Three problems related to brake disc caliper have been reported for the 2003 Chevrolet 1500. The most recently reported issues are listed below.
Came to a stop but the pedal felt soft, went two more miles to my destination and brakes felt even softer. When I went to leave I noticed a puddle under the drivers door, I put some on my finger to smell it and knew it was brake fluid. I took it to my mechanic who said it was a blown brake line caused by rust, he said he has seen this on alot of silverados. I called my chevy dealer and they didn't offer any recalls or discounts so I had my mechanic replaces all the brake lines because they were rusted as bad as the blown line , also had to replace two calipers because the bleeders were so rusted they couldn't be removed. Total cost 850. 00 I've had alot of trucks with alot more miles and never had problems with the brake lines. I think g. M. Should reimburse at least 50 % of the cost.
Severe corrosion on all steel brake lines - very close to rusting through at left rear caliper to axle mount and along side rail of frame.
The vehicle went through NY state inspection on March 28, 2005 and passed although the front end of the vehicle was shaking. Four months later the vehicle was taken to the dealer. They determined that the rear rotors were rusted and pitted. Gm will only reduce the price from $225 to $79, although it was covered under the warranty. They said it was a wear or rust issue. But the front brake rotors and calipers were fine. Gm was not honoring the warranty. The intermediate shaft was replaced due to noise.
