My assumption was you continued to drive the truck with half functioning brakes, which is true. I knew you would take offense. Sorry you consider this rude, but I stand by my assumption. Good luck.

 

I find this amazing! A degree says you completed schooling in a certain field. Big deal! Does it say you know what you are doing? Obviously not if you come here asking for advice. Now before you get up set and attacking me for expressing my opinion. It's just that. My opinion! Nothing against you! When i was in junior high i was turning wrenches and taking things apart to figure out how they worked. You went to school for it and don't. I don't get it. This is a perfect opportunity to learn outside the book literally. You will learn more doing than you will by reading a book or listing to a teacher. So i guess breaks have nothing to do with automotive technology. Shame on the teachers and whoever gave you a piece of paper for a wall ornament! Personally i would be upset and concerned that they didn't teach you this stuff.

 

I don't trust the ol Joe mechanic to work on my brakes on my 15 year old truck.

 

The proportioning or bias between front and back is not adjustable. It is built in and I think is part of the M/C. I can't recall as I'd have to look at mine or a picture. If so, then I wonder if the wrong M/C was installed.

Was the accident on drive pavement? Dirt? what?

How exactly did you confirm the fronts are not engaging? Spongy feel is indicative of air in the system. Maybe there wasn't previously, but the system may have found a leak path from the brake slam session. Any fluid showing from inspecting all visual spots of the brake lines?

Condition of the brake pads? Maybe they are too thin to touch.....? lol

2001 has dual calipers up front.

Not possible, Heard a low grinding noise from my fronts just in time to catch them plate to rotor. One thin line. turned the rotors. no problem.

 

So, I looked above the fuel tank where others have said that the line breaks and leaks sometimes. Looks good! No leaks anywhere that I can find. Bled them in the proper order. No change!!!. The front brakes do move, but cannot properly test the pressure that they are clamping with the tools I have. I think it may be 1 old calipers, 2 old rotors, 3 old Rubber brake lines, 4 improperly adjusted rear brakes. I don't think it is one single issue but a little bit of all. My brake fluid is nice and clear, no bubble and not a hint of air in the lines. What do you guys think?
The I don't understand this system. Doesn't make sense to me. What am I missing? I have built two entire hot rods ( a 52 Chevy Apache and a 49 ford coupe) built the entire brake systems on those but can't find a single major issue with my truck.
Would a worn self adjuster on the rear brakes cause this issue?

 

The so-called "self" adjusters on these trucks don't work as well as they should.... some folks make it a habit to re-adjust their rears at every oil change..... yeah, they are that bad.

If the rears are WAY out of adjustment, I could see them giving you a low pedal..... I don't know about total failure though...... couldn't hurt to adjust them up....

 

You did check to see if the master cylinder wasn't leaking right?

 

I checked for leaks everywhere. There is no fluid on the M/C anywhere and the components under the M/C has no evidence that it has leaked. Ever

 

May have blown internal seals on the M/C.... won't necessarily leak.
