Brake Fluid: Replacement

WARNING: This page is about a different car, the 2022 Subaru WRX. 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. Wash away with water immediately and wipe off if it is spilled by accident.
Do not mix different kinds of brake fluid.
Do not allow water or foreign matter to enter the reservoir tank.
Always use new brake fluid when replacing or refilling the brake fluid.
During the operation, keep the reservoir tank filled with brake fluid at "MIN level" or higher to prevent entry of air.

NOTE:

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.

Remove the wheels. Ref. to WHEEL AND TIRE SYSTEM>TIRE AND WHEEL>REMOVAL .
Drain brake fluid from the reservoir tank.
CAUTION:
When using a tool such as a dropper to adjust the fluid amount, do not use one that has been utilized for deteriorated brake fluid or other liquids.

Doing so may cause the sealing parts or brake fluid to deteriorate, resulting in a malfunction.
Replenish the reservoir tank with the brake fluid, and perform the same procedure as for air bleeding of 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, etc. (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.)
