Depends on what state they are, the garage that did the porker failed it on brakes as well as all the rear lights being "inneffective" meaning they worked but were not bright enough. They were basically angling for me to pay for all the bulbs to be changed as: "they go black over time mate"
Bollocks. I took them out and clened the reflectors, back to just dim instead of feeble. Fair cop on my brakes being duff, factory wear limit was somewhat greater than the thickness of my disks... About 50% greater...
I treat all garage opinions with suspicion, check them out, measure it all and see how it adds up. Rossybee can vouch for how long pads last, the last 3 mm or so lasts for ages... (The backing plate!)
