Here's why it's difficult and risky:
* Bleeding the brakes: After replacing any brake line, you must completely bleed the brake system to remove all air. This is a complex process requiring two people and specialized tools. Air in the brake lines significantly reduces braking power.
* Proper flaring and connection: Brake lines require precise flaring to create a proper seal with the fittings. Improper flaring can lead to leaks. You need specialized tools to create these flares correctly.
* Corrosion: Older Tahoes, especially those in areas with harsh winters, may have severely corroded brake lines. Removing corroded lines without damaging surrounding components can be very challenging.
* Routing: Routing the new brake lines correctly is crucial. The lines need to be secure, avoid sharp bends that could weaken them, and be protected from damage.
* Safety: Working with brake lines involves working with pressurized systems that contain brake fluid, which is toxic. Improper handling can lead to injury.
Instead of attempting this yourself, consider:
* Taking it to a qualified mechanic: This is the safest and most reliable option. They have the expertise, tools, and experience to do the job correctly.
* Watching professional videos: While this won't replace hands-on experience, it can help you understand the process better if you're considering DIY. However, remember this is still a very risky undertaking for a novice.
In short, while technically possible, replacing your own brake lines on a Chevy Tahoe is a highly complex and dangerous task best left to professionals. The risk of a brake failure far outweighs any potential cost savings.
