Three problems related to brake fluid leak have been reported for the 2003 Chevrolet K1500. The most recently reported issues are listed below.
I was approaching the intersection and the light turned yellow I tried to slow down and my brakes went directly to the floor not able to a stop, I speed up little to make it thru the light and pulled over in to a vacant lot to I came to a stop. Then the abs light came on and service brakes system popped up. I got out my truck was leaking brake fluid from driver side under the driver seat. Brake lines busted.
After making a panic stop, the dashboard brake warning light came on alerting me to have brakes serviced. Pulled in to parking lot (after the light) and found brake fluid dripping from under the truck from the brake lines leading into the abs controller and from a sharp bend in the line that operates the rear axle. Lines had rusted and leaked brake fluid.
I was driving my 2003 silverado on the local highway pulling my 7 x 14 trailer in traffic and went to apply the foot brake pedal and it went to the floor with no signs of anything wrong, tried to pump the pedal and nothing went straight to the floor with no help of stopping, the only thing that kept me from a crash was the trailer brakes and the e-brake of the truck. I got off the highway and checked the brake fluid and both front and rear were empty, I started to look under the truck and saw were the fluid was dripping from the rusted thru brake lines and down the frame rails, now with no brakes and pulling a trailer I had to call a wrecker and have the truck and trailer towed 35 mile to my mechanic and replace 4 rusted brake lines that run under the truck, mine rusted thru almost right under the drivers door. .
