Hi i was just washing my car and noticed the back brake discs are SLIGHTLY rusty looking, My neighbour has a 55 plate bmw and he is on 3rd one that i know of and ge says that it happens quite alot to all his bmw that he has had in the past........This is what he told me to do
But mate thinks no. As it could warp the discs
Spray wb40 go for a drive and 4 or 5 times over a 5 mins drive apply the handbrake slowly and then release while driving....
Anyone else beleif in this... Done want to do it only when the pads and discs are all new only 6 momths old
