Three problems related to brake hoses, lines/piping, and fittings have been reported for the 1997 Chevrolet Blazer. The most recently reported issues are listed below.
While driving my 1997 chevy Blazer, I was turning to the left off the highway at 60mph. I applied my brakes which started my deceleration, suddenly the brake pedal went the floor. I pumped the brake pedal one more time with no resistance. I had to apply the parking brake and started making large s-turns to burn off the speed and manually downshifting the transmission. After I finally stopped the vehicle I checked the brake lines and found out that the front driver's side metal brake line had rusted through and was spraying brake fluid all over the place. This is the second time in 3 months that the brake lines have burst on this 1997 chevy Blazer. The last time the rear main brake line burst.
Left rear oem metallic brake line corroded on a 1997 chevy Blazer resulting in loss of braking power. Line was not damage, just leaks out of pipe every time you push the brake pedal. Line is attached to frame above left rear wheel axle. Upon inspection it looks rusted out.
This has been taken into the same dealer several times for brake problems without any satifactory answers. The last time was about 3 months ago when I finally gave up and have been looking at trading it off in the near future when I can afford to. At the last effort to correct the problem with the service mgr, he told me that the caracteristics of the brake pedal slowly go to the floor at a stop sign or lite is normal. He said" this is caused by the brake lines expanding" and is normal with the 97 Blazers. Braking problem still exists today.
