Brakes have improved - engines have become much more expensive to maintain whereas brakes haven't and have improved no end in capability so the logic is quite apparant, use the brakes - cheaper and considerably more efficient. I've never seen the point in going down through the gears, its easy enough to go into gear if accceleration is needed. The one exception is/was snowy/icy roads, where engine braking reduces the tendency to skid, plus a rear wheel skid has a lot less impact on control than a 4 wheel skid. However with ABS now that's the other way round too, leaving the only real use for engine braking being as a last resort for brake failure. Which rarely happens on modern cars anyway. And few people drive leaving enough space for brake failure any more. NT |

With old fashioned drum brakes, there was a tendence for them to 'fade' if they got too hot. This happened if you were using them for an extended peroid. The other reason for slowing the car with the aid of the gears is that if you have to accelerate suddenly, you will be in the correct gear to do so. Slowing with the gears, used to be known as "engine braking". I understand that if you change down a gear in a large Volvo when it is going somewhat over the speed limit, you do indeed cause "engine breaking". -- From KT24 Using a RISC OS computer running v5.16 |

I tempted to say that is their problem but having nearly being caught by a car with no working brakes lights... They where stopping to fast to be on pure engine braking. With old fashioned drum brakes, there was a tendence for them to 'fade' if they got too hot. You've not managed to fade a set of ventilated disc brakes then? Your not trying hard enough. B-) I've done it and it's rather disconcerting, the really hard bit is then nursing them once some braking has come back so they don't fade on you again. This happened if you were using them for an extended peroid. My occasion was towards the bottom of a "sprited" decent down from Hartside to Melmerby, about 1500' in 5 miles with fast straight sections and sharp bends. But yes people these days do seem to use the brakes in preference to the engine. I guess this isn't too bad pootling aroud town but not so good on long down hills. I don't think I've ever seen a car go down Causey Hill in Hexham just on engine braking. It's a 30 limit and not all that long or steep but everyone goes down on their brakes. Me? 3rd gear no throttle and it just potters down without gaining or losing any speed or wearing the brakes out. -- Cheers Dave. |

Seems the modern driving technique only allows you to do one thing at a time, I use the brakes and gears to slow down. On snow it'll be far more engine braking, no chance of locking the wheels, still might slide but you are in gear with still driven (aka revolving) wheels so you have a much better chance of regaining control or have some control. -- Cheers Dave. |

The bit I think is silly is when eg people approach a roundabout where they can see they're going to have to stop, but still go 5th-4th-3rd-2nd-1st, rather than 5th, brake, clutch in, 1st before it's time to go again. Substitute the appropriate gear for the speed required after the slowing down part for different situations. |

ISTR dipping the clutch whilst using the brakes (not obviously when coming to a stop) was a fail in the driving test. Using the gears to assist (not replace brakes) leaves one in better control of the car. The automatic gearbox in my 7 series can be felt changing down as the speed reduces under braking.

They still appear to work when glowing red, so too hot will probably result in warped disks rather than fading. Of course there are some pretty cr@p pads out there (fakes, etc.) that will fade, decent ones are a lot better. |

Talking of snow quick fit have 25% off winter tyres ATM. ABS requires a level of rediual grip for the system to detect that the wheels are starting to slip or are locked up but still gripping the surface. If lock up your wheels in snow and ice then ABS is about as much use as a proverbial. It assumes that you have stopped as there is no feedback from the wheels to suggest anything else. I must disagree with your wish to lock wheels up in the snow - this just sets you off down the road like a sledge, especially down hill with a steep camber. I have had a few scary moments with powerful automatics and ABS. In gear, the tickover pushes you forward at a considerable speed and if you brake then everything locks up and you slide. The only way out I have found is to put the auto box into neutral and then use the brakes. In a manual car you have much more control as you can dip and slip the clutch to adjust the amount of engine braking at the wheels. Cheers Dave R -- No plan survives contact with the enemy.

Substitute the appropriate gear for the speed required after the slowing down part for different situations. That's because they aren't very good at driving and can't select the correct gear quickly if circumstances change so they need to select the gears as they go. |

For slowing I just take my foot of the accelerator (or release cruise control). Brakes are a last resort if you are going too fast! the brake pedal is a switch for those rear lights, no need to press it hard enough to activate the servo most of the time. Having said that I had to stand on the pedal last night when some halfwit pulled out across me. I nearly had the rear end remodelled as the bloke behind ended up halfway alongside me.

I think we need to have an input from a member of the generation who learnt to drive when brakes were really something you used in emergency only as they were in general something that one day was reliable and the next day not. 1920s? Not many cars like that still on the road. My first vehicle (elderly in 1960) had brakes that were operated by cables - I did a major rebuild on it and had to tune up the brakes to pass the recently introduced MOT. The day following the successfully passed MOT, the brakes were in all reality pretty useless, so yes you had to use the engine as a brake and double declutching down a hill was a skilful task. Brakes have improved - engines have become much more expensive to maintain whereas brakes haven't and have improved no end in capability so the logic is quite apparant, use the brakes - cheaper and considerably more efficient. I've never seen the point in going down through the gears, its easy enough to go into gear if accceleration is needed. it takes at least half a second though. I guess u never drove 'enthusiastically' The one exception is/was snowy/icy roads, where engine braking reduces the tendency to skid, plus a rear wheel skid has a lot less impact on control than a 4 wheel skid. ...and were heavy handed on the brakes. However with ABS now that's the other way round too, leaving the only real use for engine braking being as a last resort for brake failure. Which rarely happens on modern cars anyway. And few people drive leaving enough space for brake failure any more. NT |

Google tells me :- "Gears are for going and the brakes are for slowing". Seems to be the thing these days. Crazy :-( I've always used gears for slowing and always will - seems much safer to me. Why do you think gears are safer? Brakes act on all four wheels and the brake lights warn the driver behind, who may be too close and/or not paying attention. With old fashioned drum brakes, there was a tendence for them to 'fade' if they got too hot. This happened if you were using them for an extended peroid. The other reason for slowing the car with the aid of the gears is that if you have to accelerate suddenly, you will be in the correct gear to do so. happens with disks too. just not so much. Slowing with the gears, used to be known as "engine braking". I understand that if you change down a gear in a large Volvo when it is going somewhat over the speed limit, you do indeed cause "engine breaking". |

I believe the same is true of disc brakes, though perhaps it's a bit more difficult to get them "too hot". Disks will glow red if you use your brakes a lot. They still appear to work when glowing red, so too hot will probably result in warped disks rather than fading. wrong. Of course there are some pretty cr@p pads out there (fakes, etc.) that will fade, decent ones are a lot better. |

Modern cars have ABS to stop you locking the wheels. Not that you want ABS on when driving on snow as you want to lock the wheels if you have to brake. Talking of snow quick fit have 25% off winter tyres ATM. ABS requires a level of rediual grip for the system to detect that the wheels are starting to slip or are locked up but still gripping the surface. If lock up your wheels in snow and ice then ABS is about as much use as a proverbial. It assumes that you have stopped as there is no feedback from the wheels to suggest anything else. Modern ABS may well be more sophisticated but back in the 80s my first ABS equipped car ran away down a steep snowy hill with next to no retardation. OK so I could still steer but what good was that when the gap between the rubbernecker parked at the bottom and the van coming the other way was less than the width of my car. I must disagree with your wish to lock wheels up in the snow - this just sets you off down the road like a sledge, especially down hill with a steep camber. If you are sliding downhill in snow it is only the build-up of snow in front of the wheels that gives you a chance of stopping. -- Roger Chapman |

I've got drums on all four wheels on the ('60s) truck, and no servo- assist. Stopping it can be a little interesting at the best of times. Engine braking is a bit more tricky too because it's a column-shift, so it takes a little while to swap between gears (and there are only three of them, and forget trying to put it into 1st above a couple of mph anyway :-) Never had anything with cable brakes, though. Most of my cars have been '70s and at least had floor-shifters and discs on the front - even then braking performance without using the engine in tandem with the wheel brakes wasn't exactly impressive. Brakes have improved - engines have become much more expensive to maintain whereas brakes haven't and have improved no end in capability so the logic is quite apparant, use the brakes - cheaper and considerably more efficient. TBH I'd expect to get 200,000mi out of a clutch these days, engine braking or not. At that sort of mileage I'm not too worried about it, as it's getting into the sort of territory where I'd start expecting other component failures anyway. OTOH, I %$^*ing hate changing brake pads, I really do - of all car maintainance jobs it's always the one that never seems to go as smoothly as I think it should! cheers Jules |
