I also go p0034 turbo/supercharger bypass control valve circuit low and my brakes do not work.

Is your matrix the xr model?

Have you double checked that you don't have any vacuum leaks?

Customer: replied 2 months ago.
I think I have a vaccum leak. Would this effect my Brakes? The pedal does not move, there is no power to the pedal.

It could. Is the vacuum hose that comes from the booster hooked up?

If it is hooked up it may be backwards. There is a valve built into the hose that only works one way.

Customer: replied 2 months ago.
all hoses appear to be hooked up an tight.

While its running pull the vacuum hose off the booster and see if there is vacuum present at the hose. If not flip it around.

Any luck with the brakes?

Got it repaired. Large intake/vacuum leak. Thanks for the advice.
