I lost braking power after boosting today. I can drive around not in boost and have brakes. Is there a check valve on the brake booster line cause I don't find one. Please help thanks

Some have it tim, some do not. Looks like you need one eh? I've never had this issue so I don't know the details but you can find out how to install the check valve by searchin. I've read the post, just dont know the details.

i'm not sure about earlier year models, but the 98-99 have the check valve press fitted inside the hose. you can't see it but if the squeeze the line you can feel it. i think mitsu. sells the hose/valve as one part.

Why are you hitting the brakes while in boost anyway? let off the throttle, brake.

Left foot braking? "Launching" from a roll? Building boost pressure while braking in a turn to get ready for accelerating after the apex?
Pressure from the turbo even after decel keeps the booster from working for a few seconds. I get it every time I make a pass. Tim, I wish I had the part number, but Nissan makes a fucking awsome check valve that works for this, I used it on my 350z. Try a dealer and tell them to look up a check valve, if your lucky the parts guy will find it.

Hey guys, just reading this post and starting to get concerned for when i start boosting my car in the next few weeks, anyhow, where could you find (how much?) a check valve to fix this problem? does anyone besides nissan carry somthing like this? (sorry may be a dumb question just wanting to know)

I used a 800psi industrial check valve. Works great. It has a all brass body.
