Four problems related to brake master cylinder have been reported for the 2002 Chevrolet Suburban. The most recently reported issues are listed below.
The rear brake line failed for the second time and caused me to have accident. The issue is that the front brakes did not stop the vehicle and the brake pedal went to the floor. When this happened the first time 2009 the dealer changed the master cylinder and other brake components stating that is why the front brakes didn't work however this failure was exactly the same as the first incident absolutely no brakes.
Driving down l street in omaha, nebraska approaching 96th street. Brake pedal goes all the way to the floor and vehicle would not stop. I was able to pull to the side of the road just before light at 96th st on a slight hill which assisted vehicle stopping. The brake master cylinder was low. The car was towed to yeck's auto in bellevue, ne. Had I been following other vehicles closely or approached a quick changing yellow light the vehicle would not have stopped. Yeck's auto has since determined the brake lines failed. After internet investigation yields that gm has known about this defect. No warning lights, no indication of a problem. This vehicle needs to be recalled. The vehicle has been serviced at beardmore Chevrolet in bellevue, ne at prescribed intervals since day 1. Gm saying this is normal is frankly unacceptable. How many people have not been as lucky as I was on this day.
Travelling downhill toward a t-intersection, applied brakes and pedal went to the floor. Missed an approaching vehicle from the left by inches as I swung to the right, thru a stop sign. Returned home, thinking a rubber brake line had failed. Upon inspection, the steel brake pipe approximately ten inches in front of the right front caliper had split open due to corrosion. When I inspected the tubing prior to purchasing replacement parts, I discovered virtually all the steel brake lines were corroded to the point of failure, and in fact, I created another break in the same line as I attempted to loosen it from the plastic hold-down clamps under the left frame rail. Accessing the brake lines as they are routed between body and frame proved almost impossible, and am currently awaiting a recovery vehicle to take the truck to my inspection mechanic for replacement of all brake fluid lines/hoses from the master cylinder to the ebcm to each wheel caliper. The factory service manual mandates a minimum of 3/4" between any parallel brake lines, presumably to prevent bridging with mud/debris which might abet corrosion. In many cases, my steel brake lines were within 1/4" of one another. Some steel lines lay against steel frame rails with no clearance. This, however, would not account for the level of corrosion I discovered throughout the entire underbody of the truck. The only non-corroded portion of my brake system is the two lines immediately from the master cylinder downward to where they travel rearward along the left frame rail. Everything else is at the point of failure.
Brakes failed prematurely due to rusting brakes lines from master cylinder without warning on I-94.
