'''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.
