Car Forum / Volvo Cars / July 2005'93 850, parking brake clunk?
'93 850, 5 speed, 143K miles. I get a nasty clunk from the parking brake when I pull up on the handle, when the car is moving forward maybe 5-10 MPH. As if something's loose inside the mechanism. Parking brake mechanism also seems balky, sticks sometimes. I'd like to pull off the hub nuts on both sides and remove the brake rotor so I can inspect the parking brake assembly. Anyone know the size socket required for that large hub nut (under the removable hub cover)? Looks to be a 35mm or 36mm socket, (more than 1-3/8", less than 1-1/2"). I have a long 1/2" drive breaker-bar, if I can get a 1/2" drive socket big enough I should be able to back-off that hub nut. It also appears to be either a locknut with a nylon insert, or it has loctite on the threads (can see something blue between the threads where they meet the nut). Has anyone done this? Thanks, Mike > I get a nasty clunk from the parking brake when I pull up on the handle, > when the car is moving forward maybe 5-10 MPH. It does it at highway speeds also. This is normal. They did it when the were new and still do. It only happens once until you drive a while, then you can make it do it again. The parking brake is a drum brake. The shoes must be quite a distance from the drum but take a while to get back.  SignatureCheers, Steve Henning in Reading, PA, USA Owned '67,'68,'71,'74,'79,'81,'87,'93,'95 & '01 Volvos.

SignatureMike F. Thornhill (near Toronto), Ont. Replace tt with t (twice!) and remove parentheses to email me directly. (But I check the newsgroup more often than this email address.) Thanks for that tip on Volvospeed. I had actually read that before, but missed the mention of the 10mm pin, which has to be removed, it looks like, in order to get the rotor off. Is that pin removable on the '93 850? The picture shows a 5-lug Cross Country rotor. I have a 4-lug 850 rotor. I assume the pin comes off with a 10mm socket? Will be nice not to have to pull that large nut off.

There is a picture there of the FWD type rear rotor, on the first page. That center cap you see in the bottom 2 pictures does not need to be removed. SignatureMike F. Thornhill (near Toronto), Ont. Replace tt with t (twice!) and remove parentheses to email me directly. (But I check the newsgroup more often than this email address.) Mike F, thanks. AH, yes, I see from those pix that the hub cover is still there. Before reading all this, I did pop it off, thinking I had to back off the big nut. Luckily, I don't. AND luckily it's on so tight that I didn't back it off. That probably would not have been much fun. Regards, Mike >> Thanks for that tip on Volvospeed.

There is also a small amount of - presumably intentional - rotational movement of the shoes inside the drums. If you come to rest on a slight slope, using the footbrake, and then apply the handbrake, the car rolls an inch or two down the slope. It's a bit disconcerting at first, but once you get used to it, it's not a problem. Anyway, the parking brake is for . . .er . . .Parking - so you should only apply it when the car is stationary - then you won't get any nasty clunks. You have perfectly good disc brakes to stop you from any speed above zero. SignatureCheers, Bonnet Lock ______ Please reply to newsgroup. Reply address is invalid. Had a similar clunking on my 1995 850, and was particularly bad when backing up from a cold "overnight" sit in the garage. Found that rear parking brake shoes had disintegrated!! and broken pieces of the shoe friction material were jamming between the metal shoes and the drum. Replaced parking shoes, spring kits etc. and all was fine. > In an earlier contribution to this discussion, > [quoted text clipped - 17 lines] > apply it when the car is stationary - then you won't get any nasty clunks. > You have perfectly good disc brakes to stop you from any speed above zero. > Had a similar clunking on my 1995 850, and was particularly bad when backing > up from a cold "overnight" sit in the garage.

The clunk when the car is moving and you put on the brake happens on new Volvos, at least the full sized ones with drum parking brakes, fresh out of the factory. (I don't know if the 40/50 Volvos have drum parking brakes) It is something that few people experience since they don't put on the parking brake when the car is moving. I like to use my parking brake when I am in traffic that is just creeping. I will shut off the engine and coast using just the parking brake if possible. It only clunks the first time unless you wait a while and drive over bumps and stuff so the slack that causes the clunk comes back.
