In the same vein as Michael’s thread about the weather , but on a wholly different subject I thought I would ask for members thoughts about the MOT ( UK compulsery annual check of vehicle roadworthness ) Sorry this is not model engineering but it seems apppropriate for the tea room and perhaps of interest for many members.
Yesterday I took my 7 year old VW for its annual check, and it passed. The examiner recorded 2 “Advisory” comments.
1. The rear brake pads were 60 % worn. On the strength of this the girl on the front counter proposed to book the car in for new pads. I declined explaining that I drive only a few thousand miles a year, and that the pads were the originals so in 7 years I have worn away 60% of the pad. She was horrified when I suggested I thought I could get a few years more wear out of the pads as fitted. Apart from any cost considerations it seems wrong in this time of recycling etc to effectively throw something away when it still has nearly 40% of it’s life left. The girl seemed unable to distinguish between part worn pads and braking effectiveness. The front pads were recorded as 40% worn and the examiner made no comment about that.
2. The rear wheel springs were corroded. No percentage this time!. I reasoned that as the same examiner had not mentioned this at all last year the corrosion then must have been not visible or trivial, so it was unlikely to be particularly serious yet. I am getting too old to want to go about looking under cars, if the examiner thinks the car is good enough to pass, then that seems good enough for me. the cost of replacing the springs is eyewatering. Again the girl was not impressed, and this time there was no maths to assist my thinking.
So, I propose to ignore both advisories and look at the situation again next year.
What does the team think? Am I being properly careful with my money or reckless? Will a brake pad still be okay at 80% worn, or even 90% worn, where is the safe limit?
