| 484061 | 2006-09-12 07:23:00 | I am really surprized that NZ still uses black arts as mechanical rating systems for testing brake efficiency. i have to agree with joe here. those brake testing is known to be inaccurate. it was a topic of conversation not long ago with truck brakes as they no longer allow the old g meter type testing. |

| 484062 | 2006-09-12 07:38:00 | Back in the days of snakeoil salesmen and fly-by-night "technical" shops with their mysterious evaluations of things like brakes and muffler bearings, this is the same scare tactics garbage that was foisted on drivers . It is now illegal to perform these tests in California, if not in the whole federal US . Those numbers are useless and further, they are just ignorant witchcraft that went out with horse drawn cabriolets . Feel secure that brakes independently change their co-efficiency rates due to weather, temperatures and humidity, weight load on that particular side of the vehicle, tire pressure, tread depth, rubber hysterisis rates for unmatched tires off the same asembly line, if the tires have been rotationally rotated or not . . . etc . . . etc . I am really surprized that NZ still uses black arts as mechanical rating systems for testing brake efficiency . Nah, it is just a very quick test that your brakes vaguely work, so it can checked off as being "safe" . They aren't allowed to take anything apart to inspect things further . . . |

The figures quoted by lance4k wouldn't have come from a G meter but a roller brake machine. Rather more expensive than your average snake oil salesman would be prepared to invest. |

| 484064 | 2006-09-12 09:24:00 | exactly paulD, the roller testers have been known to be inaccurate and fail vehicles that have nothing wrong with them. the G-meter, while very basic properly dos a more reliable test. also the roller test sometimes gives them "cool looking data" to use to suck in people to do unnecessary repairs. just because they have fancy gear doesn't mean there aren't a bunch of *****s. i know several people who have bought vehicles with new warrants that actually have major faults with the vehicles (they where put off the road they where that bad). | tweak'e (69) | ||

Some roller testers could be faulty but my experience with 2 different VTNZ stations in Wellington is that the roller results do accurately identify unbalanced braking . I'd rather have something like that show up the problem before a wet road emergency stop goes sideways . The Oct 2000 VTNZ Newsletter mentions older hydraulic roller testers being converted to electronic control for improved reliability . |

| 484067 | 2006-09-12 20:45:00 | nz regulations were for brakes stomp on them and if the car stops in 10 meters from 50 km per hour with out diving left or right then the are ok. as for replacing disc pads it is a 5 minute job requiring a 12 mm socket and a G clamp to return the brake piston and change the pads. my aproach to any job is buy the bare tools and learn the job and come out cheaper than a tradesmans charge and have the tools for life. |

| 484068 | 2006-09-13 00:13:00 | Read this (www.racebrakes.co.nz) if you want to know all there is to know about brakes. I will be going there, when mine are needed to be changed. It maybe a bit more expensive, but when your life depends on good brakes (and good tyres and suspension), it would be a false economy to put bad brake pads into the car. |

| 484069 | 2006-09-13 01:00:00 | I think it's kinda dumb to suggest that changing brake pads is a two, or even five minute job for a beginner. Sure, it's straightforward, but not something that you want to muck up. Having said that, because it's so easy it's a good way to get your hands dirty and start learning that a lot of car maintenance and repair work is a heck of a lot cheaper doing it yourself. |
