Pictures of how I fixed the brakes on my 87-95 Nissan Pathfinder.
Bleeding the brakes.
While I've got the wheels off and am staring at the brakes, I'll change the brake fluid to prevent rust, and get out any air bubbles.
I'm going to suck all the old fluid out through the brake cylinder bleed nipples, and refill the system with new fluid into the brake fluid reservoir under the hood.
So first I sucked out as much old black fluid as I could out of the reservoir.
I started at the brake cylinder furthest from the reservoir,
and worked my way toward the reservoir.
So that's right rear, left rear, rf, lf.
I attached some clear plastic tubing
and covered the threads with lithium grease to prevent air from getting in.
Apparently other types of grease ruin the brakes if they get into the system.
I had to remember to attach the wrench over the tubing
so I could open and close the nipple.
I used the large syringe to suck out the brake fluid.
Open nipple, suck syringe, close nipple, dump from syringe into jar, fill reservoir with new fluid,
repeat until clean fluid comes out.
A couple times I sucked too hard... Ahem...
I sucked too hard, and bubbles got sucked into the loosened threads of the bleed nipple,
and came out the hose into the syringe.
This looked like air in the lines, but I sucked slower and the extra lithium grease helped keep air out and it was fine.
- Then I did the other rear, then both fronts. That's it. Took some time, but not rocket surgery.
- Next I sold out to make 02¢
so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.
But no minivans!
- Then I finished my beer.
Also front hubs, disks, pads, and rear disks in the menu on the left.
