differential being bad… to activate the BRAKE LIGHT SWITCH on the proportioning valve.

Why does my brake pedal feel so soft?

The final reason why your brake pedal may be soft is because your master cylinder is failing. A master cylinder may fail due to age and wear. The master cylinder is the main valve that pumps brake fluid into your brake lines. When the cylinder is failing, your lines do not get the brake fluid needed.

Is there fading brake pressure, no fluid loss?

I could pump the pedal to get pressure but as I applied steady pressure the pedal would sink to the final 2 inches (slowly and with moderate pressure). With the engine off the pedal is firm (does not fade). No fluid loss. I -properly- bled the system thoroughly with no improvement.

Why does my brake light and ABS light come on?

Yesterday her brake light and ABS light came on. The pedal seems to be going down further than it should. I checked the brake fluid, it was fine and I couldn’t find any leaks.

What does it mean when your brake light is on?

When you are parked in a safe place, press on the brake pedal as hard as you can. If the pedal slowly sinks to the floor, it indicates you either have air in the brake system or the fluid is leaking out. If the pedal holds steady, you probably don’t have a leak and can move on to further steps below.

What happens when you press the brake pedal?

When the brake pedal is pressed, the brake fluid is pressurized in the brake lines and hoses. The pressure in the brake hoses forces a piston in the brake calipers to extend.

Why does the brake light come on on my Dakota?

My daughter has a 2001 Dakota. Yesterday her brake light and ABS light came on. The pedal seems to be going down further than it should. I checked the brake fluid, it was fine and I couldn’t find any leaks. Any ideas where to start now?
