How do I bleed a multi-piston caliper with the four-bleed screws?
After the master cylinder has been bled, begin bleeding the calipers starting with the wheel farthest from the master cylinder, usually the right rear and start with the upper outside nipple, then move to the upper inside nipple (never bleed the lower nipples). Repeat the process with each wheel, moving successively toward the wheel closest to the master cylinder. For best results the upper nipples should be pointing straight up because air migrates to the top of the chamber. If you have any questions, please contact a Wilwood Sales Technician at 805-388-1188 or email Sales/Tech Support.
