TUrn your idle up 100rpm and stick a $50 summit vacuum can in with the brake booster. Mount it wherever it fits. Your brakes will come back.

Whats there to put a pic of? Buy a vacuum canister, hook it into the line, and screw it down anywhere. Simple.

Here you go.

Canister Location

The hose is connected on the passenger side instead of the driver side.

Not really, I have a guage inside my car that tells me how much reserve capacity that I have in the canister. Makes a good tool too have when I'm staging up to the line. If I don't give a quick rev before I stage I really won't have the holding power when I get on the stall.

The biggest problem is to find the proper routing of the vaccum lines. Once you get that sorted out it's down hill from there.

Yes, It should, It's strictly used for a reserve capacity. So with that said it will help out until the reserve capacity is used. Than it will need to be "filled backup", hince a quick rev should do it. Than repeat procedure.

Is this a daily driver or a weekend toy?
