So recently been knocked of bike, van reversed into me and I was stationary. Bent the right hand brake disc. Ik it's kind a dumb thing to do but didn't wanna go through insurance as they would have written the bike off and the cosmetic damage is just scratches so we settled that he pay me 400 quid and I'd buy the parts second hand or after market to get the bike road worthy again. For such a minor bump seemed to be a waste of time possibly having to wait weeks just to get bike sorted and that's if he admitted fault and didn't try claiming that I went into the back of him or something.
Anyway I managed to find mudguard from a bike breaker of eBay and from the same bike got pair of discs £160. The bike is 2002 model just under 20k miles on the clock so that's like 1100 odd miles a year. Thing has done less mileage than my bike and mines a 2005 model. Told bike mechanic at garage and he starts giving me sh*t for buying second hand as could be warped etc. Thing is they look in good condition from photos, no obvious scoring, advertised as in good condition so doubt they're warped, off a low millage bike and it's a bike breaker not some random person stripping his GSX down and selling parts without checking them first. It was that or buy Chinese discs and I really didn't wanna risk using Chinese disc breaks.
What's people's opinion on buying/using second hand disc brakes, am I stupid or is the bike mechanic getting on his high horse for no reason? Obviously replacing brake pads with new ones.
You pay your money and take your chance .
Make sure the bobbins are clean and if they are from a bike as discribed then happy days if not send them back and get your cash back .
I've fiited 2nd discs to bikes in the past without any problems from.low mileage donor bikes.
:cheers:
Just make sure both faces of the mounting point (disc & hub) are super clean when you put it back together. Little bit of crud in that area makes a big difference at the rotor's edge, leading to pulsing brakes & a diagnosis of warped disc, when in fact it's only a bit of crap in there.
Be careful & patient & should all be well.
I'd say the mechanic is pissed off with you because he wanted to buy the rotors & put his percentage on top. As Seth said, you take your chances buying anything second hand but hopefully the ones you bought are OK.
Yeah can't really see there being an issue except just less life span as they'd already be partly worn. Shall check the bobbins and clean them up if needed but highly doubt they're any worse than what my brake discs are like.
Ye I'd chance it.
Bought second discs for previous bikes and no issue .
Just check them over like has been said here.
And pay with PayPal,so if you have to return them your not stuck with the postage fee :onya:
The ones you had on there previously were used, so what's his problem?
Seriously, as long as they are within spec (which you can check with a micrometer in 5 minutes) and they aren't warped, all is good. And if they are warped you'll soon know about it. And if that happens, you can buy a new pair.
I'm not anti used parts.
If I had a spare pair of used but good discs sat on the shelf I wouldn't hesitate to put them on a bike, buying used from a stranger always brings other questions with it but the price should reflect that.
