Does anyone happen to have a quick photo or a sketch of how the stock lines on a 1952 gmc 3/4 ton are supposed to look directly after leaving the master cylinder. I have run all new lines and put in the new master cylinder. I would love to have how the master cylinder hooks up to the brake pedal, I have an idea on how it should look, as well as how the 2 lines hook up to the back of the master cylinder. My old system looked to be a "jimmy" rigged system, and i can do the same, however I would just rather do it right. I will post some pics this afternoon of my current system. I would like to be able to get some part numbers or a supplier of parts that I will need to hook up the brake lines. I assume I will need another "T" block as well as a small fitting of all thread or something like that. Any help would be greatly appreciated!!! bwolf
Surrrrrre~ Now you ask... Brian, first off, I PM'd you. I just pulled mine off two days ago! Next, I will get a picture of the brake lines held in place. Really though, it's no big deal. The line came out of the back of the master, bends around to where it goes to the back of the engine/transmission mount, turns and goes to the passenger side, hits a T-block, goes to the front and back. Hope this helps, but I will post pictures later.
Paul, I wonder if our brake lines are different. I will hopefully get a pic of my set up here by this afternoon or tomorrow. Well i tried to upload this image, but i can't. I will have to upload a pic later. Anyways I have 2 lines going to the master cylinder. One from only the Drivers side front and the other line from that t block on the frame, where it splits from there to feed the pass front and the rears.
Here's what I had~ I got you a picture of my single master cylinder and I tried to hold the line that went out of the back of it over to the passenger side where it splits. I laid the forward part of the lines on my frame so you could see how they went. I also included what happens when it gets to the back axle. Hope this helps. Paul The second picture shows the clip that holds the rod inside the master cylinder.
thanks paul!!! Looks like I have some work to figure out. I have my 2 lines coming to the master cylinder, not sure what size they are, but they are smaller then the 1 connection from my master cylinder. do you know of any places that would sell any type of divider block? What I am going to need to do is to find a connection that fits my master cylinder, a brand new one from our hosts, part no 71-207. Then I will need a small piece of brake line to a reducer, then to a t-block to then split off to the other lines. I just don't know what else to do. If anyone has some spare part that im missing, I would love to take it off your hands for you Thanks bw
Brake pedal connection From Paul's photos, the GM looks similar to the Chevy, so here's a couple shots of the brake pedal connection from my project, just in case it might help. Larry
Brian ; I didn't crawl under my truck to look but IIRC , there's a block on the back of the MC that's held on by a hard to find Banjo Bolt , Chevs Of The 40's used to sell this part , then a short steel line over to a " T " fitting on the frame . Some oldies I've worked on , had a " T " fitting attached to the back of the MC Did you ask Inline Tube if they sell this ? .
I have looked at chevy of the 40's and they don't seem to have the part I need. Paul has been kind enough to lend me his used parts!!! I don't know what I would do without him Anyways here are a few pictures of my mc and the lines that I have going to it. I still need: the clevis to connect to the pedal Some sort of fitting to connect the 5/16" connection leaving the mc. "Cannot find anything. the connection is so deep in the mc that its hard to get a fitting that long." Looks like i maybe able to seal up to the outside part of the mc, not the inner fitting. I got some fittings off my old brake line system, it is the t-block that will connect the 2 lines to the mc, then I will use some fitting to take the 2 smaller brake lines to the larger 5/16" deep connection to the mc. Here are some pics of what I'm looking at!!! Enjoy Larry and Nate thanks for the help also. I really appreciate all that everybody does for this site. its nice to have a place to go for help. It saves me from beating my head on the wall.... well too much
You're in luck! I'm putting in what you will in a year or two. A dual MC with discies up front and _drums_ out back. Since I have these spare parts laying around, and you remind me of ...me... I'll send you all that I took off. I have no idea why it won't work, and you won't have to do anything except buy a couple of length pipes that are already "fitted" at the ends. All you need to do is bend them, and that works pretty well using a box end wrench. I'll cut my tubing (for shipping~ remember, I had a leak in a length of this that I didn't know about. They are old and unusable as is.) and mark the cut ends so you can lay them out and bend your new ones if you need new ones. Basically, it looks like yours does the same as mine did if you look at the photos I posted of my brake line routing. Glad to help! My brother Ken and Bill Hanlon are inspirations to me as far as parts and that goes. We are here to help!
Master Cylinder Fitting Yep , it seals against the back of the master via the annealed copper washer... Did you ever goo look at Vintage Chevrolet ? they use old parts diagrams that are*very* helpful . Or maybe the old car manual online project.... another wonderous website .
Thanks again fellas!!! Im excited to know that it will at least seal against the back of the mc. I was worried that it wouldn't. Now if i can find me that clevis connector for the front, I will be in great shape! Thanks nate for those links.. they have a ton of info!!! paul, thanks again for all the help, man you rule I sent you a PM
Try This : http://chevy.oldcarmanualproject.com/1929_54chevyparts/04/293.HTM This should take you directly to the Huck brakes master cylnder page with illustration on top and all part numbers below... Sorry the illustration sux so badly (it's a cutaway) but you can clearly see the Banjo Bolt and fitting ... On the bottom of the page are colored links , book mark it and then spend some time poking around , they have simply KILLER pictures of Huck brakes for both 1/2 ton and Big 'Bolts too.....
thanks... I did bookmark that page, i will spend some time browsing around there to see all that information. thanks again for all the help and support, i definitly cant do this alone!!!
