Brake Disc Caliper problems of the 2000 GMC Sierra 1500

Brake failure for the second time on the vehicle. Original brake lines were replaced 7 or 8 years ago due to failure at my own cost (rusted lines, leading them to fail as the brakes were applied), all lines were replace with gm replacement lines by a qualified technician. Original failure rendered the brakes 0% operational, gravity (uphill) was the only thing that stopped the vehicle. The most recent failure (on July 29, 2017) affected the brake line running to the front-right caliper, line failed where it crossed over the skid plate near the center-line of the vehicle up front by the lower radiator support. Line failed due to corrosion. Rear brakes appear to be working but are not sufficient to stop the vehicle in a safe manner. No accident occurred, line failed as approaching a light turning red while going uphill, rolled through the intersection prior to the light turning green for crossing traffic and was able to stop the vehicle as it drifted to a stop uphill. The quality of the gm brake lines are very suspect to say the least. The brake lines are dangerous and seem to be more susceptible to corrosion than any other brake line on any other vehicle I've ever owned, or any of my friends or family have ever owned. I can only imagine if the lines failed under different circumstances (while towing though mountains while going downhill for example, this would be a life-threatening situation). Please determine if these lines are faulty for the sake of others with these vehicles, and the sake of other motorists that could be impacted when the brakes on this larger vehicle fail. If they are found to be faulty owners should be notified that these brake lines are subpar, and that the manufacturer's replacement lines are also subpar.

The original flexible brake hose on the front passenger side of my 2000 GMC sierra vehicle failed resulting in the loss of front brakes. It appears that the hose is too long and the hose rubbed on the rim. The delco replacement that I purchased has been totally redesigned. It is much shorter and the connection to the caliper has to be angled at a 45 degree angle, so that the will be no contact with the rim. After replacing the passenger side, I checked the driver's side hose and found the same problem. The hose shows rubbing is occurring. I will have to put a replacement hose on that side also.

3rd time brakes/rotors have been replaced. This time I found I needed to replace the front calipers also. I have a detailed vehicle repair history from the day it was first purchased. The brakelines are in bad shape. While bleeding the brakes after installation, I had one of the lines rupture from corrosion. Upon inspection of all brakelines, I find it necessary to replace all brakelines for the safety of myself and my family and the other motorists on the road.

2000 GMC 1500 sierra 47,357 miles had a recall about a year ago. They cleaned and etched front brake lines at the calipers. Today towing a trailer with a car in the I-95 corridor between d. C. And baltimore I had to attempt a quick stop for slow traffic when suddenly I lost all breaking pressure and fortunately ended at the inner grass space barely saving a horrible crush with several cars lined in front of me. My front reservoir was very low, underneath the car at the driver's door level all 4 break lines were badly swollen and corroded,one at least was obviously dripping,and even the frame was corroded and metal chunks were easily knocked. Other sections look very rusty worse than a 65 Ford galaxie am restoring . And this at almost 48,000 miles .

The 1st prob left rear brake line broke. 2nd prob 37000 mi had to replace all rotors and pads because rotors rusted and chewed up pads,also replaced 1 caliper and brake line. 3rd prob 10/11 42115 mi other rear brake line broke. 4rth prob 12/11 42450mi brake line to the proportioning valve broke. The first prob I was rolling to a stop @ a stop sign. The 3rd and 4rth prob happened in my driveway. It should be a crime to put peoples lives in danger because of inferior materials.
