Boost leak at brake pedal

[JohnTSI]

After finally starting up the car for the first time Saturday and taking it out it was popping and missing under boost. Of course it was a boost leak, but I was suprised at where I found it. It is leaking in the car at the brake pedal. I assume the check valve for the brake booster is bad. I am not really looking for ward to putting another brake booster on so I will probably just put a check valve in line. Car runs great with your foot on the brake. Has anyone had this happen befor?

There are a couple Threads on this - Stock Check valve is INSIDE stock Vac hose - You can replace it by splicing in a generic Steel PCV type Check Valve. You'll have virtually NO BRAKES if booster is bad so be CAREFUL!

Ah I had the stock brake hose replaced when i put on the magnus on. I really dont recall seeing anything strange about the hose as far as having a valve in it. Thanks for the help though.

That's what I did - Thankfully I didn't throw the old hose away - You can feel the "lump" & cut out the old valve & carfully slide it into the new hose with a little lube - It's a fragile teeny little plastic bugger.

I had my Bumper to Bumper guy look up the Highest Amp Mitsu Alternator that would fit a 1G:

- Max amperage 121 amps

- 100 amps at 3000rpm

- Max 1548 watts

- Manufacturer Ampere - Ampere P/N 21491

- Cost was about $150.00

- I run a 1 Farad Cap too with an El-Cheapo Battery that pushes a 500 Watt Sony Amp & head Unit no problems - no dimming, etc.

I put it on Car Ramps & come from underneath so no need to remove Fan - It's still a PITA...

Make sure you have NO Power Steering Fluid leaks dripping on your Alt - that will kill the Voltage Regulator in a Heartbeat & can toast your ECU...

Car has no power steering and only runs 2 slim fans on the front of the fluidyne. If anything is gonna interfear its gonne be that dam 3" o2 housing.

Damn John thats one hell of a place. Glad you found it though. I personally have never heard of a leak there before. Oh btw..I still have that intercooler here.
