When reconditioning or replacing brake calipers, it is generally sufficient to bleed the relevant brake line as follows.

The brake pedal must be depressed throughout the operation. This is so that the brake system is not drained of brake fluid.

If the braking system has been completely or partly drained, bleed the whole system. A bleeding unit must be used that can pressurize the brake system to 0.2-0.3 MPa (29.0 - 43.5 psi).

NOTE: Use only Volvo Genuine Parts brake fluid specification DOT 4+.Never reuse brake fluid. Always keep brake fluid well sealed in its original packaging.
