Query About The Brakes In My Swift Dzire Ldi

Hi,

 

I've had problems with the brakes in my swift Dzire Ldi.  I have complained to Mandovi and Maruti on 2 occasions. There is a new brake cylinder which is fitted in post april 2010 swifts, and the braking distance is now much reduced, but they are not willing to fit it, saying that my car brakes are perfect. I usually drive on the highways, and early mornings at good speed av. 120 kmph. So they tested my car, at speed of 100-110kmph the braking distance was 67 metres acc to them. Is that normal braking distance? what should i do? The new brake booster cylinder assembly costs 4k including labour, but my car is in warranty and I'm claiming for it. Don't use the Dzire nowadays, its parked in my garage at bangalore. Should i go for the new brake cylinder or just lodge another protest?

Please help. 

 

I didn't find the right solution from the Internet.
