HR's have sucky handbrakes

I have got to say that I have had my handbrake on my HR fixed too many times and NOW it has failed me over the pits ONCE AGAIN! Grrrrrr I hate HR Handbrakes... They have got to be the worst thing ever designed unless mines just ancient and I have to replace it!!

In the 5 or so years I owned my HR wagon I must have changed the handbrake 3 or 4 times, in the 7 years I've owned both the sedans I've never changed the handbrake once...also worth noting is I rarely use the handbrake at all now anyway ;)

Yes though I agree, the HR handbrake system when used consistantly is absolutely hopeless, which is amazing considering how simple it all is.

It's all to do with the brake shoe arrangement inside the drum. I can't remember the technical name for it. Something like "double leading edge shoes" or something.

Anyway, the guts of it is that, the shoes are arranged in such a way that both leading edges (or toe) of the shoes is applied to the drum when the brakes are used. Older designs only had one shoe that was a leading edge shoe and the other was a trailing edge shoe. Leading edge shoes have a tendency to "pull" themselves on harder automatically, assisting brake effort, whereas trailing edge shoes do not.

Depending on the direction of wheel rotation, there was always one leading and one trailing edge shoe - they worked equally as well going both forwards or backwards.

By arranging the shoes to be double leading edge, they worked better, doing better braking, but only in one direction - forwards, which is how most people tend to do most of their driving at speed. The downside is that they don't work very well going backwards.

Your handbrake uses the same shoes, so facing downhill, the shoes tend to "pull" themselves on harder if there's any forward movement, but facing uphill, if the car starts to roll back, they don't work as well.

It's hard to explain without a diagram. I hope I haven't confused you more. Anyway, don't worry about it, it's quite normal for modern drum brakes. They all do it. They all work better going forwards than backwards.

Cheers

my HR handbrake works well(not as good as a new car, but it works) all you need to do is adjust it! and pull hard when you want it on ...

Hi Guys,
Ever consider that the HR handbrake assy is the same design as the FE.FC,FB,EK,EJ,EH,HD???
Well it is!
Why does it seem that only HR's have this problem??
In fact I've never driven a vehicle with this problem!
One of the main problems with handbrakes is 1. Lack of lubrication to: A: Handbrake lever assy, B: Pulley's and cables, C: Rests in the underbody and D; Rear cables rusted up due to No lubrication to the cable going to the rear wheels!
and 2. People do not know how to correctly adjust their brakes!

After stripping down down all of the pathing of the cables and generously coating eveything in Zinc Oxid grease ( The White grease!)
Adjust your brake shoes correctly as follows:
Undo the ajusting nuts to the Handbrake all the way OFF.
Then using the correct brake adjusting tool adjust the brake shoes so that the shoes are hard on, that is you can no longer turn the wheel with your hand, then back off the adjustment until you can again turn the wheel.
You should be able to turn the wheel fairly freely and hear the shoes scuffing on the drum but NOT binding too much on the drum.
Once this is done readjust the handbrake cable so that you get approx 80mm of travel when pulling on the handle from your knuckles to the handbrake anchore plate under the dash.

This should sort out the problem.
Cheers!
