Technical 54 Chevy truck brake upgrade question.

So I have a 54 Chevy truck with 3 speed manual transmission. Shift is on the column. I want to upgrade the brakes was going to put disc brakes on the front and keep the rear drum brakes. I was looking at the double pot master cylinder with boosters that mount in the factory position and all I've seen say automatic transmission only. Is there a kit that works with the 3 speed manual transmission?

 

Gotta remember most old vehicles the clutch pedal mounts to the master cylinder.... especially old Chevys. So you'd have to get a separate pedal for the clutch and run hydraulic clutch.

 

Here is what I did on a 47 Chev pickup, I would think it is close to the same. IIRC it's a 70's AMC master, drum on drum. Worked just fine with stock brakes.

 

Nice! Clear pictures, full description and quick, too.
Hope this helps OP (with his disc difference), but if it's different, it should help someone.

 

Colum shift linkage is the issue for the booster
Floor shift?
Hmmmmmm

 

`

no, the kit he is looking at has one of those ugly firewall mount boosters and no provisions for a clutch pedal
What BRJ showed in post 3 is totally irrelevant as the truck he did it on was a DECCO truck rather than an Advance design truck. That being an early 47 rather than a late 47.

A lot of vendors sell this setup that bolts to the frame and on this one the bracket I have the arrow drawn to bolts to where the original master cylinder did on the stock bracket. It's pick your favorite vendor or the unit that folks say is the most reliable or least h***les. This one should be a nice low h***le install It also has a real beefy push rod that you need. You don't even have to unhook the clutch linkage or shift linkage to install it.
The second photo is the bracket, pedal ***embly and old crusty master cylinder that I saved off a truck I s****ped out.

Third photo just points out the bolts you have to remove and the clevis you have to undo.
You will also need the correct residual valves for front and rear to maintain a little pressure in the lines to keep the seal on the caliper and the cups in the wheel cylinders tight in the bores.

 

a little more dear than the junkyard!
