Rear drum brake job

[Daniel]

Hi,

Due to a sticky wheel cylinder and a roaring noise while driving



I have to make the complete job: drums, cylinders, shoes.

Pls correct me if my rebuild sequence is wrong somewhere.

1) with all new pieces in place except drums I release parking brake adjuster nut till shoe lever stop is against edge of shoe web.
2) With drums and wheels fitted, system purged, I step on brake pedal till I don't hear the adjuster clicks anymore.
3) With parking brake released I set the adjuster nut till wheels are hard to turn by hand.
4) I release adjuster nut to freeing wheels.

Is that right?
Something forget?
Some special tricks to know?
How many clicks for the parking brake?

Tks,

Daniel

i don't think our rear brakes are self adjustable so you'd have to adjust the shoes by screwing the adjuster nut on the axel between the two shows till the drum can barly fit

e brake adjustment is just as you said

The rear drum setup is "self-adjustable", but it does so in a very poor way. The way I was told to adjust rear shoes on the Kadett/Nexia (by mechanic), was to set the adjuster by hand to the point, where the drum was turning with a little of restriction. If you set too much friction, shoes will keep constantly rubbing on the drums and cause overheat. Then drive the car and perform about 10 slow-downs from 60km/h to full stop. Then, drive the car backwards, and press the brake HARD number of times (10 or so) until the car comes to stop. I went through this procedure a few times, and it worked quite well. Don't forget to bleed the entire system, if required.

Oooooookay.
Thanks for your advices. Because I was quite "uncomfortable" with the procedure described in section 4E "brake adjustment". It seemed to me that something was wrong in the description.

Well. The job is done with the following mods with the help of GsiTurbo.

1) with all new pieces in place except drums I release parking brake adjuster nut till shoe lever stop is against edge of shoe web.
2) With drums and wheels fitted, system purged, I step on brake pedal till I don't hear the adjuster clicks anymore. Took about 30x.

Here comes the trick from GsiTurbo: "Then drive the car and perform about 10 slow-downs from 60km/h to full stop. Then, drive the car backwards, and press the brake HARD number of times (10 or so) until the car comes to stop."

3) With parking brake at second click turn it's adjuster nut till shoes just drag on drums. Check that maximum lever travel is about 6 more clicks.
4) Release parking brake and check for free rotation.

This would make a great "How-To and Modifications"

I have had a look to the Espero service manual that "canvas" has put on rapidshare . The drum brake adjustement is so straightforward that I'll adopt it.
