Re: Rear left wheel locked up

By cover you mean the brake drum?

You may need to turn the adjuster. The toothed (looks like gear teeth) device between the brake shoes at the bottom.

To make it easier to install the drum, turn the top of the wheel with teeth away from you.

There is an adjuster on the toothed wheel near the top. It is much easier to turn if you pry the out a little so it is not setting against the teeth.

After you have turned the wheel enough to get the drum back on you must then adjust it so the brake shoes are very near the drum.

With the drum installed, use a brake adjusting tool, or a flat screw driver, to turn the wheel through the slot in the back side of the backing plate. The drum should turn with very little or no drag from the brake shoes. I usually adjust the brakes against the drum then back off until the drum turns fairly easily. Do this on both sides.

Yep, I read the last post which struck me as funny. Sorry, no intention to offend. As usual, the joke's on me.

I Did That Just Now Verle But The Drum Still Wont Fit On. I Also Noticed That There Is Almost No Wear On The Pads, Where As The On ThePassenger Side There is, Could This Be My Problem?

You need to look at the picture Verle posted and make sure your brakes look exactly like that http://api.viglink.com/api/click?for...FP1020008.jpge pic.

if your shoes are adjusted properly. Your emergency brake is hung up some where. If it is hung up it might have disconnected your brake hardware. You could remove the e brake bar between the shoes temporarily to try and diagnose your problem. Good luck Rob

Not exactly. That is a picture of the front brake. He's working on the rear. His should look like the one pictured on this link.

Checking the emergency brake cable is also a very good idea as another poster said. When they get old they fray and or seize inside the housing.

Re: Rear left wheel locked up

Check to make sure the adjuster is turned all the way back in. Also make sure the shoes are even with each other like this ( ). If one is off center the drum wont go on. Finally, it may be necessary to loosen up the parking brake cable adjustment as well. If rust isnt much of a problem where you live, then loosening it up shouldnt be too much of a problem. In the rust belt, you might as well pack a lunch when it comes to loosening up the parking brake cable.

Re: Rear left wheel locked up

I would assume when the drum was off you made sure to turn the axle ruling out a bad bearing. If not do so. Also push the wheel cylinder pistons in by hand to check if one is size in the bore. Not a whole lot that can go wrong there just make sure everything is working as it's supposed to.

Really strange problem you report.You say left rear wheel locked up and then you say the right rear has more wear than the left rear.Its possible that whoever did the last brake repair ( clue:shoes with almost no wear)installed something wrong.A picture would help figure out the problem.
Check the emergency brake adjuster, if it's threaded all the way in loosen it up and see if it now slides on.
Also just so you don't confuse people rear drum brakes have brake shoes, disc brakes have brake pads.

Re: Rear left wheel locked up

This may not solve the problem, but if the shoes are worn unevenly wouldn't it be a good idea, and cheap insurance to go ahead and replace them? That way once you get everything figured out you would have the piece of mind that everything is new and correct

Cool costs money. How cool do you want to be?

Re: Rear left wheel locked up

Take everything off. While it's off, make sure the axles turn to rule out seized bearings and bad stuff inside the rear end housing. screw the adjuster assemblies all the way in then put it all back on again so it looks like BillL's pics above. Slip a drum on. Notice how it just sort of falls on. Pull it back off and adjust the adjuster (heh) some, then test fit the drum again. Keep doing that til it won't go on, then back off a little. You should hear a little scrape when you turn the drum. Now do the other side just the same. Once both sides are like that, screw on a couple lug nuts on each side to hold the drums straight and have someone press the brake pedal while you try to turn the drums. If they are both free when the pedal is released and tight when the pedal is down, you are almost done. Test the parking brake. Bleed the brakes while it is up on the stands. This is usually good enough to move a car around in the driveway or in and out of the garage.

If one brake works and the other doesn't, try to bleed them. One wheel cylinder may be seized. If fluid comes out the one that doesn't work when you try to bleed them, then that is what is wrong. If you can't get fluid from the one that doesn't work, then you have a bad axle line. Check it for dents and crimps. On a 40 year old car, you should have in your plan of stuff to do, at least new rubber brake hoses and probably new rear brake lines. You don't have to buy them, you can make them from pieces of tube bought at the parts store. Should be several threads here about how to do it.

I didn't see mentioned whether the car is a driver or a "back 40" car dragged out of the weeds that you are trying to get drivable. Different things wear out from sitting than from driving.

Well, THAT used up all my words for the week.

Re: Rear left wheel locked up

Sorry to say but unless Mike comes up with a couple of pics of the problem side he's never going to get any real definite answers.

Re: Rear left wheel locked up

Could be the light when the pic was taken but the left side backing plate edge looks shiny like it could be hitting the drum and when you tighten the wheel down it locks up. Sure you would notice something like that just thought I'd throw that out there.

Those are pics of my car I posted for reference for Mike, who started the thread. They aren't of the problem car.
