Rear drums, Self adjusters, "self" as in yourself

Now how exactly do these things work?  When do they work.  Am I supposed to drive very fast backwards and slam on the brakes?  Thats what all the old farts and rednecks tell me to do.
 
Tonight I had to replace a section of brakeline.  Looks like some dipwad had made a previous repair and used a compression fitting, and not reattached the rear hose to the car.  So it eventually broke.  While I had it apart I checked the clearance of the drums and they where waaay loose.  I used a brake spoon and pulled them out alot.  Car stops 100% better.  But when am I going to have to do this again?
 
 
Oh and Compression fittings are for coochs who are afraid of a double flaring tool.  :mad: :mad:  Thats my number one pet peeve.

i agree on the pressure fitting thing. anyway, their is a wheel on the drum you turn to adjust them outward. this is sopposed to be kept set by useing your emergancy brake, which now you should be useing alot sence you swapped to a 5speed. most auto cars never touch them and their brakes get out of adjustment, or the ebrake freezes up from never being used.

Well i just did a complete brake replacement repair on my 86TC and wondered the same thing about the adjustment on the rears so i googled it LOL. went to how things work and it shows an animation of the rear drums and how the adjusters work. its all adjusted by going in reverse and pumping the brakes slowly as long as everything is functioning right and " LOOSE"

THey should just auto adjust as the pads wear.  If you were able to adjust them and the little cable is still there they should be working.  Did you pull the drum off and inspect?

Yup, Chuck all looked well inside.  I've reshoed many rear drums to know what to look for and to know that mine were ok.  The little paw on the self adjuster was clicking when I rotated the adjuster. 
 
Nate I thought that only rear disk adjusted that way.

I was just explaining how the rears automaticly adjust. But if i were you i would just remove the little black rubber plug on the back of the drum and adjust the drum as you spin the wheel to get it adjusted correctly.

I have been adjusting our '88 TB rear shoes for a couple yrs now. It just seems that the self adjusters have gone on a permanent vacation.  I did replace the star wheels. The teeth on these get worn down and perhaps cease to properly engage the tang that moves downward to adjust the shoes.  In a week I will be looking at the rear drums and have another question on brakes I will post.  I just figure that a 18 yr old brake set up is having a senior moment?  A mechanic told us that on my sister in laws '95 Pontiac--it is imperative to use that E brake to adjust the rear calipers. That was strange to me--as I never would have thought that any E Brake had anything to do with brake adjustments.

That is the same with the Cadillac rear disc that is a popular disc swap for the mustangs. They say if you don't use your ebrake everytime you park it will get out of adjustment and cease working.....

Sorry cougarSE must have missed that LOL

Yeah Demented, For our GM friends, I say, when in doubt, use the E brake.  Ask me how much I paid to have sissy's rear GM brakes worked on because the calipers froze up?  Let's say --lots more than I have ever spent on our own Fords over the years--and she blew a tire to boot.  Last month her rear strut broke as well.    Mechanic said ---bad GM design on the Grand Prix rears in our case.  Right now her E brake cable is messed up and I will have to take it in again because I am not comfortable working on someone elses brakes.  I spend more money on her car than both of our Fords--and our Fords are 6 years older in both cases!

theres only 3 ways, you do it urself by turning the little wheel thing with teeth on it, or you back up and apply the brakes, or use ur parking brake, every cars different...
