Hi john and allen thanks for the advice about the discs,calipers and pads any way cut a long story short i took the car to my mechanic to give it a full service and take the wheels off to look at the brakes. The car has done 135000 not had a service for 2 years when i looked at the service history log book, The car had one owner from new the car is very clean in side and out any way my mechanic rang me today and said the car is ready i said to him how much is the cost of the job he said £120 i was shocked i said no parts he said no theres nothing wrong with brakes discs,calipers and pads ok still in shock paid him the money and drove the car out onto the road to go home the car drives like a dream its running and stopping better than when i took it in to the mechcanic it used to sound like a tractor engine now i cant hear the engine its like my mechcanic waved a magic wand i am still in shock money well spent car drives like new and stops like it should do . Great bit of advice fellow members i love my lexus 220d and the girls love too.
