Good point.As others say. If your only pootling along at 50 mph, do you need vented. My 1985 110 old discs and pads were shot so I changed for new stock standard discs and pads ÂŁ40 all in, and they stopped the 2 tonne old girl on a sixpence so to speak. When I had her mot'd I'm sure it was pulling something like 400 lbs at the front on the rolling road brake meter.
Maybe they changed the brakes after updating the engine that could 'comfortably' do 70 mph.
But its not, if you are rebuilding the brakes anyway.its a lot of faff and money for very little gain,
Did you find a solution to this..?Ive fitted front vented discs and pads to front of my defender 90 1985 and new stubs and cv joints,but now the drive phlange end wont meet up with hub by about 5mm,any ideas
