I've got a 96 Legacy Outback. Put new pads on the front wheels today. When I did, I disconnected the lines at the caliper instead of opening the bleed nut to get the pistons back. (it was much easier to get the pistons back with the entire caliper removed and line disconnected, plus got to purge some dirty fluid.) Reassembled everything, but the sun went down before I could bleed them. Pedal is currently uselessly hitting the floor.
I've replaced pads on a car or two in the past,but never lost any fluid in the process, so I've never bled brakes. I know it isn't a big deal, but after reading a couple of posts, I'm starting to get nervous. Couple of questions.
1. Do I have to bleed the REAR brakes even though they were untouched?
2. Should the fluid resevoir cap be ON or OFF? I understand that the fluid should not be allowed to empty.
3. I believe that I should bleed each bleed nut starting at the farthest from the master cylinder, but how do I know when I'm done? The goal is to eliminate air bubbles, is it very apparent when only fluid is coming from the bleed nut? Will the bubbles be forced to the brake first, or could I be leaving one in there that happens to be pushing out a steady stream of fluid?
4. I am assuming that the pedal will keep hitting the floor until all brakes are bled. At that point, the last bleed nut should be closed. Then it should take a couple of pumps to get stiffness back into the pedal and I'm good to go. Am I correct? Is there any other adjustments I need to make?
5. Is there anything I have forgotten or any rookie mistakes that will sink me?
I'd appreciate ANY input, I'm hitting this thing tomorrow one way or the other. Thanks!
