C20 Disc Brake Swap Guide (Part 1)

[@jamesharlanjohnson6882]

Performance Online has a complete set for C20 8lug conversion from drum to disc and 2.5" spindle drop. I just completed the conversion this weekend, Due to supply chain issues from the forge in China it did take 7 months for delivery of the knuckle/spindle!

That is great information, it’s crazy how fast new stuff is coming out. Hopefully within the next few years they will also make full repro cabs on the 60-66 styles. Thank you for sharing.

I had the opportunity to grab an entire factory power brake system on a 67-72 truck a fellow was scrapping many years ago but did not want to have to pull it down and have to store it till I was ready to do the work. When I was ready in the summer of 2017 I bought a complete upgrade pkg from CPP at a price of $5000.00. I gaurantee the factory parts would have been a fraction of that price, and the fit would have been much better as well. Best days to you 👍

I just purchased a 1966 C20 and I intend on only converting the front drums to discs and keeping the 8-bolt lug pattern. Western Chassis seems to have a conversion kit ready with all the parts necessary.

[@MAYCOCustomRestorations]

That’s great they are getting kits on the market for the c20s. Thanks for the info. Will you be ordering that kit? if so let us know how the install goes!

Do you know what power steering gear box would work with a 67 truck?

[@MAYCOCustomRestorations]

If you call redhead they will tell you. That’s where I got my steering gear from after messing with two I pulled and tried ordering rebuild kits was a total pain/failure.

[@davidchlup8162]

How does the break hose go through the frame? My drums were routed on the other side. Is there a bracket or fitting? Thanks for your videos!!👍

[@MAYCOCustomRestorations]

I cover that information at about the 8 minute mark and the part number is in the description as mentioned. If you want to see more pictures and info on the routing I had a thread on it on the 67-72chevytruck forms: 67-72chevytrucks.com/vboard/showthread.php?t=832601

@@MAYCOCustomRestorations thank you

[@MAYCOCustomRestorations]

No problem, glad it helps- thank you for your support

I just bought a c20 And need that info on a 8lug to 6 lug swap

[@MAYCOCustomRestorations]

Ive seen threads on the forums regarding that over the years. Id imagine it would be as simple as swapping spindles/balljoints/maybe outer tie rods on front and hubs on rear depending on the rear end. Not 100% sure.

[@davidchlup8162]

What proportioning valve did you use?

[@MAYCOCustomRestorations]

Sorry I haven’t gotten to that yet. Will post a video when I get there.
