Has anyone used the disc brake conversion kit from the filling station 49BK-6 (47-59 PU 6 lug kit). I'm trying to convert my 46 1/2t. It looks just like a CPP kit, which many people have spoken about, but you never know. The price is better, even with the bearing kit. Just no option for a new set of hubs. And CPP is at minimal staff due to the California state quarantines, as a few others have stopped shipping completely. So I am hoping i can get parts out of Oregon.
Any info, or other suggestions is always appreciated.

You might find that many of the disk brake kits sold by the “catalog stores” are drop shipped from a group of suppliers. Many mention this drop shipping in their description With an expanded delivery time and add shipping charge.
That number of suppliers might be relatively small ?????????
Turns out the filing station kit IS a CPP kit. Right from the guys at TFS. Now the next question in my search is what have you all done to get the CPP kits to fit OEM 16" rims. My rims are from early to mid 50's 6 lug. What did you grind, move, adjust, ect. The CPP site says kit WILL NOT work on stock rims, however, many posts beg to differ.

I used a Performance Online kit on my '46, it looks the same in pictures as the CPP kit. With the stock 1946 16" rims I had to use the supplied spacers and grind 1/16" off the high spot on the calipers.
The rim clearance is usually just 15” that have a problem. 16” with 0 offset rarely have a problem.
The rear transmission cross member discussion is also often mentioned as a concern. Many of the trucks it’s already missing. Several posts on the merits of the crossmember. Depends on type of trans. Some shop manuals even mention some models did not have the rear member.
Some kits mention the engine cross member needs to modified for master cylinder clearance. Others make no mention. Master clearance might be tight with an automatic transmission conversion.
will be running mid 50's 16" six lug. I am hoping for, at worst, a little wheel trimming and a little caliper trimming to get a proper clearance. i have the rims, just not at my location. Getting them at the current time is not going to be a simple ride unfortunately. but, as showkey was saying, I have read on several posts the dilemma with a dual reservoir MC. Most folks say you have to engineer your own bracket and a little bit of relocation, especially with an original trans set up. I believe I have an original rear set up, starting to investigate that now, so i am between a T5 swap with original rear or leave the trans and swap the rear for a 3.55 ring and pinion. May come down to budget.

Another data point ........here’s a ‘50 GMC 1/2t with 4 speed torque tube and the dual power master cylinder mounted to the factory brackets. Ran for several years with no rear cross member. Pic shows partial install of an aftermarket cross member. Done as project not to solve any issues.

Hi Steve,
I'm looking for a conversion kit for my '46 3/4 ton flatbed. It's the heavy duty version with 8 lug wheels. I went to the Performance Online site and don't see anything there for '46 trucks. All they have on their site is the usual '47 - '55 trucks like everyone else. Do you have a special code that gets into the secret pre '47 section of the site?
The front axel and steering knuckles are the same on the Art Deco and Advanced Design trucks so the rotor and caliper swap is the same. The master cylinder location and pedal setup is completely different on the two trucks so you have to figure that out yourself. I had it easy because my truck is a 1/2 ton and plenty of kits are available. I'm not familiar with the 3/4 ton braking system so I can't help you there. I know the 3/4 ton stuff is hard to find so you might not be able to source a kit for your truck.

The Booster/Master Cylinder setup I've found is supposed to be for the '47 and newer trucks. It comes with a big bracket and pedal component that fits under the dash of the '47 trucks. The big benefit is not having to reinforce the firewall to take the pressure of stepping on the brake pedal. I'm not sure how different the dash is on the '47 and newer trucks but the company that makes the system is just a few miles from me and said I could buy it and if there is no way to make it fit under the dash I could return it, so I thought I'd give it a try since I'm having no luck finding anything specifically made for a '46.
