I got update regarding brakes. Today at a speed of 25 mph. All of a sudden ABS light stopped glowing. I thought oh, good, it fixed itself. Then I heard from pedal area noise of sizzling, literally it had a same sound when you fry a patty. When I removed leg from a brake, sound stopped. Then when I tried to apply brake again. Pedal started kicking, sometimes it was soft sometimes hard and everything happened in a second. Then sizzling sound again, then stopped. Then Abs light came back. I took highway, 40-50 MPH, as usual no hiccups. Abs light is still on. What the hell was that?

The soft then hard pedal feel sounds like air in the lines? Have you bled the brakes and replaced fluid yet?
I still think the ABS light is due to a failed module

I got this switch today. Will try it on. And a will order new pads and will change brake fluid. I haven't changed brake fluid and never blended the brakes since I got it. And I haven't opened brake fluid reservoir even since

What part is this?

I had issues with the ABS module that is located on the frame rail of the truck. I think this is the part:

That is brake switch for a brake pedal.

I replaced brake light switch and red park light is gone. Abs light is still there. Probably I will go with cheapest option from Rock Auto. At least it's New. And core is just 50$

This SHOULD fix your abs. There are 2-4 weak solder points on the board that break and cause the issue. The one plug is a pain to get to but it’s easy enough.

So basically what you are saying is , not to rush with replacement, but solder it by myself?

Go for it! Here’s a video for it! I’m all about a DIY repair. Especially if it gets the light to turn off for a short while you at least know the root cause.

I decided to check upon my dot 3. It smells like bog. I don't know how to bleed brakes. So I used a syphon, and added new Prestone dot 3 max. Filled reservoir till max. And then started vehicle and pumped brakes few times. This is cool in reservoir after I changed it. Probably I will do a procedure few times and then go to repair shop for new pads and properly bleed them. And flush brake fluid again. I just want to do what our shop will not do. They never washed brake lines, they never wash engine. So I will buy some 5w30 pensoiol and wix filter. And do procedure again. Just waiting for abs module to show up. I decided not to take it apart , and go and order the cheapest one from Rock Auto.
