Parking brake advice
 
Just fitted new rear discs and parking brake shoes.
I wound out the star adjuster till I could just slide the disc on to the hub. Auto box is in neutral, so is transfer box. Thing is, when you tun the wheel you still turn the drive train. It's not possible to "feel" the shoes as they drag on the disc because of this. ( well to me it's not !)
Any tips for this job ? I've got about 4 clicks on the park brake lever and during the annual car test they do check the Park brake efficiency so it has to be set up well.

Thanks

Isn't there a length adjuster in the middle, with cables from that going out to each wheel?

The obvious question would be whether it worked before you touched it. You might have installed the wrong shoe, installed them wrong, etc., since you'd expect the parking brake to be tighter after new shoes.

Presuming you definitely installed everything correctly and checked that against either a factory or aftermarket manual or google search, make sure they don't drag, then you may be able to take up the slack if you have that common adjuster in the middle of the vehicle...

Sorry, should say they are working (as we speak, the jeep is still on axle stands) but I want to set them up correctly so the don't drag while I'm driving but bite hard when I pull up the park brake lever.
Just asking if anyone has a method they use to set them right ?

Did you use the method from the manual?

Well I dont have a gauge like that to use. Like I say, I set the shoes so I could just slide the rotor back on, so assume there is no drag at that point.
I'll give it a road test on a hill and see if they hold the jeep still !

If I read Frango's doc correctly, you would want to have somewhere between 1/64th of an inch and 1/128th of an inch slack between the shoes and the drum.
Using 1/128th, thats just over 7 thousandths of an inch.

If you have any old computer punch cards, you could bend one in between the drum and the shoe and hit that value so close it would be scary. Adjust till it just barely can be moved. The advantage of this method is that it can be moved along the shoe to make sure there is no too tight spot or too loose.

Ordinary tablet paper varies quite a bit, but a single sheet folded tightly in half will come in just a bit too thin, so you'd go for a slightly looser fit.

Make sure you can slide a folded tablet sheet all around the shoe, so you get only a bit of drag and never a tight spot.

You might be able to eyeball this thin of a clearance, you do not want much at all, but you also do not want it to touch.

Finished the job, so that was a new rear wheel bearing and seal, new rear discs, pads and park brake shoes.

The park brake will hold the jeep firmly on a hill (pointing up or down) even then the engine is running at Idle and the box in drive, so Im happy and it should pass inspection.

But it does take 6/7 clicks on the lever to achieve this. Does that sound a bit much travel, should I turn the star adjust out another click do you think ?
