Title: Lurching with handbrake.
Post by: constipated on December 23, 2011, 11:11:18
My i30 manual since new has had a lurch whenever the handbrake is applied on a slope.

I've been used to this sometimes in automatic cars with loose handbrakes which rely a bit more on the P setting of the transmission to hold the car.

My handbrake does not seem loose as it will hold the car on a hill without any issue, it just seems like there is a delay in it biting causing the car to always lurch backwards or forwards on a slope, though not by much. This is disconcerting because I've never experienced this in a manual car.

Usually in a manual car, because the importance of the handbrake in hill starts I've always expected it to bite and hold from the minute it is applied.

Has anyone else noticed this?

I think I have the same issue with my car.
Some times it feels like the car moves a bit after applying the handbrake, even when the car is stopped 100 % by footbrake. I also find that unusual. So far I have thought I was imagining things, but is somehow glad to know it is not just my car  :D

Common as muck... same thing happens with mine. It's no real biggy tho - we've got a couple of threads on here raised over the years.

Might this be related to the fully independent rear sussies?

sussies..??? is that short for suspension..?

If thats what you mean, than I think not. My other car, 1993 Nissan Primera have independent suspension also, but the handbrake dont have this issue.

The handbrake and the standard headlights are the two weakest design points on my diesel.

The handbrake never really feels trustworthy, allowing wheels to slip on a slope...something I have earmarked for inspection if Hyundai ever see my car again for servicing.

My Subarus both did it.
I've found it more prevalent on cars with rear disc brakes than those with drums.

The Hybrid does the same thing (but it is CVT transmission)

Trish seems to think her CW does too.. I've found the i30 handbrakes to be effective...

I suspect Daz was more into the "Munsters" than "The Adams Family" if that response was anything to go by.... :lol:

Has anyone else noticed this?

I've also been used to driving automatics, an XJS (apply and push back down as it is by the door) and a 2.5l v6 Ford Mondeo.  Compared to the Mondeo I have been very impressed with the handbrake on the i30 as it only needs a small amount to effort to hold the car.  As you probably know the handbrake is also known as "The Emergancy Brake".
I test the "Emergency Brake" on every new car I own to see how well the car will stop if ever the foot brake fails.  The heavy Mondeo would stop at dual carriage way speeds obviously at at an extended distance when compared to using the peddle without any locked up.  The i30 handbrake doesn't seem to apply  equal pressure to both wheels, this caused the RH tire to lock up. 

Not noticed any delay but I wonder if this is the problem, one side is coming on before the other due to a bit of slack in the cable on that side??

My car had only done 800 Miles when i tried this so the pads might not have fully bedded in, but I wasn't going fast.

If your handbrake doesn't lock the wheels at the same time, there can be  reasosns.

1. Different surfaces under left/right wheel.
2. Wrong adjustment of the handbrake.
