Seven problems related to brake master cylinder have been reported for the 2002 Chevrolet Avalanche. The most recently reported issues are listed below.

1 Brake Master Cylinder problem

Failure Date: 01/02/2015

While driving my truck and towing a trailer, I lost almost all my braking power. Had to down shift and use the emergency brake to stop. Found that a brake line from the master cylinder to the anti-lock brake module (which is mounted under the drivers seat, great place) had rusted through and blew out. Found all the brake lines are severly corroded in this area and need to be replaced. Looks like gm used inferior metal brake lines in constructing the vehicle and located the anti-lock brake module in an area that gets severe exposure to the elements. The vehicle was totally rendered unsafe with the rupture of one brake line, which indicates the system as a whole is a faulty design. I was very luck to have been able to stop and not hit another vehicle.

2 Brake Master Cylinder problem

Failure Date: 10/01/2013

I was driving home around 9:30 pm. As I was going down a hill I stepped on my brakes and the pedal went to the floor. No brakes at all, no saftey features kicked in, no warning lights. Just a catastrophic brake failure. Luckily for me it was a small hill and I was able to stop by going into low gear and using the emergency brake. I turns out that the brakelines from the master cylinder to the abs control box were rotted and finally gave out. This is a 2002 truck with 62,000 miles on it. I know from previous experience with older cars that if a brake line fails, there is a valve that is supposed to cut off the open line so there is some brakes left. I repeat, no saftey features worked, no warning lights, no valve kicking in,nothing. This is a known issue with gm. A quick search on the web brought up thousands of hits on this problem. Just 20 minutes earlier I was on the nys thruway doing 65 mph. If I lost brakes at that speed and with the other traffic, there most certainly wood have been a crash and possible loss of life.

3 Brake Master Cylinder problem

Failure Date: 05/24/2013

I was traveling at 55 mph when I came to a stop light and while slowing down for the light my brake pedal went to the floor and ended up going through the light. It was a good thing no one was in front of me or I would have collided with their rear end of their car at 55 mph after looking into what happened I noticed my brake like has corroded enough to cause a leak which upon inspection all 4 brake lines running from the master cylinder to the brake management/ equalazation system was rusted beyond repair.

7 Brake Master Cylinder problem

Failure Date: 08/16/2005

Brakes work sometimes, half brakes,( were you have to pull the emergency brake to stop), or brakes go on by themselves were you have to pull over and stop and wait or cool your breaks until they cool down. ( because the breaks are smoking. )problem has been going on for 7 months. 2002 Avalanche. The vehicle has been in the dealers 7 times and the last time on 05/08/06 because I almost hit a child. They replaced my brake lines but brakes still lock up and go on by themselves, when you stop quickly. Gave the dealer the paper work on salt affecting the anti- lock sensors recall since I live in florida on 05/08/06 and told me in did not apply. My wife's 05 equinox went in for the exact same problems on 05/12/06 with no brakes at all except for the emergency brake and they want to replace her master cylinder. I told the dealer about the recall in the northern states and provided them with the recall paperwork and was blown off!. My truck came back today 05-12-06 with the exact same problems after being fix by the dealer.
