Thread: Park brake screaming!

Well this is what happened - the technicians looked at the car yesterday and said that the the EPB was badly adjusted. So they re-adjusted it.
While doing that they noticed that the rear brake pads and discs were very low and needed to be replaced (I knew that from my previous service just 5 weeks ago and had planned to get the brakes done when we returned to PMQ in mid Jan). So I agreed to have the rear pads and discs replaced now as it would not last long - especially towing a 3 tonne van and another 2,000 kms. That was done and then off for a test drive and guess what happened! The EPB started screaming and would not release
So - a new module ordered and will be fitted today and thankfully under warranty which runs out in a few days

Sparingly, as in when you are on a steep hill. Mostly you are on near flat ground and pulling on the handbrake is just a reflex action.

If I can find some kerbing to rest on I won’t set it either.

It’s agreed not to rely on Park on steep hills.

Fortunately Perth is pretty flat.

Hope they 're-adjusted' it after replacing the rear discs also?

After that there is then a re-bedding process to be followed as per the brake bible.

Thankfully you are in warranty.

Yeah. I still think it would be their adjustment attempt but hey ho, it’s not your money so take the new one. Winner!

Just to put peoples minds at rest. My 2010 D4 has done over 200K, I use the park brake all the time and have had no issues with it. I have set it using my IID tool so it isn't automatic, I always release it manually before driving off. I do flush out the drums after I drive in mud and whenever I have the rear wheels off and I adjust it every 40-50K. It was getting a little noisy recently and I was overdue an adjustment. A flush out and adjustment and all is quiet again.

My previous 2005 D3 had 300K when I sold it, the park brake was still working but did like to flash when driven over corrugations.
