FINAL DRIVEBRAKES pressure will cause surge of fluid through the small orifices of the brake system when the bleeder screw is opened and introduce air into the system by means of cavitation Small amounts of air can become trapped in the banjo bolt fittings at the master cylinder(s) and junction points of brake linesThese fittings can be purged of air by following standard bleeding procedure at these fittings (instead of the bleed screw on caliper) if necessary to speed the bleeding processThis is usually only needed if system was completely drained of fluidBleed each line connection, starting with the fitting closest to the master cylinder, working toward the caliper, and ending with the bleed screw Always torque banjo bolts and other brake system fittings to specified torque Change fluid every years, or when fluid is dark or contamination is suspected
