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.
Warnings
- 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
- Suck out old fluid in reservoir using a miti-vac or a turkey baster.
- Top off with NEW UNOPENED DOT-4 PLUS fluid ONLY!
- 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.
- Do a manual check of brake pressure
- Make a final check of the level of fluid in the brake reservoir.
- Record Brake Flush in Maintenance Records.
- Dispose of old brake fluid responsibly .
TIP: If possible alternate brake fluid colour from one flush to the next. The difference in colour gives good confidence that everything is flushed out.
Quantity of Brake Fluid Required for a Thorough Flush It will use about 3L for a full and thorough flush.
The following video shows how to completely flush and replace the Brake Fluid using the Pressure Vacuum method.
