can anyone help to decipher these vague instructions please
i dont see a hole as the instructions describe as to insert a nail
to hold back the paw so i put the nail next to the paw and it is
in the disengaged position but then i am completely lost on what to do next -i put new pads and rotors on the rear and the parking brake is
extremely tight so it takes a lot of force just to reach the first notch_
these instructions are so vague that they say to remove the seat cushion
but it is actually necessary to remove the entire seat so i dont think these
instructions are very good yet they are the only instructions i can find
in this forum or on the internet and i dont have a service manual_
thank you please help me

instructions are from another thread posted on this subject copied from theautozone website

The parking brake lever/cable adjustment is automatic. The adjuster must be disabled to create the necessary cable slack for certain service procedures. Following these procedures, make sure the adjuster is properly enabled to assure correct parking brake operation.

To disable the automatic parking brake adjuster, proceed as follows:

Remove the drivers seat cushion.

Remove the parking brake lever cover and screws.

Using a suitable offset tool, disengage and hold the drive pawl from the drive sector.

Insert a nail or drift through the hole in the anchor plate to retain the drive pawl in the disengaged position.

Move the parking brake lever until it aligns with the lock pawl.

Depress the button on the lever and move the lever to the down position.

Verify the anchor plate is against the stud on the parking brake lever, if not as specified, repeat the procedure

To enable the automatic parking brake adjuster, proceed as follows:

Remove the nail or drift pin from the anchor plate.

Apply and release the parking brake 3 times.

Pull up on the parking brake lever. Proper adjustment will result in the lever moving 3-5 ratchet clicks with a force of 61 lbs. (270 N).

Release the parking brake, there should be no rear brake drag and no gap between the caliper housings and caliper parking brake levers. It may be necessary to remove the tire and wheel assemblies to see the caliper housings and levers.

If removed, install the wheel and tire assembly.

Install the parking brake lever cover and screws.

Install the driver's seat cushion.

If Im reading it right, that link is for drum brakes. OP doesnt have drum brakes.
Did any C4's have drum brakes?

And the OP has a link to the same article. They have clearly been searching.
I would love to help them, but I have no idea. Have not had to do brakes yet.


OP: the instruction clearly say to remove the seat frame, not just to cushion.
But I agree that at step 2 the give no details.

You need to seat bottom and cover off parking brake to get access to lever assembly.
The lever uses a gear and a paw for adjustment. #5 is the pawl for gear you need to use a screwdriver or small prybar to lift pawl off gear so it can rotae back. #9 the pin or screw is installed to hold pawl off gear so the cable will release and give slack Press button and put handle all the way down. With the pawl off the gear and the lever all the way down cable should not be tight. Parking park should be fully released. If pistons weren't turned all the way in prior to installing pads brakes will drag. If cable is still tight someone may have misadjusted cables under car where right & left rear cables attach. There is a threaded rod made to one cable and a nut on a bracket on the other. If the threaded rod is deep in the nut it most likely misadjusted and needs loosened. Remove #9 pin and actuate handle at least 3 times now it should be adjusted. It seems this is a good subject for a video.

I hope that works thank you Kevovo _the reason it is so tight is because I
installed Brakemotive rotors which are thicker than stock or the equivalent
I will let you know when I get her done_

no i dont think any C4s had drum brakes which once again makes you wonder about these instructions

thanks this is the thread i never found i could have used it before
- i just now put the seat back in and said screw it i have one notch
and that is enough i will just wait for the pads to wear down for the second notch -

I agree that the FSM leaves a lot to the imagination with their description of vague parts. I never was able to figure what the hell it was trying to say. My lever worked perfect until some moron gorilla at the state inspection station tried to rip it out of the floor. He pulled it up so hard I'm surprised the arm didn't break off. Then he couldn't figure out how to release it and then got it totally screwed up wrestling with it. By the time they finally told me it was "stuck", they had pretty much warped the whole damn assembly to where I don't think the FSM procedure will even work any more.

grassyflats

you can fix that - the problem is i follow instructions perfectly to the T
but you cant find any decent instructions to do the job anywhere at all
pry off the paw yea right you cant even pry off the handle - i figure they
do this on purpose so you have to take it to the dealer even the local
mechanic is going to be like wtf and i bet the mechanic at the dealer too
the only mechanics who can do this job are mechanics who have done it
before and have been taught how to do it by guys who have done it before

-84 to -87 had drum brakes for the parking brake inside the disk brake, just like Saab from about -93 and forward and Chevy Silverado around -00/-01. Two examples from my world. :-)
And if you ask me, a much better construction than the disc mounted parking brake on the -88 to -96 C4.

I replaced both my rear cables when I did the brakes, it's a real bitch but if you read the instructions while looking at and working the lever things will start to make sense.

I changed the wires (cables, which is the right term?) but it was a bitch and that bitch was screaming and fighting all the time. :-)

The new (AC Delco) wire to the right rear wheel was two inches short and the nipple was to big and had to be ground to fit the joint.

The lack of length on the rear wire got fixed with a longer "middle wire". Or actually it isn´t a wire, it is a turnbuckle so I can adjust the total length of the wires = the movement of the parking brake handle.

I have some pictures that I will post tomorrow but it´s late now, 20 minutes after midnight, and I must get at least some sleep. :-)

Yep, the AC Delco cables I ordered had a too large crimped cable stop too, no way it would have worked without mods, I just ordered a different brand. Keep n mind folks if you ever replace the rear brake cables.
