well I have been getting some steady time out on Wilma. alot of it has been ordering and organiing parts and and supplies that I didn't have or needed.
I knew building a completely new brake system would be a challenge, though I did not realize the physical building of it would be as easy as its been. and the hard part being getting all the correct parts. I have gotten doubles of some parts and some parts that I didn't even need.. I have bent up a new hard line that runs along the frame to the rear set up tried to attach it to the finished rear section and found the new braided flex line from the frame to the axle was 4" too short
its been a bunch of stuff like that, along the road but its coming together now. I have leearned how to bend new brake lhard-line and add a flare to the end. I ordered my 2lb resistence inline peice and a proportioning valve for the rear setup and should have everything finally by early next week.will be nice to cross something so huge in the project off the to do list.
I will try to give an acurate account of what went into the set-up and where i got it. I'll start with the rdb setup
-rear chevy rotors and caliper brackets. " Poser" on Mud, nice stuff
-rear chevy calipers and braided flex lines, TSM nice stuff prolly should have gotten the lines from Classic tube but more on that later.
- T fitting and flex line from axle to frame. Classic tube made me the exact length I wanted and put a female 10mm end on one side and a female T fitting ont he other. very cool but I wish I had known the female T was possible because I tracked down axle T's from later model fj40's in that I thought they were an unobtainium new part. silly me.
-New hardline on frame from rear axle to front frame junction. I got 10mm fittings a flare tool and 25 feet of hard line from classic tube. i have since ordered another 25' of tube in that I want to use les braided flex line and more tube to keep the brakes fresher and solid.
- the junction on the frame that sits right below the firewall. I got this from a part out 78' fj40 rig and will be the only 'old' part used.
-the 2 hard lines from the junction to the MC will be made new but I bought some used ones from cruiser parts as guides. they are from a late 70's fj40 and while they would not hook up to my MC they do follow the path to the junction on the firewall and will be an excellent guide.
-the front brakes I will use the exsisting disks or a spare set of fj62 disks that I have if they will fit . I have not looked into it.
- there will be a short hard line off the frame junction forward to where I can drop the flex line straight down to the axle.
-a T to 2 flex lines that will got to the calipers.
- I am using the 4 runner early 90's v6 calipers that have the 4 big pistons
-I am using the late 70's firewal which I clear as mud document the installation of. inorder to use an early 70's brake booster
-on the rear hard line from the MC I am using a 2 lb resistence from willwood that I got from Summit Racing along with a Manual proportioning vlave that I also got from summit. the 2 lb resistence will keep the pressure in the line for the rdb and the proportioning valve will help me dial in the correct fore aft braking for how ever i have the lv loaded.
-and finally I am using a 93 4runner brake master in that it has the wider bore ( I checked last night it fits on my booster which is a relief) hopefully this willstop my lv.
I had to redo every line in that the new hard lines are a bit wider diameter and all the modern fittings are 10mm not 9mm so I could not simply bite off alittle I had to bite off the whole thing. also the stock brake system was set up for 4wdrums just having the disks in the front was prolly over load enought. and boy was the stock system convoluted.
i will post some progress shots this week end
