what does this note mean
i did today service b for my honda civic 2001 sedan, manual
transmission. the dealer wrote the following in the note ""all tires 7.5mm front pads 7mm (aftermrkt) rear shoes 4mm" what does that mean please? what does "aftermrkt" means (that how the spell it)? thanks a lot. |

Just a SWAG (Scientific, Wild-Assed Guess)but I think it means that your tires (all of them)have approximately 7.5 mm of remaining tread. Your front brake pads, not Honda OEM, have 7mm of wear left and, last but not least, you have 4mm remaining wear on the rear shoes. Aftermkt = After market parts which means nothing other than the parts are not made by Honda or labeled as such by one of their suppliers. |

As far as the brake numbers, you should ask them point blank what the service limits are so you can make an intelligent decision. I suspect there is no hurry there either. As far as the timing belt (build?), if the belt has never been changed, it is about due based on age. You didn't list your mileage, but 2001 Hondas generally specified the belt change interval at 7 years or 105,000 miles. |

He could, assuming there was any knowledge of how thick they were when new.

(the lining thickness...to state the obvious) Maybe find a sympathetic parts clerk that would allow him to measure a new set.[without having to actually buy them.... ;-) ] I would not use it as an absolute standard,but as a guideline or ballpark type of measurement. Of course,that -assumes- even pad wear for inner and outer pads.... It would be an interesting experiment. -- Jim Yanik jyanik at localnet dot com |

Yes,after figuring remaining mileage for total pad thickness remaining,you should subtract the minimum pad thickness(in miles) to determine how much usable mileage you have remaining. That minimum pad thickness is a safety reserve,to keep you from grinding the rotor with the backing plate,and causing a greater repair expense. -- Jim Yanik jyanik at localnet dot com |

Thanks,this is good to know. Heh,I was pretty close on my guesstimate of 10mm for a new pad. and that from memory! So,the OP's mechanic would have been "remiss" in not recommending new pads with his "7mm" measurement,as that would only leave 0.9mm "reserve" before the operator gouges his rotors.(if he included the backing plate in it) But 7mm of a 9mm pad would not even be worth mentioning to the customer IMO,plenty of pad life left. > > >> >> Yes,after figuring remaining mileage for total pad thickness >> remaining,you should subtract the minimum pad thickness(in miles) to >> determine how much usable mileage you have remaining. >> >> That minimum pad thickness is a safety reserve,to keep you from >> grinding the rotor with the backing plate,and causing a greater >> repair expense. >> > > > * - a "round" guesstimated number. > The two Haynes manuals(yes,but that's all I have...) I checked cited a 1/16"(.0625) reserve pad thickness,that works out to 1.6mm,so you would have 9.3mm usable pad thickness. However,in calculating "mileage per mm",all you need is original pad thickness and how much was left after the miles you drove,to get the amount of pad used per miles driven. What's left only matters in how close you want to gamble before installing new pads. Some people might choose to set a larger "reserve",in case uneven wear occurs due to a stuck caliper or other problem. That happened on my last brake job,I only had maybe 1mm left on the outside pad,and inside pad had hardly any wear.I had stuck caliper pins(Sentra) and had to buy a new bracket and pin kits,couldn't free one pin from the bracket. It's important to note (for the lurkers)that this calc only fits an individual driver and car,as people differ in their driving habits and use of their brakes. Some people like to ride their brakes,too... ;-( -- Jim Yanik jyanik at localnet dot com |
