Brake Hoses, Lines/piping, And Fittings problems of the 2006 Chevrolet Suburban

Sudden and complete brake failure due to a broken rear brake line. Brakes worked normally and at the next stop they went completely to the floor with no braking action. I had to use down shifting to slow and then a snow bank to completely stop. There was no indicator warning lights until the brake pedal hit the floor and went out immediately after the pedal was released. This happened on a city street with no traffic at 3 am on my way to work. I was driving straight at about 25 to 30 mph. After looking at the brake lines they are dramatically rusted. The service shop has explained complete replacement of all lines needs to be done (appointment to do this is 3/20/2019).

While towing the family boat on secondary roadways, I attempted to stop in heavy traffic, when I pressed on the brake pedal it went completely to the floor and both the truck and boat continued rolling towards stopped traffic. I was only able to stop the vehicle by manually operating the parking brake. Had I not had the presence of mind to utilize the parking brake I would have collided with the traffic stopped in front of me. Upon inspection I noticed a large mount of brake fluid under the driver's side front wheel. I transported the vehicle to my service station where they placed it on a lift and showed me the extensive corrosion on all of the brake lines and transmission cooling lines. The line which had failed resulted in no braking capabilities whatsoever. There is not one serviceable brake line left on the vehicle. The vehicle has 75k miles on it and is immaculate both inside and out and has been regularly serviced. The brake failure resulting in a total loss of brakes, came without any warning.

Corrosion of hard brake line at driver / left side rear, partly hidden from view. Not seen during inspections. Condition discovered following surface roadway incident. Vehicle was stationary, in drive, pointed downhill at stoplight. Brake pedal slowly started going down. Pumping brake helped a bit, but soon the pedal started falling again and the vehicle started moving forward. Putting vehicle in park prevented vehicle from striking stopped vehicles in front. Got off the roadway shortly thereafter and discovered the corrosion and lead mentioned above. Vehicle is currently in repair shop with $1800 service bill. Body is required to be lifted off frame for replacement lines to be installed and that is *very* labor intensive. Researched online and found NHTSA has investigated these vehicles during their production run of 1999-2006 on c/k/suburban/tahoe models. Vehicle was purchased in washington state, where salt is not used on roadways.

Driving at 60 mph and applied brakes hard to avoid hitting deer that came on to road. Vehicle began to slow then suddenly lost nearly all braking power as peddle went to floor . Went well past an uncontrolled intersection that was thankfully empty of traffic. Subsequent inspection revealed two burst brake lines where 4 lines are grouped on frame near back of front driver door. Severe rust.
