Installing new brake lines. front and rear calipers 68-72 A-body

In this video, I am installing new brake lines on my GTO. I show you how I install and bend my new brake lines. I am using S.U.R.R. for my brake line kit it is very easy to bend. Nickel, Copper material . if you have any questions or comments please let me know.

Great video, Thanks for sharing. Just FYI, On your 1/8-27 NPT fittings for the caliper the "NPT" stands for National Pipe Thread and they are tapered threads. The other end that your flex line attaches to is a -3 AN fitting and has a 3/8-24 standard straight thread for 3/16" tube and -4 AN fitting is a 7/16-20 standard straight thread for 1/4" tube. The AN stands for ARMY/NAVY which is a military aerospace fitting with a 37 degree angle for the sealing surface, It is used in aircraft and now in hot rod applications. Just a little info someone might want to know.

[@classicrewind2715]

Thanks Bob. I knew NPT stands for National Pipe Thread. I did not know about the Army Navy, AN threads. Great information. Thanks again. keep in touch my friend..

[@benodell9675]

Looks great love the blue frame.

[@classicrewind2715]

Thanks, I'm going to paint the car a similar color so it will blend together.

[@s2000blur]

I know the vid is 2 yrs old but you wanna set your line depth with op.0. This sets the blocks as well as the line. Then tighten your top clamp and proced with op.1 and op.2.

[@classicrewind2715]

Yes, that's good information. Thanks for commenting, All the best.

[@jmiguel250r]

I don’t think your supposed to put thread tape on flare fittings, only NPT fittings... npt fittings seal at the threads, flare fittings seal at the flare, fluid shouldn’t be getting to the threads

[@classicrewind2715]

Yes. you are right. The flare is supposed to seal the connection. I installed the fitting on the caliper 1/8-27 (National Pipe Thread) NPT. I want to make sure it properly sealed. So as a added precaution, I used thread tape everywhere. Thanks watching the video I hope you enjoyed it. All the best.

[@jmiguel250r]

Classic Rewind I’m not bashing you I appreciate your whole build been watching the whole thing, but I don’t know why willwood decided to use npt threads on the calipers, a banjo fitting would be safer in my opinion, I would think with the leverage from that elbow and constant movement and vibration from turning and suspension travel might loosen that fitting up

[@classicrewind2715]

I understand. I appreciate you watching my build and thank you.. The issue that I have with the Wilwood caliper is. They purposely make that 27 thread. I search the internet and I cannot find anyone that sells that fitting. So you have to buy it through Wilwood only. When I was screwing that part into the caliper it did not feel like a smooth seat, so I used thread tape. I used 14 inch flex lines in the rear and in the front calipers. I hope this explains it a little better. Again thank you so much for watching my video and following my build!! All the best my friend

[@bigdaddy5189]

Great video, You called the brake line 1/4 inch when stretched it the back of the car. But it’s 3/16 copper nickel, right?

[@classicrewind2715]

I think you are right. It's been so long since I made the video I can't remember. I would have to go and check what I did. I know in the back it gets reduced at the rear axle axle at the splitter.. all the best

[@classicrewind2715]

Thanks for the kind words. The 1/4 lines go from the junction box to the rear and then they break off and become 3/16. It's explained in detail if you watch the whole video. All the best .

[@jimmymaggs3371]

No problem. I sometimes confuse the lines as well. it is easy to do in these old cars. All the best my friend.

I'm glad you enjoyed the video. No, I did not do the gas lines yet. I am still working on the body. How far along are you with your build? All the best

[@cbrSpeedster1]

Is the distribution manifold still needed when using the wilwood master cylinder with the proportioning valve? Thanks

[@classicrewind2715]

It's funny you ask that question. Every time I do a build that question comes up. Wilwood recommends it because it's disc brakes all the way around and the original proportioning valve is set up for drum brakes. Unless the proportioning valve is set up for disc brakes. There is a lot of questions regarding that setup. when I build the GTO, I am going to eliminate the proportioning valve and I am going to put a adjustable proportioning valve near the master cylinder. I hope this helps. All the best

[@cbrSpeedster1]

@@classicrewind2715 I went back and looked at other comments regarding distribution block.. like you said the proportioning valve takes care of front and rear disc's without the distribution block. I'll look forward to that video. I have the Wilwood brakes systems ordered but not ready to install yet. Thanks for the info and videos

[@hankfink]

Do you feel ok about NiCop lines without any gravel guards in the rear axle or engine bay? Seems like cheap insurance since the lines are pretty soft. Nice to work with though!

[@classicrewind2715]

That is a good question. I found that gravel guards hold dirt and moisture which corrodes the lines. My GMC truck, I've replaced all of my lines that had gravel guards because of that reason alone. Since this car is not going to see any dirt I should be fine. All the best

[@robert9113]

Can you please tell me where to find a 68 cougar disc brake line diagram please

[@classicrewind2715]

I would look online. I'm pretty sure it is similar to the Chevelle. In line tube has a brake diagram that might be able to help you.

[@waynebauer2770]

Looks great Harry, couple of questions. I see your distribution block is down on frame, mine is relocated to the firewall under master cylinder. Also, I noticed in video you have ratchet straps around rear. Did you use them to compress rear springs to ride height? If so, did you then tighten rear control arm bolts. My Chevelle says this dimension should be 5 inches from top of axle to bottom of frame. Thanks

[@classicrewind2715]

Hi Wayne. No, my distribution box is on the frame that's where it was before I removed it. It is also like that on my Chevelle. I don't know why yours is under the master cylinder. For the ratchet straps. I just used them so I could lift the rear and attach it to the frame without jacks. I suspended it from the ceiling in my shop. I adjusted the rear to the frame before I tightened all the bolts. I hope this helps all the best

[@waynebauer2770]

@@classicrewind2715 my distribution block was on frame , like yours. When car was set up for manual drum brakes all around. My front disc conversion kit moves it up. I was just curious about yours. Are you going with power disc brakes. Was car originally front disc? Thanks

[@classicrewind2715]

No, The GTO was drum brakes all the way around. I put in disc brake conversion kit from Wilwood. I'm going to make them power brakes

[@jasoncroft4822]

Did wilwood recommend 1/4” for the main line running to the back ?

[@classicrewind2715]

No, The distribution block is set up that way. 1/4 " to the rear, 3/8" to the front. Then 3/8 from the splitter to the rear brakes. I hope this helps. All the best

[@arn_thegreat]

Great video. Did u have to make custom brake lines because of the aftermarket box in kit? U couldn’t buy a new original brake lines?

[@classicrewind2715]

That is correct , I had to make my own. I could not use the original brake lines because I used the frame boxing kit. I also used a Ford 9-inch rear, converted the brakes too disc brakes. I had to make my own lines. I hope you're enjoying the videos. All the best

[@arn_thegreat]

Classic Rewind Nice!! 👌🏼 good to know bro im doing a similar build but a Chevelle. Same box in kit tho. Great videos keep them coming.

[@classicrewind2715]

Awesome. But be careful you need to watch the video. I show you a bunch of tricks to make sure it doesn't hit your floor pan. In the back of your knockout plugs it will hit no matter what you do, unless the frame kit is about a half inch lower than your frame.(in the rear)You will have to flatten out your knockout plugs. If you do not lower it passed your frame rail. All the best my friend

[@pete_zorb2214]

What was the part number for the rear flex lines? Or was it the same as the front? Thanks

[@classicrewind2715]

The flex line is the factory original, you can purchase anywhere. I just modified the bracket. I am using a Ford 9-in rear

[@pete_zorb2214]

I meant the stainless flex lines from rear caliper to hard lines

[@classicrewind2715]

@pete_zorb2214 The lines were the same as the front. The thread count is the same. The only thing that is different is where it goes into the caliper. You have to make sure to get that adapter. I'm sure it comes with the kit. I hope this explains it all. Any more questions, let me know. Glad to help. All the best

[@christiansaco8998]

Hi I have a stock 68 cutlass supreme and I’m having trouble finding a proportioning brake valve for it and I’m looking everywhere do you know anything about them?

[@classicrewind2715]

Hi, look up brake distribution block for 68 Cutlass. If you are using original stock drum brakes you should not have a problem , all the parts stores should have them. Napa , AutoZone if you're looking for a proportioning valve for disc brakes that might be a little more difficult. Only certain cars had disc front drum rear brakes. My 68 SS Chevelle has disk brakes the proportioning valve is the same as my GTO that was all drum front and rear. I hope this helps. All the best

[@christiansaco8998]

@@classicrewind2715 ya it’s drums all around but for some reason the shops didn’t have them and I’ve already ordered a valve and it didn’t fit and I’m having a hard time finding the right one

[@classicrewind2715]

@@christiansaco8998 They might have given you the wrong one. Does it look similar to your old one ? If not you might want to consider doing your own brake lines connectors to your new proportioning valve. Napa has sections of brake line you can buy. Just make sure they fit your connector. Sometimes the new valves are metric thread .you need to be aware of that.

[@ubethejudge69]

Very nice job. great looking frame as well. Hey quick question, do you know if the distribution block can fail? Also with the Willwood's did you still run the hold off valve so the front brake's don't activate right off the bat?

[@classicrewind2715]

Thanks for the kind words. That is a good question. When I spoke to Wildwood , they recommend me putting a portioning valve. I am running hydroboost in the GTO. When I spoke to the person I buy my parts from he told me, I did not need to change the distribution box. I also spoke to a couple car builders that I know and they also recommend me removing the distribution box and replacing it with a proportioning valve. I hope this helps. All the best

@@classicrewind2715 Cool thanks for getting back to me. have a great day

[@thetruth257]

Awesome video, just one question, is that the original distribution box that you are using?

[@classicrewind2715]

That is a good question. I've done some research. I cannot use that distribution box, Because I went all disc brakes. If I use that distribution box there's going to be 2 lb of pressure on the rear brakes which will cause it to lock up prematurely. I will have to get a proportioning valve. Therefore I am going to purchase a new hydraulic booster with proportioning valve. I will be making a video of that when I'm at that point. All the Best.

[@classicrewind2715]

Sweet ! LeMans. I was thinking of stripping the frame myself that is a lot of work. So I was looking around and I got it powder-coated in instead. They actually sandblasted first. Then they bake the paint on. If you decide to powder coat it make sure you do all your welding before you take it to them. You might want to consider Raptor coat, Very durable and you tint it certain colors. All the best

[@andrer3854]

How much welding setting adjustment needed to weld sheetmetal vs frame boxing.

[@classicrewind2715]

That would not recommend using sheet metal when doing your frame. They make good kit that you can weld to your frame. Every machine is different. I would use 1/8 or 3/16 Steel. Check out this video. I think it will help. All the best kzbin.info/www/bejne/aaGQmohjrLaEsJo

Wilwood specifies 3/16" lines not 1/4"

[@classicrewind2715]

It's 3/16" the front rotors from the distribution block. 1/4 " from the distribution block to the rear splitter, from that splitter it becomes 3/16. If there's other literature that I missed from Wilwood. Please send link. I will be interested in seeing it. All the best
