Hi all,

Just got my car. Seems I need to push the emergency brake almost through the floor board to get it to do anything. Is this normal? Or does it sound like I need an adjustment?

Is it easy to adjust?

I don't have any 'clunking' mid-way. Just need to press it hard to get any sort of braking.

honest, its the same......long travel = adjustment required try one or both as below



PARKING BRAKE SHOE ADJUSTMENT
1. Place parking brake lever in “full released” position.
2. Raise and support vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCEDURE)
3. Remove plug in parking brake shoe support to
access adjuster star-wheel (1).
NOTE: Through the access hole (2), rotate the
adjuster star wheel (1) in the following direction to
expand the shoes outward against the drum.
² Left brake – Rotate star-wheel toward rear of
vehicle.
² Right brake – Rotate star-wheel toward front of
vehicle.
4. Using an appropriate tool, turn adjuster star wheel
(1) until wheel will not rotate (dead lock).
5. Back off adjuster six detents (teeth).
6. Rotate wheel, checking for light drag. If drag is too
heavy, continue to back off adjuster one detent at a
time until light drag is present. Do not back off
star-wheel more than 17 detents from wheel lock.
LX BRAKES - BASE 5 - 171
7. Install access plug.
8. Adjust opposite wheel parking brake shoes using same method.
9. Lower vehicle.
10. Apply and release parking brake lever once to ensure proper operation of parking brakes




The emergency brake is intended to be used in case of hydraulic or mechanical failure
of the regular brakes......if by chance they become inoperable or compromised.

Alternatively, it can also be used to keep a vehicle motionless when it is parked.

The emergency brake, combined with downshifting of
the transmission......should be able to bring the car to a safe stop.

Poor performance of the emergency brake usually relates to lack of use.

As suggested.....an occasional light scuffing of the drum/shoes at low speed will help ( drive with it on, 100ft at 10mph).

But.....if you haven't used it for a long time.....then more than likely,
the shoe actuator lever is seized. It's a small two-piece component (1) that the cable
end (2) is attached to, which spreads the shoes when the brake is applied.....see image below.

Brilliantly made out of steel, it rusts into one lump and becomes useless, making the brakes
inoperable. It's easily removed and can be cleaned and freed up and then properly lubed.



It's always a good habit to apply the emergency brake occasionaly, both when parked and
also at low speed for a few feet. This will keep all the components in good condition

Thanks for the instructions - seems fairly straight forward.

Some questions:

- In the first set - where is the 'parking brake shoe support' located?
- Is there a diagram that goes with the first set of instructions?
- In step 4. it says 'using an appropriate tool', is this appropriate tool some sort of special tool or is it just a wrench, screwdriver, allen key or some other common tool?

Thanks.

its all behind the rear disc brake rotors, which have to come off first


try the other methods first,.....

  • repeatedly applying & releasing the pedal to its fullest extent to firm up the adjustment & reduce the travel
  • drive at 10mph for 100 yds with the brake on
if neither of those work, resort to the manual adjustment and/or check for seized parts & renovate with copper slip


sorry, my bad.... I believe the pics are in the service manual....heres the link, but its 172mb - http://www.lxforums.com/board/showthread.php?t=168376 ....however, its useful for everything else too, so its worth having!

I will give that a try. Thanks. Do you know what this 'appropriate' tool is that is needed to adjust? Don't want to get it all apart only to find out I don't have the tool to make the adjustment.

And driving for 100 yards with e-brake on, are we talking fully applied or just partially applied?

sorry, I cant tell you....I have the notion it was a flathead screwdriver, but I believe it varies....nothing too taxing though, specialist tool-wise

I have same situation on my 2017 Chrysler 300S. I replaced brake shoes, springs, adjusting levers, and adjusters, I put new rotors and my parking brake pedal go's to the floor. I try to adjust again, and go back four teeth, but my wheels go extremely hot and after a few miles they made a noise, as if I were riding on wooden wheels and parking brake still go's to the floor. What to do next? Replace parking brake cables?

You might get a better response by posting a new thread instead of trying to resurrect an eleven-year-old one.
