Lose brakes at full crank

Hey guys. I just had my fabtech spindles installed and its been holdin up really well until a couple days ago i had to do a 3 pt turn and when i cranked the wheel all the way and the brakes went.. i had to pump the brake and it came back. But i remember the shop giving me the steering stops cause they didnt know what to do with them.. so is that the problem? i really have no idea and i need to get this fixed so i dont go crashing into people.
Here are some pics of the lift.

try re-bleeding them, to get air out of the lines. Also you may want to have someone sit in your truck and have them crank the wheel and you can look underneith to make sure nothing is being pinched

did the shop extend the brake lines?

the first thing he checked was making sure the brake lines were long enough at full crank, cause i was there to turn the wheel all the way left and right. So the brake lines are fine, its only after a full turn that the brakes disappear.

It's normal. What's happening is that there really aren't any "stops" when you turn. So, with the new rotor position, the brake caliper gets compressed between the spindle and the lower a-arm at full lock. This forces brake fluid back into the master cylinder, just like when you compress the caliper when changing the pads to put the new ones in.

Then, when you pump the brakes, it first has to refill the caliper to put the pads into contact with the rotors. After that, when you release and press, you have brakes again.

My spindles do the same thing. Learn to drive it and warn anyone else who drives the truck!

You can try to make new stops -- I haven't done any that have lasted or worked that well yet.

I was going through the install instructions from the Fabtech website and it said you are supposed to grind down on something.. and I know they didnt grind anything, so could it also be that? cause my turn radius is really really pathetic now if this is the best its gonna be i can live with it.. im just always nervous now about parking because i dont want to not have brakes and run into another car. Here are some pics I saw of the "rubbing" of the spindle and LCA

If THEY didn't grind, then you need to or you are risking a failure of the spindles as well as the lousy turning radius.

The outer edge of the lower arm has to be ground or it rubs the bolts that secure the axle part of the spindle. Basically, the lower a-arm needs grinding in a couple of places.

Get it done! It's not a casual "detail" at all and if the installer didn't do it, they don't know their butt from a hole in the ground doing spindle installs. I did my own and didn't grind and had to take the lower ball joints free again to do it after I had problems. I didn't know my butt...either!

Even after the grinding, the brake problem will be there, but your turning radius increases and you don't need to put it at lock so far. Also, you won't damage the spindle bolts.

Thanks big time n3elz, u are my savior lol when you sent me the first reply i was worried that my turning radius would be like that forever (which would have sucked) but now all is better and i will take it back to have them do it right. Thanks for the help!

Mine did the same thing, all that you have to do is take a handheld grinder and grind down that little cicular part in the first picture that is located on the frame that is what is compressing the caliper, after you do that no steering stops are need and your brakes will be fine.

Absolutely. However, since he paid for the install, I think he should insist they do it right this time. If they refuse or don't do it completely, he can still do it himself with our expert guidance, lol.

Uhh..is this something that most decent garages will already know to do?

I'm getting a fabtech spindle lift in the near future and I'm wondering if I have to tell the garage this or should they already know?

My brakes do the same thing and i have the lift spindals also. i just learned to live with it. I know it may be diffrent at first but you will get used to it and it will be safe.
