Ferrari Mailing List: Re: 308 Emergency Brake Adjustment

[Peter Rychel (dino308gt4]

What about the proper bolts? Do you have the entire car up in the air, on four jack stands, with all of the wheels off? I believe the wheel bolts for the front wheels are longer than the rears, so, if you’ve rotated your wheels during this service (I do), you may have accidentally used the wrong, longer wheel bolts in the back. This is the only thing that comes to mind when you mention totally locking up the rear axle once you put your wheels on.

 

You adjusting the rear brakes reminds me to do this with my car during the next service. If you haven’t already, get the aftermarket stainless screws for the calipers from the Porsche supplier, Automotion (if they still carry them). Way better than the original screws which always tended to seize up.

rjlloyd on f-chat had a good idea that I'll try on my next attempt. I'll keep the wheel off, tighten the lug bolts on even though the wheel isn't on, then check/adjust clearance.

I just posted this on f-chat, but I'm posting it here too to see which forum has a good answer first (competition between f-chat and f-list!). I'll post it on Facebook and see if someone has an idea there first.

Frustrated....

Ok, so I've done this job before, and I've done several cam belt services including valve adjustments, so the fact that I'm not having success here is making me very irritable, so I'll vent here in hopes someone can help.

Issue was that the e-brake did next to nothing, and I was replacing tires/doing an oil change, so why not do the adjustment. I have adjusted all four caliper hex thingies such that there is 0.1mm between the pad and the calipers. I've double checked. We're all good.

To reduce confusion, I've completely disconnected the e-brake cable from both calipers.

Now my rear wheels won't turn at all. I have the rear wheels up in the air (jack stands), I put it in reverse, and the wheels do not turn.

Wait, that's not exactly true. If I back off the lug bolts just a tiny bit, one at a time, on the fifth and final loosen, the wheel turns fine. If I have no wheel on and I put the car in neutral, I can turn the wheel disk by hand. But if I put the wheel back on and tighten it (not even to the normal torque setting), I can't even turn the wheel in neutral....until I back off the bolts.

What am I doing wrong? Yes, I have the rear tires in the proper size on the proper wheels.

Thanks for any assistance!
