Consumer Description

Took truck to dealer with concern of higher than normal braking force needed. Couldn’t verify concern. Looked today under the steering column and the brake booster is leaking fluid inside the cabin of the truck when the brake pedal goes through the firewall. There was Almost no brake fluid inside the reservoir causing the brakes to fail with no warning. Looked at similar trucks and all have brake fluid leaking from the same location. With as little as 10,000 miles. Mine has 22,000 miles and it’s failed requiring complet replacement of the brake booster. Taking to the dealership to replace the complete brake booster assembly when part is available. This is a 21 Chevy 2500 truck that pulls up to 18,000 pounds. higher than normal braking application needed, can be deadly or lead to complete brake failure whether loaded towing a trailer at a weigh of 25,000lbs or even the 7,000 pounds empty the truck weighs would reasonably result in the loss of someone’s life. Only thing that drew me to this concern was a harder application of the brake pedal and noticing brake fluid under the dashboard. Would gladly allow anyone to inspect my truck.
