brake boost problem

[AKty92]

Hey guys ,,, So I'm playing around with the Ty ,, and I find a street with no traffic so I stop and try a boost launch ,, When I start to build boost the brakes wont hold at all , the boost guage is not even building any boost yet , I'm still reading in the range of vacum on the stock boost guage ,, I know the stock guage isnt very acurate but the Ty should boost at least into positive presure before creeping foward,, I looked at a few trhings ,like brake fluid , the booster is not leaking , no fluid leaks either , no ABS light or brake warning light ,, nothing looks out of place ..

Any ideas ?????? I'm stumped.

Re: brake boost problem

build up pressure in the lines by putting into N reving it while holding break down hard...you'll feel the brake "sink" further toward the floor...maintain brake holding and they try to build boost.

I had the same problem.. except after a few weeks the abs finally thru a code which prompted me to delete it.. now it'll hold up to 7 no problem(haven't tried anymore) but both my back wheel cylinders in the drums blow soo
