LW-200 rear brakes / E-brake

    Any pointers on where to find the adjustment for the e-brake on a LW-200?
    I can't find any adjustment on the lever inside, so it must be under the
    car right? It doesn't have self-adjusting rear drums does it?

    Should be easy enough to tighten up by lifting the rear wheels and sliding
    under if it is visible. I assume I would be looking for a y cable coming
    from each brake drum to the center of the car with the single cable going
    forward to the E-brake.

    Why would it *not* have self-adjusting rear drums? Self-adjusting drum brakes
    have been around for more than forty years -- I'm guessing probably a lot
    longer than that, but the oldest vehicle of which I have first-hand knowledge
    is a 1967 Plymouth Fury.

    I'm having CRS (it is after all, my 57'th birthday today...)
    I vaguely remember that the E-brake adjuster on my lw300 is through a 3/8"
    diameter hole in the outside of the disk/drum assembly. The wheel has to
    come off and there is access to a star wheel through the hole. Since this is
    not a service brake, I guess they figured that it wouldn't need to be
    adjusted much. Who Knows.
    I have the service manual for my car. If you still need help, ask. I can
    scan and send you a drawing. You may contact me at

    Why? I don't know. Heck, I just realized it wasn't 4 wheel disc about two
    weeks ago while rotating the tires and explaining to my son (7) how to
    break bolts loose and tightening star patterns.

    I had a full size E-250 Ford van that had self-adjusting rear brakes.
    But it also stated this in TFM. I did not seeany mention in the Saturn
    Lw-200 manual of self-adjusting rear drum brakes.

    I have tried a few sharp stops from about 3 MPH in reverse; didn't hear
    any clicks or ratcheting - any the E-brake seems no tighter; the car
    still slips a bit on my driveway.

    ....that is why I asked.

    As long as it does not roll more than about a foot (worst case) on a hill,
    it is normal for this design it seems. One of the rear wheel links (can't
    remember if it was the upper or lower...) is a trailing arm that goes to a
    VERY loose rubber bushing in the frame. I thought something was wrong when I
    first applied the e-brake on a hill and the car drifted as soon as foot was
    taken off the service brake. Was just the wind-up in the trailing arm
    bushing.

    btw- this bushing is so loose that if there is any brake dragging (I have 4
    wheel disc with abs), it will throw off the rear wheel alignment and eat
    your tire. One of my rear disc pads was rusted into the caliper and wasn't
    moving right. got that fixed but needed a new tire before I could get a 4
    wheel alignment.

    Just realized you said you do not have four wheel discs. four wheel disc
    brakes with ABS have a separate drum brake for the e-brake.

    As long as self-adjusting brakes have been around, I'm surprised that *any*
    manufacturer even bothers to mention it any more.
    Please understand that this can happen even if the brakes are perfectly
    adjusted, and the e-brake cable *isn't* -- in fact, given your description,
    that's probably exactly the case.

    Wait, so if I have traction control and ABS then I do have 4 wheel disc
    brakes, but they have a secondary drum for the e-brake?

    Now I am really confused.
    Anyone know details on the clutch in this car? It is going to need
    replacing soon. Ugh.

    Where is the preferred adjustment to the e-brake cable.
    Inside the car? Underneath?

    I don't just pull up the e-brake, I yank on it.
    A good 7-9 clicks. The car will continue to creak backwards down the
    drive. Leaving it in gear provides enough additional resistance, but I am
    sure the e-brake cable could be tightened a tiny bit without dragging and
    still provide the holding power on the hill.

    I really meant to send you that information this past weekend. Too many
    honeydew projects that took priority...
    All of the 4-wheel disc ABS systems I've seen have a separate drum for the
    e-brake. If you tell me that you have rear drums - and are sure of it, I'll
    send you that information.

    Generally, you never adjust the e-brake cable. You adjust the star wheel
    only

    First off there are no 'emergency brakes' to be found on any Saturn. The
    DOT does not require them on cars. (IOW no one should let their service
    brakes reach a point that they can fail.)

    The L series had either rear disk with with a drum parking brake or
    simply drum brakes in the rear.

    This is how you check adjustment, not make adjustments:
    ========================================
    Park Brake Adjustment Check

    On new vehicles (less than 50 miles) and on vehicles which have
    just had the rear brake serviced, before performing Park Brake
    Adjustment procedures, apply and release the brake pedal 20 times. This
    allows the adjuster to position the brake linings and prevents premature
    wear of the brake linings due to improper park brake adjustment.
    1. Raise the vehicle on a hoist so the wheels spin freely. Refer to
    Lifting and Jacking the Vehicle in General Information.
    2. There should be no drag at the rear wheels with the park brake
    lever in the rest position.
    3. Pull the park brake lever to the third click. There should be
    heavy brake drag to no rotation at both rear wheels when turned by hand.

    Important

    If both rear wheels do not exhibit similar drag in step 3, check
    for damaged or incorrectly installed rear disc or drum brake assembly
    installation of drum assembly components, park brake cables, and/or park
    brake lever assembly. The park brake is adjusted correctly if it meets
    the specifications explained in steps 2 and 3.
    4. Adjust if necessary. Refer to Park Brake Adjustment .
    5. Lower the vehicle from the hoist.
    ========================================

    OK, not an 'emergency brake' but a redefinition of terms to 'parking brake'.

    Some of us were around back in the day of single circuit braking systems
    where a burst brake line **did** require and emergency brake. Now we have
    dual circuit braking systems where, if one fails, there is still a redundant
    one. Old habits are hard to change. Besides there was some drama and
    excitement in saying *emergency brake* <smile>.
