Master Cylinder, Brake: Removal

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

The vacuum in the power brake booster must be pumped down before removing the master cylinder to prevent the booster from sucking in any contamination. This can be done by pumping the brake pedal while the engine is not running until a firm brake pedal is achieved.

NOTE:

Before proceeding, Refer to CAUTION and WARNING .

With the engine not running, pump the brake pedal 4-5 strokes until the pedal feel is firm.
Remove the engine cover, if equipped.
