Brake Fluid: Replacement

WARNING: This page is about a different car, the 2021 Subaru Ascent. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Do not let brake fluid come into contact with the painted surface of the vehicle body. Wash away with water immediately and wipe off if it is spilled by accident.
Do not mix different kinds of brake fluid. Mixing different brands of fluid, or mixing different grades of fluid (even if they have the same brand name), may lead to severe accidents due to reduced brake fluid performance.
When refilling brake fluid, do not allow dirt or dust to get into the oil reservoir COMPL.
Always use new SUBARU genuine brake fluid when replacing or refilling the fluid. Do not reuse drained brake fluid.

NOTE:

During work, keep the oil reservoir COMPL filled with brake fluid to prevent entry of air.
Operate the brake pedal slowly and depress it fully.
For convenience and safety, perform the work with 2 people.
The required amount of brake fluid is approximately 500 mL (16.9 US fl oz, 17.6 Imp fl oz) for the entire brake system.

Lift up the vehicle.
Remove both the front and rear wheels.
Drain brake fluid from the oil reservoir COMPL.
Replenish the oil reservoir COMPL with the recommended brake fluid, and perform the same procedure as for bleeding the brake line on each brake caliper. Ref. to BRAKE>Air Bleeding>PROCEDURE .
NOTE: Repeat the full stroke depressing operation of the brake pedal slowly, until new brake fluid comes out from a transparent vinyl tube. (On each brake caliper, 20 times or more of pedal operations is necessary in order for new brake fluid from the master cylinder assembly to come out from the bleeder screw.)
