Wilwood brakes

My son got front calipers for his Miata. Each caliper has 4 nipples. I can not get fluid to come out of any of them pumping the brakes. Came with new brake lines too. I believe I was suppose to start with the front right top nipple furthest out, and then do the inner one. Then go to the left wheel which is next to master cylinder. Any suggestions?
Thanks

I would suggest getting a "Power Bleeder" as when I was racing the pair of 914s we had that was the best way to clean out the brake lines and calipers. Used to do a bleed after every race weekend. If his car has anti-lock (abs) brakes I am not sure how you would do it?

I tried my bleeder too. Maybe the master cylinder needs to be bled.

If you didn't bench bleed the master. You'll never get fluid to the calipers

So is it similar to bleeding the calipers? A bleed valve on the MS?

First thing, make sure all the bleeder screws on the calipers are facing upward. Seen that mistake more than once.

I agree, master cyl. would also need to be bench bled first, assuming you ran it dry. Google bench bleeding. You should be able to do it with the cyl. in place.

One other thing to check is the ABS system. Not sure about the Miata, but a lot of cars need to have a computer hooked up to the OBD2 port and put the ABS pump in "bleed mode".

I think I've only seen bleeders on a sports bike mc.

You pump the master cylinder with a full reservoir until the fluid doesn't have bubbles. Simple. Easier on a bench, but as said you can do it on the car.

Did you fill up the calipers before you put them on the car?
