Front brakes Dragging

['94IDITurbo7.3]

I vacuum bled my brakes today in school and my right rear wheel cylinder took a dump on me. so tomorrow i will be fixing that.

See what i'm sayin about i work on it and something happens.

do yourself a favor.
After vacuum bleeding the brakes, get someone to step on the pedal while you bleed them normally.

I like that guy's post somewhere around here about using one of those pressure-oiler cans to force-bleed new fluid from the bleeders up.

Ckalk it up to experience. Before long you'll be a brake expert.

Ya same thing w/ my fuel system i have had the injectors out about three times in that many months along w/ my IP. i'm no technician yet but i got the fuel system down pretty good. but i enjoy learning about cars b/c this is what i want to do for a career.

Bleeder ports are notorious for seizing up and then you snap them off when you try to open them. A suggestion I would make to eveyone, is to take a few seconds to put some neversieze on them when they are new just before you install them. This, and perhaps cracking them open once every few months will keep them from giving you grief when you least expect it. The same could be said for the nut that attaches the brake line. That thing will become a break line and not a brake line if the line siezes up in the nut.

yesterday in school i did look @ the brake lines going to the rear wheel cylinders and they look like new. they are nice and clean and have no kind of rust on them so hopefully they will just come right off. but lets not jinks it by talking about it too much.

X 2 on the anti-sieze.


Also, at least four times a year, and any time that I find myself under any of our trucks, I saturate every brake-bleeder, every brake-line fitting, shock mounts, U-bolts, anything threaded that I might ever want to take apart, with whatever can of knocker-loose I happen to have at hand.

It sure pays off anytime I have to take something apart.

Heres an update

Yesterday in school i pulled of the drums on both sides and discovered that my rear diff decided to be nice and share some of its gear oil w/ my rear brakes.
So i got new axel seals for both sides.

on my left rear the shoe material was about 50% gone.
My right side was a bit more interesting. my teacher and i beat on the drum w/ a dead-blow hammer and got it loosened up but it would not come off. to day when i got to school he told me that they got the right drum off. so i go in the shop and it is in about 4 peices. i then took the hub off and discovered that the auto adjuster was adjusted out so much that it almost came apart and was jamming the shoes against the drum. because of this the shoes, which were completley gone by the way, had turned themselves into a lathe. this created about a 1/8" lip on the drum preventing it from sliding off. so after school i got a new drum.

I have got 2 new wheel cylinders, new hardware kit and spring kit, & of course shoes.

after discovering all of this i am pretty sure i was running only on my front brakes. hopefuly fixing the rears will help w/ the fronts. i think someone that participated in this thread said that rears that are adjusted wrong can make the fronts do funny things.

I wll try to post some pics of the carnage!

This is a auto shop teacher? And he broke the drum getting it off? That doesn't sound good. Why didn't he take a brake adjuster tool and turn the adjuster in through the access hole in the bottom of the backing plate to bring the shoes in?

 

['94IDITurbo7.3]

actually it was kids in another class that broke the drum.
b/c of the shoes being totaly worn down the adjuster ended up adjusting itself totaly apart and it was jammed up so there was no possible way to get the drum off w/o breaking it.
when my teacher first told me they broke the drum to get it off i was kind of pissed but then i looked at it and there was no other way.
next monday of tuesday when i bring my old drum home i will snap some pics that show the groove that the shoes had carved preventing the drum from sliding off like it should.

I most likely could have gotten the drum off without breaking it apart; however, on nine out of ten vehicles, the star-wheel adjusters have been so neglected that nothing short of three weeks soaking in knocker-loose is gonna move them; plus, on most of them, the little teeth are so worn away that no brake tool is gonna get purchase enough on them to rotate the frozen adjuster.


All mechanics that are working on other peoples vehicles don't take pains to do such things as wire-wheel-brushing, thread-chasing, and applying anti-sieze to the threads, let alone taking a triangle file and sharpening the teeth.

They just slap things together good enough to get the job out the door and let the next guy worry about it later.

the way the adjuster was oriented in the drum there was no way to get at the star wheel.
we were going to grind away the heads of those nail looking things that go through the backing plate in hopes of getting all the internal parts to collapse and release the drum, but the heads were flush w/ the backing plate and i didn't want to screw that up to.

I've had to cut out "windows" in a brake drum and use an air chisel to collapse the shoes inwards before I could get them off. This was on an Explorer 8.8 with the drum parking brake inside the disc hat. Sometimes that's just how it goes down.

Sometimes it's a time thing, sure I could have spent 2 weeks figurig out a way to get them off, or I spend $50 and buy new rotors and have it done that afternoon. I wanted to go wheeling, so they got cut.

Another Update

Got both rear brakes put back together just need to put the hubs on and then then the drums.
Then bleed the system and hope I have good breaks
