Two problems related to brake foundation components have been reported for the 1998 GMC Yukon. The most recently reported issues are listed below.
Brake system on the Yukon is a weak link on an otherwise great vehicle. We have complained about the brakes to the dealership numerous times and was told that it is normal. The problem with it is that the pedal goes almost to the floor everytime it is used and you tend to wonder if the truck will stop in time. I read in the paper this week that the Yukon's brakes on the 1999 and later trucks were recalled and would bet that the problem is the same. Either way I want a complaint listed about these lousy brakes on the 98 model Yukon and maybe GMC will design a fix for this lousy system.
Brake pedal reached the floor when depressed and brakes keep on squeaking even after repair. Yh.
