The emergency brake is independent of the discs (there's a small drum system inside), so you don't need to worry about 2.

 

It was a 911 guy that told me many years ago to never put the parking brake on while the disks are hot. Is there anything different between the 911 and the 928 in this regard?

The concern would really only be warping the rotors when superheated. If p-brake is nowhere near the rotors....

Now you got me thinking that I should be using my parking brake instead of normal brakes while driving in the paddocks or when pitting.

I am guessing that the 911 guy was much smarter than me. I may have misunderstood and he may have meant that the parking brake should be used instead of sitting on hot brakes. I particpated at an AX course where the grid was on an incline - In this case, this practice would make a lot of sense. That was many years ago - my long term memory is probably not nearly as good as this guys advice.

Coming full circle, I think I have just re-learned something useful.

Thanks for jogging my memory.

 

Hey, no sweat!


You can see what they look like on Pirtle's page:

There's basically a drum brake that fits in under the rotor hub, it looks like.

That's the reason I use it everytime in the 928 - I know it doesn't screw up the discs, and it will keep it in working order for when I need it.

 

Nicole, that is precisely what I DO NOT want to do. I want the lights to work and I want the nose of the car to drop. Think about it awhile.

 

It seems that you WANT them to know that you know they are zapping you... ?

 

Remember I told you I had discovered a strategy?

 

I never use it, becouse on most of my cars it is broken. Why use it if you have a gear?

I only use it if parked on an incline. Takes the weight off the little parking bung in the tranny.

 

I use it all the time.
1. On a Saturday, when I roll it out of the garage, window down, key on and I give the car a little tug, keeps me from having to start it just to move it. I start it later and drive it after I clean up, after its cleaned up.
2. I wished it was a little more,,, grabby, or powerful, like my old 70 Buick GS with 11inch drums,,, then the 180's would be easier. The first time I tried it I was doing about 40,, I pull it and the cars starts to slow down. No lock up! means no 180's. I try again 40ish pull like mad and I just barley hear tires scuffing, Still not enough lock up,,,, so, No 180 time on dry pavement in my 928. Now wet weathers another question. Snow, what's that. Back up 180's? easy and only on my track tires.

Does anybody else's EBrake lock up the rears at say 40ish,, easy? I've had three that don't .

 

I always use it. If someone bumps you while parking it reinforces the parking pawl in the trans (auto) so it doesn't shear off.

I use it once or twice a month while I'm driving. Just to make sure that everything works.
If you drive the car daily it shouldn't matter if you use it. But I know from a friend with an old beetle that using the parking brake and not driving the car for 4 months, leads into a serious problem....

 

Always use it. By the way Abby - nice sig and love the name - Abby Normal - aren't we all

 

I don't know if it makes a difference on the 928 [or 911...], but they teach us to NOT set the parking brake on the 747 that I fly after a panic stop. This could cause the disks to literally weld to the pads!

Now of course, the 747 weighs upwards of 833,000 pounds on takeoff, and at that weight may need to reach 180 mph to leave the ground...so in the worse case scenario the brakes are expected to convert kinetic engergy to thermal energy some ungodly number [actually, I have a chart on my laptop that computes that, but I'm too lazy to pull it up- sorry!] that means you have to sit and let the wheels cool for an hour, and in the end you are likely to need a full brake job anyway. Not good, and the boss gets even hotter than the brakes~

The long and short is that the 928's parking brake is separate from the disc. The parking brake functions as a third brake system, and has no anti-skid function, since it is fully mechanical, as per certification requirements.

Anyone tried parking brake slides with this car? I've done plenty of donuts, but never this~

N!

 

I use mine when I am working on the car and when on a slope.

 

Hey has anyone replaced a parking brake assembly? Like I said my spring shot out of the handle and now she rolls when I am out at work.
