12 problems related to brake fluid leak have been reported for the 2004 Chevrolet Suburban. The most recently reported issues are listed below.
The brake fluid lines rusted at the area under the driver side wheel, causing the fluid to leak unexpectedly, thus rendering no brakes. The leak happened on my vehicle and another in this same area. The mechanic said there could be is a problem in the manufacturing of the lines due to the construction and because its too close to the wheel salt and road conditions causes this area to rust more easily. He's had a number of chevy sub. With this same problem in for repair/replacement.
Brake line (hard line) catastrophic failure. Unable to stop on coming to highway intersection using hydraulic brakes. Had to resort to applying parking brake to stop vehicle. On inspection main brake hydraulic line ruptured- fluid spewed on roadway and approximately 1/2 of fluid from master cylinder. Limited residual pressure from secondary was unable to stop vehicle without mechanical assist from parking brake.
Backing out of a parking space went to stop and brake pedal sunk to the floor abs and brake light came on I put the truck in park opened the hood the master cylinder had fluid then looked under the truck and under the drivers side door brake fluid was leaking from 1 of the 2 steel rusted lines had the truck towed to a repair shop the shop said the 2 lines from the master cylinder to the abs block had severe corrosion and the rest of the brake lines aren't much better im sorry guys but this is a serious problem to me I could have been killed or killed someone else im one of the lucky ones I guess so now the truck is in the shop having all the brake lines changed for a cost of $ 600. 00 and guess what we also own a 2003 tahoe with 90000 miles on it I guess they will have to be changed also same condition all brake lines rusted badly how many people must be seriously injured or killed before something is done about this problem its wide spread look on line how many people have gone through this its a shame make g. M do the right thing here.
Brake lines rusted through and leaked fluid from system.
I took the vehicle to local Chevrolet dealer for oil change and yearly state inspection. The vehicle passed the state inspection/emissions control test. I was not notified that there were any issues concerning the vehicle. The vehicle was driven 5 miles to home. Two days, started the car, but had no brakes. The brake pedal went to the floor. A warning light was on. There were puddles of brake fluid in the driveway. I had the vehicle towed back to the dealer. They informed me that te brakeline had completely corroded. The cost for repair was quoted at $800. From what I understand, this sudden and complete brake failure could have occurred at any time, even while driving the vehicle.
While driving in heavy morning rush hour traffic on a northern virginia interstate, brakes were applied for typical traffic slowdown. After releasing the brake, the warning light alerting driver of a brake issue came on. At that point, I tested the brake and the peddle sunk to the floor while quickly loosing braking resistance. I was able to pull over and stop the vehicle within about a mile. Looked underneath the drivers side and saw brake fluid leaking/dripping out of the brake line which was ruptured. Had to call a tow truck to take this to a shop for replacement of all of the brake lines. All of the lines were corroded. Checked online and saw that this was a "typical" issue affecting 2004 chevy Suburbans but that a product recall was not issued yet. I was thankful that this did not happen the previous day when my 16 yr old daughter drove the car to school.
Driving down highway coming to red light depressed brake pedal, pedal went all the way to the floor. Could not stop vehicle before going through red light, held down vehicle horn to warn other drivers which saved me from injuring/killing someone else or myself. After getting vehicle on shoulder of road noticed brake fluid dripping down the frame rail on the drivers side in front of rear tire.
On 8/30/14 I was driving down the road going about 25 mph when a car came out from a street on the left side and pulled in front of me without looking, I pressed down on the brakes quick and swerved to the right to avoid hitting him, he had no idea as I was swerving out of the way to not hit him, he was making his turn, I got on the horn and he just pulled over to the right and gave me a wave as to say he was sorry. Anyway, when I pressed down on the brake fast, it went all the way to the floor, I had total brake failure, all the brake fluid leaked out from the driver's side near the chassis, there was no stopping this truck. I don't see how they can say you are still able to use the brakes, you can't pump them. It is now sitting at the mechanics getting fixed, so far he told me it would be $600-$800 labor, I have not gotten back the truck yet as I write this. The brake lines were so rotted, it was only a matter of time, and I only bought this 9/17/13, the truck originally came from pennsylvania.
I had the vehicle in park, on a hill, and when I shifted it into drive, felt a pop in the pedal. Then the brakes would not hold the vehicle. I had a very difficult time stoppinf the vehicle due to the loss of brake pressure. The brakes pedal would just fall to the floor. My husband came out and found one of the rear brake lines was rusted and leaking fluid. The brake lines have visible rust on the outside of them.
Tl- the contact owns a 2004 Chevrolet Suburban 1500. While driving approximately 45 mph the contact depressed the brake pedal but the brakes would not respond. The contact applied excessive pressure to the brake pedal in order for the brakes to respond. The vehicle was taken to an independent mechanic for diagnostic testing. The mechanic stated the hydro boost would have to be replaced because brake fluid and power steering fluid was leaking. There was a recall under NHTSA campaign number: 05v043000 (service brakes, hydraulic) that could be related to the failure. The manufacturer was made aware of the failure and stated the VIN was not included in the recall. The vehicle was not repaired. The approximate failure mileage was 138,000. Da.
The brakes on my 2004 Chevrolet Suburban 2500 failed during an attempted stop. The pedal traveled all the way to the floor. Subsequent testing of the brakes revealed that there was at least one brake fluid leak from lines leaving the master cylinder which was spraying brake fluid onto the engine causing smoking. The vehicle was towed to a Chevrolet dealership for repair and I was told that the brake lines had corroded through causing loss of brake fluid and loss of braking capability. It was stated by the dealership that this corrosion was due to road conditions where salt is used on the roads for winter driving. The vehicle had approximately 42,000 miles on it when the brake failure occurred. The cost of the repair was approximately $2,500. The vehicle has never been used for snow plowing or spreading road salt.
While vehicle was stationary at idle I noted excessive brake pedal travel after placing my right foot on the brake. The brake pedal traveled all the way to the floor board and was very slow in return. I shut the vehicle off and visually checked the master cylinder and connections. I noted the master cylinder brake fluid reservoir was not completely at the full mark. I continued to observe the hydraulic connections and found no active leak and no fluid on the ground beneath the vehicle. I drove the vehicle to a repair shop in town (out of state visit) advising the shop owner of the problem involving brake travel. A mechanic determined the brake lines on my vehicle were routed along the vehicle frame, made of steel, and unprotected resulting in corrosion, holes, and active leaks. Two of the lines were repaired and now the remaining two lines require repair. I observed and noted corrosion of the brake line distribution system along the vehicle frame running to the rear of the vehicle and crossing over the right side. I believe the brake line corroded and failed immediately behind the driver's side located immediately next to the vehicle identification tag. This location was obscured from view because a plastic wiring harness is routed between the brake lines and exterior of the frame. I believe the placement of the plastic conduit conceals vision / inspection of corroding brake lines. I believe unprotected steel brake lines are subject to physical abrasion and moisture between the unprotected brake line and the vehicle frame resulting in brake line fatigue and water based corrosion resulting in holes and failure of the hydraulic brake system. I never observed the operation of the "brake" icon located on the vehicle message panel.
