I bought a new 1999 chevrolet suburban 1500lt in january 2000. within the first year, the brakes had to be replaced. i have endured this annual replacement of brakes ever since. six replacements have occurred and now we are looking at the 7th. the vehicle only has 75,000 miles. it is serviced at bredaman chevrolet in park ridge, il each time. each time they tell me nothing is wrong with the braking system although they have replaced it twice for free. *jb
