Bleeding brakes on a 2007 Lexus LS460L after replacing brake lines requires a specific procedure and a scan tool capable of clearing ABS codes. This process differs from traditional bleeding methods due to the vehicle’s advanced braking system. Here’s a step-by-step guide based on a successful DIY experience.
This method requires two people: one to operate the brake pedal inside the car and another to manage the bleeding process at each wheel. A scan tool, preferably a Techstream for optimal Lexus compatibility, is crucial for clearing the ABS codes that will inevitably trigger during this process. A pneumatic bleeder is recommended for efficiency, though a traditional hose and can method might work with adjustments.
Begin with the rear brakes. With the car running and the passenger-side rear wheel raised, attach the pneumatic bleeder to the bleeder screw. While the driver presses and holds the brake pedal to the floor, briefly open the bleeder valve to allow the vacuum to extract brake fluid. This should only take a second or two. Close the bleeder valve and have the driver release the brake pedal. An ABS code will likely appear on the scan tool at this point.
Use the 2007 Lexus Ls460l Techstream Scan Tool, or a compatible alternative, to clear the code. Repeat the bleeding process (depress pedal, open bleeder, close bleeder, release pedal, clear code) two more times for each corner. Maintaining a full brake fluid reservoir is essential, as this procedure consumes fluid rapidly.
After completing the passenger-side rear, move to the driver-side rear, then the passenger-side front, and finally, the driver-side front. This specific order is important for proper bleeding. Each corner should undergo the three-cycle bleed and clear process.
This method has proven successful in resolving ABS codes triggered by brake line replacement. It’s important to note that while a generic OBD-II scanner might clear codes, a Lexus-specific Techstream scan tool offers the most comprehensive diagnostics and functionality for a 2007 Lexus LS460L. After completing the bleeding procedure, monitor the ABS system for any recurring codes to ensure the issue is fully resolved.
