Was driving home and noticed that when the brake was pressed it had to be pressed harder to stop. Once arriving home noticed that brake fluid was leaking from under the driver side rear tire. The brake line is rusted, corroded and has a break in the line. This is absolutely unacceptable. *tr

Severe corrosion of the brake lines became apparent during a sudden application of the brakes which caused multiple brake lines to rupture and leave the vehicle with no brakes since a line from the master cylinder to the abs unit front left input and the abs to the rear t line blew simultaneously. When removing the damaged brake lines they literally crumbled to pieces due to corrosion. During the repair to the brake…

Upon applying the brakes on to a 1999 gmc sierra the brake line ruptured, spewing brake fluid onto pavement and causing near immediate loss of all stopping ability. The brakes were not applied with excessive pressure and the speed was less than 15 mph. Could there be a defect with the placing of the lines that causes these brake lines to rupture? Upon checking with friends and the internet it has become apparent…

Upon leaving my driveway to the first intersection the brake pedal went all the way to the floorboard. I got the truck home and parked it. I thought the anti-lock part was probably the problem. Expensive as that part is i just let the truck sit. One day i left a piece of cardboard under the truck and isolated the leak to two rusted out lines at the plastic clip on the frame. This area must hold moisture and doesn't…

I was parked in front of my home. I was getting ready to leave for work and i pressed the brake pedal down to start the truck and the brake pedal went to the floor.

My mechanic said it was caused by the brake line being corroded.…

On april 15 2010, as i was bringing my vehicle to a stop, the brake pedal traveled all the way to the floor. When i got under the vehicle to examine it i saw the rear right brake line was leaking brake fluid badly due to a break in the metal brake line. Again on 2/27/2011, i was stopping my vehicle at a stop sign and the same thing happened at a low speed. Only this time it was a front right brake line. Luckily in…
