Firewall mount brake booster on 52 truck

Well here I is again! I need further input. I have a 1952 chevy 1/2 ton. I am converting to front disc brakes. I currently have the brake booster that mounts in the factory location. Basically It appears to be a real inconvenience in the long run. So my question, has anyone performed the booster conversion that mounts on the firewall? If so, I would really like your insight on installation. I'm debating doing this as opposed to the factory location. Is the brake pedal any easier when driving. Is there any major modification needed or is it pretty straight forward? Will this work with the stock inline 6 with one carb?

Help

I'm going to give you my opinion and I hope you don't take offense.

You have already bought the under floor set-up and are having trouble getting it installed. So you figure the easy way out is to spend more money on another system that is not going to be a bolt and go deal. You are going to have to overcome problems with that too.

You'll never finish the truck with that approach. Throwing more money at it isn't going to fix your problem. You need to jump in there and do what it takes to get it fixed.

I sent you a link to a site detailing the problems I had and how I solved them. That should get you started.

Cletis-
I appreciate your honestly. As far as the money goes, the company I purchased the kit from said they would switch units with me at no additional cost. My concerns were more regarding serviceability and accessibility. Although I do take fault in not doing my do diligence prior to ordering my kit, this is my first conversion. My experience with modification is minimal hence the reason I am trying to gain insight from fellow truck owners.

Guys,
I was planning the same swap (stock location) and I was not aware of any issues. Could you please explain??
Thanks, Bob.

I like my firewall mount. Wasn't painful to install as I recall, and no significant issues. The bracing is stout so no firewall cracking at 8 years and 66500 miles. :

Nospark-
well it depends on what u have. Mine is Totally stock 52 chevy 3100. Inline 6. 4speed manual....the booster hits the transmission rear cross member support, which means you will need a new cross member which you can get. You will need to drill 3 additional holes in the frame for the bracket. You will also need to "tweak" one of the bracket arms which hits the forward transmission support. The brake master does not sit under the factory fill hole. It sits more under the gas tank. So serviceability is not easy.

Chuckthetruck-
I take it you still have the L6 engine? Single or dual carb? I'm concerned about enough room. Also with the new brake pedal, does it make it any easier to apply the brake and/or put the truck in reverse?

Thanks the the posts guys. Hope to talk soon

Any modification you make on these trucks or any other vehicle requires overcoming problems. There is no such thing as a bolt in, trouble free replacement. Even most of the "stock" aftermarket parts don't fit right. If it were easy, girls could do it.

Sits above the manifolds on my 250. Pedal is comfortable - I don't recall what original felt like.

Chuckthetruck- thanks for the help. I appreciate. It seems to me the firewall mount makes more sense. Serviceability is better. Easy to access not to mention running brake lines might be easier as well. The factory pedal come out really high. It makes it a little tough to put the truck in reverse hence the reason I was asking about ergonomics. Looks like you did a great job with your truck!
