Chevrolet Silverado 2500 spongy pedal problems

Filed Mar 21, 2024 · Brakes, Transmission · AZ

This truck has had ongoing issues with the braking system. From the point of purchase Ive noted and informed the dealer of a very soft brake pedal pressure, and its gotten to the point where the brakes have to be pumped to get enough braking power to stop the vehicle at lower speeds, at highway speeds the vehicle is not able to stop in an emergency braking situation without pumping the brake pedal to build pressure, and especially when loaded or towing a load under the recommended gvwr. This problem is magnified by the fact that since day one the rear brakes have been wearing at a much greater rate than the front brakes. As indicated by the vehicles on board diagnostics display. This has gotten to the point where the rear rotors are warped and the rear brakes stick at a stop and you can feel the release when you apply the throttle. This vehicle has had to have the rear end rebuilt not just once but now going on the second time. A GM engineer that came to look at the truck avoided addressing the brake issue after the dealership requested General Motors assistance from their tech and then engineering department. This vehicles braking system represents a great risk for injury and or accident in its present condition, and the dealer Bradley Chevrolet Lake Havasu City Arizona as well as General Motors Customer Care Dept. has been made aware of this and has yet to take any action. This incident started back in Nov 22 and has been ongoing.... I believe this vehicle in its current state reflects a clear and present danger if driven .

Same issue as current recall on 1500 series trucks but not on the 2500 series (which mine is). Pedal now very spongy, have to pump them to get adequate braking. This occurs at highway speeds and local driving. Panic stops require engaging the parking brake to prevent a crash. Have had it in twice for service but all they are trying to do is reprogram. There are other issues with the vacumn pump, hydroboost, master cylinder which they are apparently unwilling to address. Why the 2500 and 3500 trucks were not included in the recall is the question of the day. I am not driving the truck any more than necessary as it is unsafe. This complaint is a matter of record of the issue.

Takata recall. This is my third event relating to brake line failure. This event, I was driving and noticed the brake pedal became spongy. Further inspection showed a leak of brake fluid above my fuel tank and at the left front tire. There appears to be fluid on the frame of the truck behind the driver side front tire. I have not been able to inspect the line above the fuel tank at this time. I have attached a photo of the wet frame behind the left front tire. It shows a rusted brake line. The first two events my juvenile son was driving. For all events we were extremely fortunate to be operating in our yard, so no accidents. The first two events happened approximately 2 years ago. Inspecting the brake lines that failed, showed that these lines were severely rusted. As a matter of fact, inspecting the lines that are visible, they all show signs of rusting. I am fortunate to be able to repair this type of malfunction, so I do not have any dealer paperwork to document the repairs. I have no doubt that there are many other owners of general motor trucks out there who have experienced the same issue and like myself decided to just repair it themselves, avoiding the complaint process. Or, I question if, like myself, they even have knowledge of how to file a complaint. Please forgive me for the last expression of frustration. Finally, how many people are going to have to die for this to become serious enough for a recall order? Thank you for your attention to this very serious matter!!!

About two days ago when I pushed my brakes they felt spongy and when I pulled into my driveway I could smell brake fluid.today I went to move the truck to check it out. The brakes were even more spongy,so I pushed them hard and the brake line ruptured above the fuel tank.the front brakes would not stop the truck, so I had to use the transmission to stop the truck. It must have sprung a small leak two days ago when I noticed the fluid smell and spongy feel.good thing I wasn't driving on the road when it burst today, because it would not have stopped.

Everything appeared normal when I was driving to the bank. As I was slowing to make the turn into the bank the brakes felt a little spongy. As I pulled up to the atm brakes continue to be spongy. Finished at bank and cautiously started driving home. First stop light, I had to gear down to slow to allow me to stop as the brake hit the floor. Pumping helped me stop in time to not hit the car in front of me. I should have probably called for a tow at that point, but only had back roads left to get home. Drove very slow (less than 5mph) by time home had no brakes left. Going slow enough to hit curb opposite of my driveway to stop and then backed into uphill driveway so gravity stopped me to put in park. Btw - no emergency brake to help, that is not working. Got out and a steady stream of brake fluid was coming out from under the drive side door. Looked under vehicle and saw fluid leaking from corroded (rusted) brake line between master cylinder & ABS box. Took a look at all the other line and surprised to see how corroded all of the brake lines are. I was also kind of surprised to see how horrible the entire underside, including frame, have rusted for a 10 year old truck. Definitely very upset the brake lines are that corroded and will all need to be replaced to provide confidence another one is not going to burst. I'm just very happy I didn't get in an accident and I sure hope it doesn't take someone dying for gm to issue a recall. Given the size of these vehicles and the shear damage they could do to property or human life should be a concern to gm. I'm a huge fan of gm/chevy trucks, but pending what happens may dictate my next truck. My truck has been sitting as I have not had time to try to repair myself or money available to be able to take the chance at how much a shop is going to charge.

Driving a 2004 chevrolet 2500hd 4x4 6 liter crew cab with 143005 miles. Traveling at 55 MPH as I approached my turn onto a side street at approximately 100 yards out I applied brakes to reduce speed to 15/20 MPH to make 90 degree downhill right turn. I experienced a very spongy brake for a couple of seconds followed by the brake pedal going completely to floor. I pumped brakes several more times with the same brake pedal response and zero braking. My speed had only dropped to about 40 MPH, too fast to negotiate my turn. I continued on the hwy to the next street using my parking brake and down shifting. Safely parked, I got out of truck and noticed a large amount of fluid was running on the ground, drivers side forward part of cab, resulting in a complete loss of brakes. My left front steel brake line located on top of frame under driver side at firewall had burst. All 4 brake lines in that 4" long area were badly rusted. Removed all the brake lines and that appears to be the heaviest area of heavy rust.

On restarting the vehicle moments after having driven it without issue, the brake pedal felt spongy, and with more pressure, sunk to the floor. Fluid was found to be running off of the truck frame under the drivers door. No warning light came on at the time. Later, apparently when the fluid had drained down enough, the brake warning light came on. On inspection, all of the brake lines were found to be very badly decayed just forward of the ABS unit, with one having failed. This is not an off-road truck. It has had conservative road use. Fortunately, I was not towing my 8000 pound trailer at the time. I recently sold a 1972 chevrolet which had never required any brake line replacements. Why are these relatively new trucks brakes all failing?

Tl* the contact owns a 2004 chevrolet k2500 (n/a) extended cab. The contact stated that while driving 25 MPH and applying the brakes, the brakes became spongy and abnormally traveled to the floorboard. The vehicle was driven to a local mechanic, who advised the contact that the brake line was corroded and caused brake fluid to leak. The mechanic repaired the brake tubing from the master cylinder to the ABS controller and also, the tubing for the two front wheels. The manufacturer was notified of the failure. The failure mileage was 66,520.
