The Stovebolt Site Forums The Shop Area Driveline brake booster on 41 firewall

I'm trying to lock down the parts I need to get my truck to stop.

It had a firewall mounted MC when I got it years ago, and I'm going back with that. But I would like to add a booster. I've had help here with MC selection. Thanks.

So, I'm talking to the vendor about a MC/booster combo (1 1/8" MC, 8" booster) and he said he wouldn't sell it to me because it says it's for 1/2 ton, and my truck is a 3/4 ton. He suggested I talk to their supplier, CPP, and if I got their OK, he would sell it to me.

So, I made a call to CPP, explained the situation, and he said he would research it and call me back. I finally spoke with him again, and he said they recommend a 9" booster.

I'm OK with that IF it will fit. Which brings me to my question. Anybody installed a 9" booster on the firewall of a 41-46?

I'm thinking I will need to get a smaller air cleaner (no biggie), but I'm more concerned about it interfering with the "V" brace rod.

As always, thanks for your advise.

The extra inch of booster diameter will add a considerable amount of stopping power (makes the driver's leg stronger) but consider this- - - -ANY BOOST AT ALL IS BETTER THAN NONE! The length and leverage of the pedal will probably have more of an effect on stopping power than the diameter of the booster.

Be absolutely sure you build a sturdy pedal pivot and angle brace it well- - - -the firewall is way too flimsy to anchor a pedal and master cylinder without lots of bracing.
