Two problems related to brake light on have been reported for the 2002 Chevrolet 1500. The most recently reported issues are listed below.
Went to start truck. Pressed brake pedal. Truck started, pedal went to floor. Took foot off pedal. Let truck run for a few minutes to see if brake light would go off. It did not. Turned off truck. Checked around truck. Found brake fluid under truck by right rear tire. Check brake line near left rear tire. It is in bad shape and will likely fail soon. Two or three years ago, had front line fail below driver's seat. Replaced front lines. Rear lines did not look too bad at the time. With all new technology advances, chevy is now using inferior material. Dust guards around rear brakes of this truck are completely gone on both sides. Everything is rusting. Had 1975 Buick estate wagon for 22 yrs. It was in better shape when I sold it than this truck has been for the last several years. Chevy could do all the corporate double speak they want. Fact is this rust issue is a safety issue. I have friends that have a little older and newer 1500 and all have brake line issues and varying degrees of rust underneath the vehicle. I see where others have registered similar complaints. It is unfortunate that nothing will get done until there are serious injuries. (I see where you want a daytime phone number. If you call from a phone that does not have a NHTSA id, you will have to leave a voicemail. ).
As I approached a stop sign after traveling about 30 mph and slowing down for the stop sign I press the brakes and it went to the floor and press them a second time and possible a third before crossing traffic and failing to stop. I miss hitting a car by inches. This was all on an uphill incline. I cross traffic and was able to stop in a church parking lot by using the parking brake. After about the fifth time applying the brakes the brake warning light come on. No warning until then. After inspection the brake line next to the drivers side had rupture. The line let a trail of brake fluid for about 200 yards. The brake fluid was checked at oil change service four days prior and was full. Now it is empty. This is a major failure that should be corrected before someone is killed. I though that there was a secondary system to stop if one half of the system failed. Apparently not!!!!!.
