Too much time on my hands, aka don't feel like doing yardwork.

Handbrake adjustment:

1. raise both rear wheels off the ground

2. release handbrake lever

3. pry boot up & loosen cable adjuster nuts:

4. remove one wheel lugbolt (not necessary to remove wheels)

5. insert medium flatblade screwdriver into lugbolt hole

6. engage blade into teeth of brass star adjuster wheel

Note: When facing the left rear wheel, the star adjuster is approx. at the 4:00 o'clock position for an e32/e34. It is at about the 2:00 o'clock position for an e36.

For the left wheel, push the end of the handle sideways to the left (toward the center of the axle). This will rotate the adjuster wheel in the opposite direction and will expand the shoes toward the drum. May take 6 or 8 clicks if it's been awhile.

Turn the wheel periodically to tell when the shoes are making contact with the drum. When you think you have it, pull up on the handbrake to reset the shoes, and release the handbrake all the way. Turn the star wheel a few more clicks until it's firm. Back off in the opposite direction 2 clicks.

Repeat on other side. For the right wheel, the star wheel will be at approx. the 8:00 o'clock position for an e32/e34, 10:00 o'clock for an e36. Pry the screwdriver AWAY from the axle to expand the shoes. Adjust the firmness the same as for the left wheel.

When done with the wheel adjustment, tighten the handbrake cable adjuster nuts as evenly as possible until it takes 4 clicks of the handle ratchet to set the handbrakes. Some cables have a single nylon locknut, others have a 10 mm nut with a smaller 9 mm jam nut.

The shoes may drag for a little bit but that should go away by itself. If they are too tight, loosen the star adjuster(s) another click or 2 or repeat the cable adjustment.

Those are "Donco" specials. Like I said, too much time on my hands & didn't feel like doing yardwork

my hanbrake is hopeless.....when i apply it say to do a hill start or if the car is rolling forward slightly i can feel the left side of the car raises more than the right,so i guess the left wheel has "more " handbrake than the right...??

I adjusted mine a while back, back when I replaced the cables and brake shoes. It would grab nicely for a while (4 clicks to hold the car) but now its back to usual. I want it to grab well all the time. What gives?

Thanks Gale. We now have no excuse to drive around with blocks of wood in the trunk.

Yeah I was going to say with Don being an engineer, I have a feeling those photos werent fetched off of the internet :)

Thanks Don, wish I had these the first time I disassembled my parking brake back when you were helping me but I got through it okay.

When I was rebuilding the rear end, I hadn't put the parking brake back until I made sure everything was working.

One day, I was teaching my lil sis to drive, and first had to explain that "In drivers ed, they tell you to first remove the parking brake. Unfortunately, this car has no parking brake. Park on something level. "

Nice write up Gale.
Now perhaps a tutorial on the handbrake turn.
Shouldn't you be making good on that badge taped to the rear of your car?

Working on it. Still need to send the turbo in for a full rebuild, $575 is the best price I found so far for new impellers, new shaft, new center bearing, & full dynamic balance. Things are going about half-fast at the home front (not to be confused with half-assed). Got too many projects ahead of the turbo job, but it will be nice when it gets done. Hoping for about 100 bolt-on horsepower. Any more than that will be frosting on the cake. :D
