One problem related to brake differential proportional valve has been reported for the 1997 Chevrolet Tahoe. The most recently reported issues are listed below.
My Tahoe has warped the front rotors under normal use(no towing) under warranty 6 times and twice more out of warranty with only 38k miles total. Cheverolt dealer claims there are no technical bullitens on this problem even though I've learned the suburban has a similar issue requiring a proportioning valve replacement. On average this Tahoe has warped the front rotors every 4000 miles. What can be done to resolve this issue?.
