5 Most Common Chevy Silverado Brake Bleeding Problems
We all know that proper brake function is vital for vehicle and passenger safety. Thus, any inconsistencies in the brake performance require immediate attention. Reduced braking efficiency can result from brake bleeding problems. This process works to eliminate air from the system, which tends to cause a spongy brake pedal.
Difficulty in bleeding the brakes from your Chevy Silverado is likely to stem from several issues. It can be a result of air trapped in the brake lines, malfunctioning brake system, brake system leak, incorrect bleeding procedure, or faulty brake master cylinder. To pinpoint the exact issues, a thorough brake system inspection is required.
This article highlights the main causes of Chevy Silverado brake bleeding problems and how to fix them.
Most Common Chevy Silverado Brake Bleeding Problems
The Chevy Silverado truck is a source of pride for many of its owners, and for a good reason. It is one of the most reliable trucks in the market and is built to handle just about any road condition. However, just like any other vehicle out there, it is not without its flaws, including the occasional brake bleeding problems. If you happen to find yourself unable to bleed the brakes of your Silverado, you are not the first.
Chevy Silverado brake bleeding problems can be a result of many issues. They are as outlined below as well as their potential solutions.
Air trapped in the brake line
Sometimes, air bubbles are likely to be trapped in the brake lines. When this happens, it disrupts the flow of the brake fluid and causes a spongy brake pedal.
Fix
To solve this, you will need to adopt a different brake bleeding technique. This technique involves bleeding the brake line starting from the master cylinder, being the farthest, and working your way to the closest line. In this technique, a helper will come in handy to pump the brakes as you open and close the bleeder valve. This process can be repeated until you can no longer see any air bubbles—only clear fluid should flow out.
Contaminated brake fluid
Another common culprit is contaminated brake fluid. Over time, the brake fluid tends to absorb moisture which results in reduced braking performance. If this brake fluid is old or contaminated, it becomes difficult to effectively bleed the brakes.
Fix
If you are dealing with contaminated brake fluid, it is best to flush the entire brake system and then replace the brake fluid with a fresh and clean one. This process goes a long way in ensuring that there are no contaminants or moisture in the system.
Malfunctioning brake components
If you happen to have recently replaced any of the brake components or suspect an underlying issue with the system, then it could be a faulty brake line, master cylinder, or brake caliper. These are the most likely culprits in this case.
Fix
Inspect the aforementioned components for any signs of malfunction or damage. You may have to replace any faulty parts where necessary to guarantee optimal brake operation.
Brake system leak
Any leak in the brake system is likely to introduce air into the system. This makes it difficult to properly bleed the brakes.
Fix
You are advised to inspect the brake lines, master cylinder, calipers, and connections for any signs of leakage. In case of a leak, replace or repair the damaged component before you re-attempt bleeding the brakes.
Incorrect bleeding procedure
It could also be that you are just not doing it right. There is a bleeding procedure that is specific to your Chevy Silverado model, and you must follow it. Following the correct procedure ensures that all the air is successfully expelled from the brake lines.
Fix
As mentioned above, different car models have different bleeding procedures that are specific to them. You can always consult your owner’s manual or seek the services of a professional mechanic to get the right bleeding procedure and sequence.
