news the garage I use now at full price failed me for indicators bulbs not coloured enough so the replaced the bulbs and then passed it at no extra charge...now there is a garage you can trust ..... Mine tends to pass the car on the assumption that the lights are working, and then replaces any bulbs to make that happen - so as not to record a fail and then a pass-after-rectification. I usually check bulbs before taking the car to be tested, because I once had a garage fail me and then charge a retest fee. I presume a garage makes a bit of money on that, so it's good to find a garage which doesn't take advantage. It's in their best interest because I never went back to the garage that ripped me off so they lost all my future MOT and service custom. I'm trying to remember the last time any of my cars failed an MOT (apart from the technicality of a duff bulb from the rip-off garage) because all other garages have not recorded a fail and then a pass even for things like brake pads they've had to replace or headlamp alignment that needed adjusting. When you find a garage that plays fair, you keep going back to them. |

I've only had that happen once on a car: I was going down a long steep hill and suddenly there was a grinding noise. I wasn't aware of any loss of braking force, presumably because the other brakes took more braking force if the worn one stopped braking as effectively. I've never ever seen a disc pad with the lining riveted. Even in the 1960s. Ok, well whatever was worn caused the pads to score the discs when they were applied. I assumed that rivets were revealed when the lining wore down, but evidently I'm wrong with how the scoring was caused. Discs get scored by road grit, etc. Doesn't effect their performance. -- *It doesn't take a genius to spot a goat in a flock of sheep * Dave Plowman London SW To e-mail, change noise into sound. |

And changing gear purely to slow the car does cause unnecessary wear on the box and clutch. And uses more fuel and causes more pollution. Not true. You can change gear and not do any extra wear on the clutch or gearbox if you do it properly. The engine does the braking and it will be running anyway. It won't be using any fuel while slowing so where does the extra pollution come from? Either you increase the engine speed as you change down thus wasting petrol or you let the clutch speed up the engine wearing it more than needed. And not all cars cut off the fuelling totally on the over-run. -- *Nostalgia isn't what is used to be. Dave Plowman London SW To e-mail, change noise into sound. |

... Either you increase the engine speed as you change down thus wasting petrol or you let the clutch speed up the engine wearing it more than needed. And not all cars cut off the fuelling totally on the over-run. For cars that don't cut off the fuel totally on overrun (I thought all cars with fuel injection did cut off) is the amount of fuel used dependent on overrun revs? In other words, will they use more fuel in a lower gear (changing down to give engine braking) than a higher gear (staying in top until you're ready to set off). And is it more or less efficient to brake in gear or to press the clutch? My car uses *some* fuel (instantaneous mpg shows as about 250) if I press the clutch and let the engine idle, but uses *no* fuel (mpg shows as 999) if I stay in gear and let the car slow down on overrrun. I wonder how much fuel is used in accelerating the engine to match a lower gear before going down a long hill? Is it a measureable amount? |

"NY" wrote in message o.uk... "dennis@home" wrote in message b.com... The biggest problem is if the pads wear down to the rivets that fasten them to the backing plates, because the rivets can there score the discs, I haven't seen pads with rivets for years. I believe it has been law for many years that cars have a warning system to show worn pads. Its used to be a copper stud set into the pad connected to a wire that shorts to the disk and lights a lamp. Mine is indicated by the computer but I expect its still a copper stud. The biggest failure mode is the wire falling off the pad. Could it be the copper stud embedded in the pad that causes the scoring of the disc in the same way that (in the olden days) rivets would do. I checked the warning light when I experienced the symptom, knowing about brake pad warning wires/studs, and the light (the same one as used for handbrake-on) did not light, so it may be that the wire had fallen off since the last time the brakes have been checked and passed for another X thousand miles. I'm intrigued that a lot of people have done large mileages without needing new discs, I'm not, because I know its because I dont use the brakes that much. because on all the cars that I have had, brake discs tend to be needed roughly every three times that the pads need changing. But when you only change the pads once in 45 years, its hardly surprising that the discs are still fine. And that's with fairly gentle progressive braking (ie not rushing up to lights at 60 and then slamming hard on at the last moment). I dont normally slow the car at the lights with brakes. I do usually apply the brakes just at the end so the car doesnt drift forwards or backwards while waiting for the lights to change, but that obviously doesnt wear the brake pads any. I presume it makes a difference if you live in hilly country: Not with me. I hardly ever use the brakes in hilly country except when actually pulling to a stop before applying the handbrake after I have stopped. even with engine braking to take some of the braking load, you will still use your brakes more than if you live in flat terrain. I dont. Mind you, modern learners are taught not to use engine braking on a long hill, but to stay in a fairly high gear and rely entirely on brakes - that's what my nephew said he was told, anyway. I do very little engine braking in the sense of changing down a gear in hilly country. I wouldn't like to descend Porlock Hill, Rosedale Chimney or Park Rash using only my brakes, without going down into maybe third or second to give at least *some* engine braking. Sure, but there arent to many that do a hill like that daily or weekly. |

I went over to Bangor on the A5 a few years back, in a Cavalier SRi, with the uprated brakes. Shortly afterwards I noticed a vibration under braking... when it happened again after I went back I decided to use the engine a bit more over the Welsh mountains. Brakes aren't _that_ much better than they were then. Depends on what you mean by 'then'. Try comparing the brakes on an old Jaguar with drum brakes against a modern one in a panic stop from top speed. -- *A bartender is just a pharmacist with a limited inventory.

I havent needed a set of pads in 10 years and only needed one set of pads in the previous 45 years with the previous car. sounds about right for a Crosley. The 45 years was a Golf. The VW Golf was launched in 1974. OK, so only 43. Anyone ever suggested to you that if your hoover dies, all you need to do is take your pants off and scoot around on the floor on your bare arse ? |

The biggest problem is if the pads wear down to the rivets that fasten them to the backing plates, because the rivets can there score the discs, which when new discs are usually necessary even if the old discs still have plenty of thickness. I've only had that happen once on a car: I was going down a long steep hill and suddenly there was a grinding noise. I wasn't aware of any loss of braking force, presumably because the other brakes took more braking force if the worn one stopped braking as effectively. I had a pad on my Renault 20 wear down to the backing, which made for a gentle run home. There was a monitoring wire which fed an indicator, but because it was on the easiest side to run the wire, it was also on the side of the caliper which wore least. :-( Chris -- Chris J Dixon Nottingham UK Plant amazing Acers. |

And that's with fairly gentle progressive braking (ie not rushing up to lights at 60 and then slamming hard on at the last moment). Those who claim vast brake life must drive very slowly on quiet flat roads. Maybe they can drive? You don't use your brakes much on a motorway. Is that somewhere else you hardly ever go? I suppose not, I have only driven about 1.6 million miles on motorways. Th way you keep contradicting what i say I can only assume you can't drive and are an foot on accelerator foot on brake idiot. |
