Brake Fluid Replacement
Regular Flush Every Two Years
Brake fluid DOT4 is hydroscopic (absorbs water) and needs to be exchanged every two years under the maintenance schedule. A local dealer quoted $95 for this task. Plan for between 1-1.5 hrs if you DIY.
- It is critically important to use the DOT rating specified in the owner’s manual.
- Brake fluid is hazardous. Wear latex gloves, safety glasses, and protect the paint of your car.
DIY Brake Fluid Flush

- Connect Power Bleeder which has been filled with NEW UNOPENED DOT-4 PLUS fluid!
- Pressurize the brake system with the Power Bleeder (138KPa (20 psi) via the integrated pump).
- Bleed all four callipers, LR, RR, LF and then RF.
- Inspect for leaks.
- Depressurize the system, CAUTION: DO NOT SPRAY THE FLUID, otherwise you will be getting a new paint job.
