Remove/install:
- Remove wheels
- Check brake lining thickness and brake disks (61). Inspect condition of brake disks. Check brake lining thickness. Only replace brake pads and brake disks (61) in complete sets if necessary. If the brake pads have worn down to beyond the wear limit, the bar between the sealing groove and dust cap may be damaged; therefore: Inspect brake system for leaks with pressure tester.
- Remove brake disk. Do not detach brake hose, instead attach brake caliper to vehicle so that it is free of tension. Do not kink or tension brake hose, as otherwise it will be damaged.
- Remove locking bolt (64) and remove brake disk (61). Installation: Replace securing bolt (64)
Clean:
- Clean contact surfaces and seat of brake disk (61) if necessary.
- Lightly grease seat of brake disk (61) using Hot lubricating paste.
- Install in the reverse order
Checking:
- Carry out brake test on the test stand
Torque specifications:
- Locking bolt of rear/front axle brake disk: Nm 10

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.
