diagnosing front disc brake issue

[WagonCrazy]

I bled more than a quart of fluid thru all 4 lines, till it was very clear and no bubbles. I'm sure I have all the old fluid out of the lines. They are only 1/8 inch lines...so not much volume.

I could have just started by bleeding the lines, but I think I would have ended up pulling and inspecting the MC and prop valve anyways, so I just chose to get it over with at the start.

Hope you solved it Paul. I'd just out of curiosity like to understand what the problem was and why the brakes were pulsing off and on. I'm having a hard time seeing how "bad" brake fluid could make that happen.

Well guys, today I went for the one aspect of the brake system I haven't looked into ...the rear brakes.
Bingo...

Lining of the shoe(s) was coming off. Yes...it started to squeel when driving it this morning. That was the final clue...

I installed these rear shoes 4 or so years ago, and don't remember where I got them, but they are CHEAP JUNK. They are "bonded only" to the metal shoe. So they let loose with less than 5000 miles on them.

New shoes installed are better quality with rivits holding the material to the metal shoe.

So I got a round trip accomplished all thru my brake system, only to find it in the last place I looked.

Didn't Laszlo ask me that question at the top of this post??????

Dumbazz Paul.
