Re: HOW TO: Split the brake lines (many have asked)

dug this one up cause I really want to do this. Question though, can I just buy new pre-bent lines from the Truck shop and make it a full on bolt in affair? I dont mind spending the extra cash since I dont have the time/space to fab up the lines myself.

Re: HOW TO: Split the brake lines (many have asked)

the lines are real easy to bend, in fact, if just keeping the 4 whl drums, you don't even need to cut and flare the lines if you buy the right lengths, see my posts on this and it probably gives you the lengths I used. When doing discs up front, you will need a lot more plumbing for the prop valve and all.

1) No holes need to be drilled...it'll bolt right up.

2) The push rod had to be extended. I sold my black truck, and for some reason never got pics of the rod. I cut the stock rod in half, then welded more rod between the two. I still retained the adjuster part of the rod. Once the master is installed, and the pedal is in it's released position (check your bump stops too) you want the tip of the rod to be about 1/16" to 1/8" max away from the piston.

3) I purchased some straight pieces of line from my local fittings store (or a speed shop).....it came with ends. Bent them and double flared them myself.

On the '60-'62's you will need to drill holes to bolt up a '63 and newer master cylinder

Re: HOW TO: Split the brake lines (many have asked)

Has anyone done this, and have a parts list, and what modification the push rod needs (adjusted or welded) and length for the brake line?

If going from the 63 MC to a 67 C10 MC the bore diam is smaller 1-1/8 vs 1" from the numbers on line. IIRC this would require more peddle travel fro the same brake force?

Got my 1964 with a new master cylinder in the plastic bag on the seat not installed looks like he one you used.Is there a way to tell difference in drum/drum master and a drum/disk master? Is there a proportion valve for a drum/drum set up? Thank you

I have another question after reviewing, My old truck has the original master on and also has a power brake booster from a 84 C-10 on it. The power brakes seem to work OK but !!!?? The power brake rod was modified. All this has me confused I need your advice what direction do I go?

Re: HOW TO: Split the brake lines (many have asked)

Don't know if it's cool to bring this back up but I'm thinking that I really want to do this when I put my truck back together in a week or two. I get the concept with blocking off the one T and the split but where I'm lost is the push rod... anybody have clever ideas on how to make a good pushrod? Would a pushrod like this work? Any thoughts on where to get the parts it does?

Thanks!
Barry

Re: HOW TO: Split the brake lines (many have asked)

You can use your old master cylinder's push rod. If it is addjustable then addjust it out,if it is not you can have some one cut it and weld it. Or you can get an addustable one from speedway or a used one from the wreckers.
The push rod that is in the link will not work I used that type on my clutch master it had a pushrod with a threded end.

Re: HOW TO: Split the brake lines (many have asked)

Would the pushrod from a 67-70 non-power truck work for those who don't have an adjustable one? Just a thought...

you are not alone on that if it isnt one thing it is another. Hang in there

Back to the original post: my oe push rod was about 1/4 to short when fully addjusted due to the fact that I used an adapter for the master cylinder as a 60 used a 3 bolt set up and not 2. I ordered an addustable push rod from speedway it was 3/8 thred ,I used the part off of my old clutch master that attaches to the pedal, worked perfect !
Check to see if your push rod is addjustable it may work as is .

Re: HOW TO: Split the brake lines (many have asked)

Wonderful thread, ChiefRocka.....
As far as the tough times go.....I sure know how that works.
I'll bet it gets better.....Remember...
" Pain is just weakness leaving the body "
We should be pretty strong when all the crap blows over.
I thought I'd add a little info on my own brake upgrades.
A different twist....the K-1000......4X4 mods.
I swapped my stock frt. & rear diffs for late model Dana 44 & 12 bolt corp. respectively....
Because I wanted to add the Hydro-Boost set-up eventually, I used the down-time to take care of it all at once.
With the new disc brakes and larger rear wheel cyl.s, I thought it wise to add the brake proportioning valve along with new brake lines.
I didn't do near as good a job with the camera as you did, but I did take a few.
I hid the new valve inside the frame-rail just under the driver-side firewall, and split the lines from there in the same order as you explained.
I also took the slide-on spring style tubing shield what-ya-call-its off of the doner 1-ton and used them coming off the master cyl and again in high abrasion or vibration areas like across the cross member, near the rear wheel cyls, etc. I slid them onto the line after the bend, before the fitting and flare work.
Here's the few pic's that show a little of what I did.
I could take a pic of the proportioning valve if anyone wants to see it.
As far as the twin master cylinder set-up that's stock for the '63....the clutch MC sure is a different story. More on that if you're interested on my build thread..."Rockdrillers '63 K1000".

After reviewing the photos, I can't say that I showed you much.
I'll take a few good shots of my work and post them a bit later, as I'm sure this thread will circulate around for some time, being the best reference for brake-line work that I've seen so far
Nice job, Chief.

Using a drum/drum master (two port Impala) you do not need a prop valve.

Chief or anyone - is there an easy way to tell a drum/drum master from a disk/drum by looking at it. I ordered a 67 C10 dual res mc from oreilly's - but there was no way of ordering a "drum/drum" vs "disk/drum". It just was what it was, only one option. (or did 67's not even have a disk brake option? - if no, then any mc ordered for a 67 would be drum/drum by default?)

Happy to show my lack of 67-72 knowledge in order to find an answer!
thanks.

Re: HOW TO: Split the brake lines (many have asked)

Disc/drum master has one bowl smaller than the other. Disc/disc and drum/drum both bowls are the same size.
And no disc brakes til '71
