My, how strange it is that every time a modern car is designed the manufacturers feel compelled to re design the wheel !
Let me explain. BMW has announced the recall of over 350'000 vehicles due to what they term " A loss of vehicle power braking". What they mean is that the servo assistance to the cars braking is not working correctly and so the driver may well have to revert to "mechanical braking".
Servo's have been fitted to most makes of car for several decades, yet a system which simply involves a chamber with a vacuum present acting upon a piston which multiplies the force applied to the brakes when the driver applies them, has been found to be faulty. Surely this simple mechanism which works fine on every car i have ever owned during the last 23 years (23 vehicles in all) seems to have been "tweaked" by BMW to probably claim yet another innovation for the company!.
There is an old engineer's saying which goes "If it ain't broken, don't try to fix it". BMW and all other modern car manufacturers should take note of this mantra!.
P.S I have owned several Mk1 and Mk2 VW Polo's...they never even had servo's, and it didn't cause me any problems with driving them :-)
