Replaced my brake booster with OEM replacement...Pedal pressure is good but considerable loss in braking power...like stepping on the brakes when the motor is off. Brake woes started after I installed ITB's...I wonder if the long hose from the booster to the intake manifold has something to do with it?

 

put a gauge on it and check how much vacuum you have to the booster. x- reference that with a fsm or haynes.

 

But braking power was fine after itb install...except it was mushy. Initially, pedal pressure was fine but was slowly losing pressure that's why I replaced the brake booster. Now brake pressure is good all throughout but no braking power...Like I said, it feels like the motor is off or something

 

Did you adjust the booster rod to the same length as the original one was?

I can't see the longer vacuum hose being a problem....

 

sometimes people mix up fuel line and vacuum hose. ive seen fuel lines pinch shut when used for vacuum purposes.

 

I used the correct gauge and type of hose...with regards to the rod? I have to ask my mechanic...cuz he installed it for me. I'll replace the brake pads too just in case. The set that I have has been in the car for close to 2 years...though I hardly drive the car except for autocrossing....and joy rides
