Thread: Disco 3 handbrake screech

So I don't have the luxury of not using the EPB!


Thankfully I haven't had to manually release at this point.

I had a chance to do the clean and adjustment over the weekend with the guidance of Bodsy's brake bible.


I noted I need new rear discs and pads anyway, so I just hit the EPB with compressed air through the adjustment hole for now to blow the dust out of it and adjusted it. Was very dusty!
Judging by the amount of tension added and then released, my EPB system was quite out of spec.


So far so good - applied and released several times since then with no issues. All very quiet.

What brake is actually applied by the elec hand brake..?

Gyroman, inside the rear discs there are two pads on each side that are forced outward via cables by the electric motor when you activate the HB switch.

Same as an old fashion drum brake.

Search and download Bodsy's Brake Bible and it is not a hard task to inspect and service them properly DIY if you are reasonably handy. The setting up is key to long life and smooth operation and is not something I believe is well known outside the dealer or very good Indys. When mine first screeched and raised a fault I was initially told mine was kaput but I made them do another calibration (with me watching having pre-read BBB and like-magic it worked perfectly again. Now I do it myself.

I use mine enough just to keep it moving but avoid using it when I don't have to.

Oh, and don't drive off with handbrake on. Always release it at rest is the tip.

I was also told on steep hills to engage D (or R) to unload the brake before releasing (without moving off).
