But his rear wheels were in the air.
What does it change?
When the wheels are off the ground you can feel the slack in the drive train.
With wheels on the ground you can't.

My 98 is similar in action, so that's why I am wondering if I have an issue... or if this is just the norm?!?

Ciao!

You are asking here if you have issues??

:D :D :D

My 1999 and 2005 both lock up with no rotation after I apply the hand-emergency-e-parking brake FWIW.

Bring it up to ALB and we will get you setup and Ill throw in a free NY inspection - they actually have to put the car up and remove a wheel here.
Almost be worth the trip just to say HI!!! You guys and your inspections..... :lol:

Thanks!! It'll probably be next week before I can dig into it, but at least I know I'm looking for something now!

Cheers!

Actually, more like $20.... VTL gave me that part on top of page 3, but you need this part too! https://www.fcpeuro.com/products/volvo- ... 0-30793438

Appreciate it though!!!

Would "sort of" make sense if the V70 is rear wheel drive, which it isn't, unless it's an XC70.

There shouldn't be much movement of either rear wheel at all with the parking brake engaged, wheels on ground or in the air, certainly nothing like what KS describes is happening.

That was my thought.... I'll grab a quick clip of it in action and quell any confusion in the gallery!!

There is end gap movement of the brake shoes until they contact the block (part of the steel knuckle itself) that keeps them from rotating,
that translates to movement out at the tire.

Jonesg... the keyword there being "gap"... what kind of gap is normal. A couple of thousandths... or a couple of tenths. That kind of difference can make for a wild ride!!

I used the transmission slop as a common example of car movement upon parking. I don't believe that parking brakes should allow a similar amount of movement and from the responses, my presumptions are correct. I would expect a little thunk, thunk from the shoes as they settle on the stops, but to get enough movement into then to sound like a dropped wrench seemed a bit excessive!

I'll open them up in a few days and see just what the heck is going on. I'll post up the findings so everyone that's chimed in can see if they won their bets!

Ciao!

I think the shoe end gap was about 1/8th inch, OEM vs aftermkt shoes had a slight difference in shoe backing length.

Dia of the wheel might make this a possibility. I'll let you know when I find out!!
