When manually bleeding the brake system on a diagonally-split front-wheel-drive vehicle, after bleeding the right rear wheel, which wheel should be bled next?

In a diagonally-split brake system, the bleeding sequence is crucial for ensuring that air is effectively removed from the lines and that the brakes function optimally. After bleeding the right rear wheel, the next wheel that should be bled is the left rear. This sequence allows for a balanced and thorough removal of air from the system because the diagonally-split design connects the right rear to the left front and the left rear to the right front.

By bleeding the left rear after the right rear, you are ensuring that the system maintains proper pressure and that any air trapped in the lines affecting the left rear brake is eliminated. This method supports the performance reliability and safety of the brake system since each diagonal pairing affects the corresponding diagonal wheel.

Other options would disturb the intended function of the brake system. For instance, if the right front or left front were bled next, it would not continue the systematic approach necessary for the diagonally split configuration. The option stating it does not matter disregards the specific sequence fundamental to this type of brake system and could lead to inefficient brake performance.
