1970 c20 disc brake swap
I am thinking of installing the disc brake swap on my c20. I have gotten estimates from shops that want 2000 to 3000 grand to do it for me. Now my question is: is this truely a bolt on kit? No welding, no fabrication, no rocket science?
I am not a trained and experienced mechanic. I have never done more than oil changes, brake pads, tune ups, etc. Can this be installed by someone without a lot of experience with front end work? Or should I bite the bullet open my wallet and let an expert do the work? please advise, paul |

Re: 1970 c20 disc brake swap
Don't know the year of your truck but the 72 is stock with disks, just replace your parts with stock 72 parts and it may be cheaper, get a disk proportining valve from inline tube.
Probably a lot of people here have done this so try the search feature and see if you can find write ups on it.

Re: 1970 c20 disc brake swap
swamp, according to the thread title it's a 1970.
Paul, it is bolt on. You will probably have to bench bleed the master, bleed brakes, and have an alignment done, but you can figure the first two out and pay someone to align it.

I sent an email to the supplier asking to see the detailed install instructions and they have never responded. That does not increase my confidence in the supplier or the simplicity of doing the install. Ill try a phone call. I looked at a lot of threads on the forum. None of them gave detailed instructions on how to install the swap I.e. first do this, second do this, now remove this etc. thanks for the responses. |

Re: 1970 c20 disc brake swap
It's easy to install, but it is very important that it's done correctly. You don't wanna be unsure when it comes to brakes. Maybe have someone that has experience help make sure it's done right

I could not agree more! Where to find said person is the problem. You dont find to many brakes experts just hanging around waiting to be asked to help.

Re: 1970 c20 disc brake swap
Any special tools needed you should be able to rent stour local auto parts store. Ball joints can be tricky to press in if you've never done it, but a YouTube video would probably give you enough knowledge to do it.

Re: 1970 c20 disc brake swap
ball joints are a nightmare to remove from the a-arms. make sure you leave yourself a lot of time. also they are usually rivetted in so unless they have been replaced before youll need to have some kind of grinder to remove the rivets.
The rest of the work isnt technical or difficult. The only thing to pay attention to is the wheel bearings and torque on the wheel nuts. |

Re: 1970 c20 disc brake swap
If you have the time, patience, and a BFH you can do this. A pickle fork is sometimes handy as well as a floor jack. Keep researching on this site and Im sure you will find someone that has documented this swap. You might also want to replace your control arm bushings at the same time. Whenever I do a disk brake swap I replace any other items with wear also. Have you considered sourcing your parts from a newer donor that has discs already? You could have the rotors turned but buy new calipers,ball joints,hoses, and master cylinder. Inspect the spindles and booster and revive with some Krylon. If you dont already have a front sway bar grab that too. They make a huge difference. Just take your time gathering parts,clean and paint any old parts, and do lots of research. You will save plenty of cash and feel good too.

Re: 1970 c20 disc brake swap
its pretty simple if you find the swap threads, take their advice, and be relaxed and thoughtful when you proceed,
Just did mine and it worked well, one month of testing and I was out with the yotas and jeeps rock crawling without too many issues, once I lost brakes because my remanned master is bad. that's the worst part, new is pricey as you see. remanufactured is a gamble, |

Re: 1970 c20 disc brake swap
It is not a difficult swap, and if the member in NV cannot help you out...I have a 71 or 72 that would be a direct swap for you also..

Re: 1970 c20 disc brake swap
If someone is parting out a C20 truck go the easy route. Unbolt the entire crossmember and roll it out. Take the whole darn thing. 2 brake lines (cut those) 2 shock upper bolts, and about 12 or 14 large easy to work with bolts and roll it out. You could even bolt it as is into your truck. I would rebiuld/ replace wear items, but you could just go with it. And best of all, EVERYTHING will be stock!

Re: 1970 c20 disc brake swap
I've been searching craiglist for a while and saw an add that mentioned 3/4 axles. that's my supplier
The guy bought them for a build then wanted to go one ton and lucky for me didn't know what he had except they were from a 73 heavy 3/4. The front had stock discs and I took everything from the knuckle oout, spindle, hub, disc brake bracket, rotors and calipers. it all slid onto my d44 5cf without mods, or much effort aside from the obvious. be sure to check bearings and seal. best tip is learn what to look for from the forums, try to match your axle, and don't take what they say on craigslist too serious. they may think its one thing, but then you look at it and its something different. I got both front and rear for 300, and my mechanic would buy just the rear for 500 ![]() |
