XC70 Electric Handbrake
Hi,
I posted this query at the end of a thread about EPB's but I think my question may have got lost at the end of a lot of replies.... My question is related to EPB's but different.... I have a 2009 XC70 2.5D AWD. When in "Park" the EPB automatically comes on. So far so good - but I often leave the car for longish periods (weeks not months) and, on occasion, the EPB has been sluggish to release. I suspect this is because the pads have stuck to the discs. My previous car was a Jaguar and it had a feature where you could hold the EPB switch down as you switched off the ignition and the brake did not engage... Is there a feature like this on a Volvo?? I have tried to find out via the handbook and online , No luck so far! Does anybody know if this feature is available?? |

By the time my 2012 XC70 came along, this automatically applied EPB feature seems not to have been offered. However, Technical Notes for Volvo Mechanics does mention that some XC70s have automatic EPB but doesn't specify which ones. The UK 2009 handbook doesn't mention it. Nor does the US handbook for the same year. Does your car have "Hill Holder" automatic EPB braking? I suspect that automatic EPB and Hill Holder will have been complimentary systems. My car has neither even though it is a hi spec model so this seems to be a somewhat random feature.

Hill hold is for manual gearbox cars only, as far as I know.
None of our XC70's have automatic parking brake either. Only automatic release on takeoff. |

Ah - Interesting that it seems random and this may explain why I can see nothing about it in the handbook.
I don't believe it has "Hill Hold" but it may be that I've just never needed/noticed/used this feature. I am however certain that it automatically applies EPB in P for Park. |

The only reason I can think of that this becomes an issue is if you disengage the handbrake (EPB) before you set off?
EPB is meant to automatically release when you start to apply drive/torque. If it's sticky through oxidisation the rotational forces soon cause it to release. If you disengage a sticky EPB first then it may well stay a while as you're only asking it to "free" in one dimension (away from surface) and not two (away from surface and rotational perpendicular to surface). Just my thoughts and a question. I live in a damp/misty part of Wales and this does happen sometimes but more of an issue with my RRS where it has separate shoes.

I have an '09 XC70 D5 AWD with an EPB and although it works fine every time I've used it I confess to being a little nervous about it releasing, no problems so far however.
It doesn't take much to imagine being in a queue of traffic with a stuck parking brake. I use the EPB only when really necessary, like on hills for a protracted time, otherwise it's into neutral or very occasionally P. Parking up is fine I think as long as the car is released very gently in the Park position and the hill isn't very steep. Are we saying that if the brake sticks that it will free off if driven against? |
