rolling resistance

[Cals911]

i bought my first porsche ever a 1986 911, one thing i have noticed is the car does not roll easily, noticed driving it home sitting at a light feels like the parking brake is slightly on, when i got home i gave it a push in the garage and it feel like something slightly dragging..or is it normal? calipars have slight drag? after a 60 mile drive no funky or burning smell....i am going to lift it up and turn each wheel to see if any feel different, anything i should check for? i do notice the parking brake only needs one click maybe two to be on.
thanks in advance
p.s i did'nt see a newbe thread

It should roll as freely as any car. Likely you have one or more brake calipers with stuck pistons. Jack up the car and try to spin the wheels by hand. If they don't spin freely, it's time for caliper rebuild or replace.

I recently adjusted my parking brake from way too many clicks to 4 clicks; could be the parking
brakes are too tight.

My guess is that it rolls as easily as half the air-cooled 911s out there. Most cars I've owned will sit in place with no brakes unless there is a clear grade to the street.

If your hubs and brakes aren't hot after a drive, I wouldn't worry too much about it. Maybe put 40psi in the tires and see if it changes things (not permanently).

The inner handbrake cable can partially seize in the outer sheath. I've had this happen on both sides in my 1978SC. It also means that it is pretty much impossible to adjust the handbrake properly.

If it’s difficult to determine by jacking it up and rolling the wheels then take it for a spirited drive for a few miles and get out and hit each wheel with a laser thermostat and find out which one(s) the hottest and there’s your culprit.
It should roll easily
Good luck

Good advice above on a few things to check. To check if you have a dragging caliper or e brake, there is an even simpler way. Take the car for a regular drive around town where you use the brakes regularly. After 10 minutes or so, carefully (in case they're hot) put your hand on each wheel. None of them should be terribly hot. The fronts will be a little warmer than the rears, left and right should be similar at each end. Look for the one that's hotter than on the other side. Or if they're all very hot after a casual drive, its possible they're all dragging.

Looks like it’s the left rear, I backed the parking off on that side, same, also all the tires had 15psi,
Probably going to order both rear calipers

Callipers are easy to rebuild yourself if you have the time and inclination. Seal kits are readily available and inexpensive

It could be the soft brake line hoses if they are original.

After doing a complete brake job on my 69E I thought I had fixed my non rolling problem. Well I was surprised to find I still had the problem. So I Changed the bearings in the trailing arms and now I can blow on the car and it will roll on it's own. And the brakes now stop the car very well. Just a thought.

I would remove the pads and try to retract the pistons. If they move easily you don't need new calipers.

Years ago my 72 started doing the same and it was the rubber brake lines. I switched them all and no problem since.
