Not sure I agree with that davo, you would have to clean all the road crud off the pistons before shoving them back thru the seals, and I have always relied on the flow of fluid to carry the old stuff out the bleed nipple . I can see the theory behind such a move but I have never heard of it before. It can become a big job because logic suggests that .......if you change the m/cyl you should change the fluid , so maybe should clean out the calipers and if you do that you will need new caliper seals ......may as well replace old hoses and pads too then , and you wind up reconditioning the whole system ....then theres the back brakes .....and the clutch.....which can be a proper bastard to bleed. Dont get me wrong , its all good stuff to do , something a lot of peeps overlook .
My car has abs and stability control, the plan was to change ALL the fluid but when I saw all the pipes and hoses ,mysterious looking slabs of steel bristling with said pipes and hoses and electric motor .......I took it to the dealer .
