The secondary drains faster than the primary, particularly when you are bleeding the passenger side front. I monitor both as I am flushing first rear and left front (together), then right front. Both reservoirs will eventually empty, and the fluid in the lines will all flush as that happens.</div><div class=""><br class=""></div><div class="">Probably obvious, but thought I’d pass on what I’ve experienced.</div><div class=""><br class=""></div><div class="">Peter</div><div class=""><br class=""></div><div class=""><br class=""><div class="">
