Re: [MBZ] Parking car in gear
The only time I've ever used the parking brake on a hillstop was my driving test... One foot on the brake, the other on the clutch. Release clutch until the engine starts to labor, release brake, quick dance to the throttle. In the case of a 240D MASH throttle to floor, continue releasing clutch -Curt Date: Mon, 26 Nov 2007 22:05:28 -0700 From: Craig McCluskey <[EMAIL PROTECTED]> Subject: Re: [MBZ] Parking car in gear To: Mercedes Discussion List Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=US-ASCII On Tue, 27 Nov 2007 09:27:35 +1030 Hendrik & Fay <[EMAIL PROTECTED]> wrote: > Hendrik > who likes the RHD 123 dash mounted hand brake and wonders how you do a > smooth hill start in a manual car with a foot operated park brake (eg. > the 124's) Make sure the foot operated brake is well set.

Re: [MBZ] Parking car in gear
There appears to still be a lot of confusion even to myself as to how the compression effect holds the car. I'm sure if you remove the spark plugs ( glow plugs for us guys ) the internal friction is not a significant contributor to keep the car stationary on a slope. If compression has an affect why after xxx no of secs/hrs/days does the vehicle not crank over to the next compression cycle? It means eventually no matter how new the engine is air will leak past the rings/valves. BTW does a diesel parked hold it better on a slope that a gasser?

Hendrik & Fay wrote: > > Auto boxes have a parking engagement device, however I STRONGLY > recommend that everyone get in the habit of using the hand brake, even > on flat ground. My employer at the Saab shop lost a parking pawl about 20 years ago. He left the car in the handicap spot closest to the store, flat parking lot, lever in 'P', handbrake off. A delivery truck backed into his car, no obvious bumper damage, but the Borg-Warner box didn't like it at all. Saab parking brakes in that era (Girling front disk parking/service brakes) could lock the front wheels with ease. If he'd set the brake, there's no way the tranny would have been damaged. As for the suggestion to leave the lever in neutral so that the lever wouldn't get stuck in 'P' if the parking brake didn't hold on a hill, would you rather return to your car to find tension on the parking pawl, or perhaps it's better to find your car not where you left it if the p-brake doesn't hold? The 'P' on the tranny is there for redundancy in case the p-brake fails. Using it *except* when on a hill where it might be useful is silly.

Re: [MBZ] Parking car in gear
Auto boxes have a parking engagement device, however I STRONGLY recommend that everyone get in the habit of using the hand brake, even on flat ground. My Mum had an experience recently whereby the car chased her because she didn't put the car in P properly and either she did not pull on the hand brake hard enough (easy to do on a RHD 201 because the hand brake is close to the passenger seat and you sort of have to lean over to pull it on hard) or did not use it at all. Luckily the car missed her by a couple of feet but it could have been very nasty. I recommend using P on autos all the time, engage hand brake and then place in P, if the hand brake is working properly the vehicles weight should not rest against the internal gearbox stop but that internal stop is a fail safe in case your hand brake lets go for whatever reason. There is absolutely no reason not to place the auto in P, they are designed to do this. It is things like this 'when on a hill/slope, e-brake and neutral with no park' stuff that makes me a great believer in making new drivers take professional lessons so they don't pick up bad habits from 'experienced' drivers. Pro driving instructors are best placed to teach the ins and outs of motoring.

Re: [MBZ] Parking car in gear
I've never understood parking in neutral. What if the ebrake fails? I've had several cars (mostly American) where the ebrake didn't work well at all... The ebrake in my 190D is acceptable but not terrific.

Re: [MBZ] Parking car in gear
That happens all the time here in the mountains. Four brakes engaged on iced parking lot might hold the vehicle but just the drive wheels in park, you shut the car door and the car slides away like a hockey puck. The owner's manual on the 300D gives emergency instructions on how to "jump start" the car if necessary by coasting it downgrade. This can be done with the automatic transmission in the Benz not just manual trans. 11/26/07 10:30 AM, Bill Ringgold at [EMAIL PROTECTED] wrote: > I saw something like that in Akron about 35 years ago on a sloped parking lot. > About 15 cars slid out of their spaces when the owners parked warm tires on an > iced lot.

Re: [MBZ] Parking car in gear
"I'll tell you: I don't know." - Tevye the milkman in Fiddler on the Roof. When one cylinder leaks down and the crankshaft turns, another comes up on the compression stroke. Or so it seems to me. The attempt to move the car with the transmission in any gear requires turning the engine faster than it might crank manually. In a lower gear, it really turns faster. This I think reduces the tendency of the car to move and self rotate the engine. Sometimes an old engine with weak compression will actually allow a car to move a bit, a herky jerky bit, especially in top gear.
