rear disc conversion 71 c10 e-brake

A very good amount of explanations about rear disc conversion for a 71 c10. Some have broken links or prices that may have changed. An emergency brake may not be required but if you don't quite trust your trans linkage to hold can a line lock be used when a vehicle is parked. I don't plan on doing burn-outs but can a line lock be cost effective as a parking assist?

Talking Re: rear disc conversion 71 c10 e-brake

I bought Captainfab's Pre-LS1 Camaro/Firebird rear disc brake adapter set and it has the provision for an E brake, but you need the '93 to '97 setup,as the 98 or later use a drum/shoe that is integral of the disc rotor.
Captain Fabs setup uses caprice rear rotors and this setup works great! In order to make the rear E brake cables reach, I simply moved them in board of the frame.
Hope this helps!

The only pieces that I had to use was adapter fittings for the metric caliper brake hose to inverted flare type and I took the brake hose mounting brackets off the Camaro I got the calipers off of and used stainless hose clamps to mount them to the axle tubes. Captainfabs kit has all the mounting hardware included.

Re: rear disc conversion 71 c10 e-brake

I really appreciate that you have helped me sort out which brackets to use. Please correct me if I am wrong.
Camaro calipers have provision for e-brake

Use? GOOD/BETTER/BEST?
Camaro Rotor
Astro van front rotors/year?
Impala Rotors/year?

Talking Re: rear disc conversion 71 c10 e-brake

If I recall correctly, you have to use the Caprice rear disc rotors. One thing to remember about these rotors, and I found this out myself, the center axle hub register(center of the axle that centers inside the rotor as well as the wheel)
Is about .045" to .050" to large to fit the rotors. You need to have this clearance in order to have the rotor fit flush to the axle. You need to have a machine shop take off .045"-.050" off the inside bore of the rotors center bore.

Captain Fab is a vendor here on the forum, most all the info you would need is right there. Make sure you get the pre-LS1 rear calipers! The LS1 type doesn't have the integral E brake cable arms, they use a shoe type E brake that won't work.
The factory Camaro/Firebird rear disc e brake cables work. But you have to route the factory intermediate brake cable in board of the chassis, there are two holes
one on each side of the drive shaft hoop of the crossmember. You run both ends of the factory cable through these holes and the Camaro cables will link up with the factory cable without extending the intermediate cable.
I used the brake hoses that came off the donor Camaro which are metric, but you can get metric to inverted flare adapters to join the hoses to hard lines.

Here is the link to Captain Fabs Camaro brackets.....

http://www.67-72chevytrucks.com/vboa...d.php?t=382633

At first I used the factory equalization valve for disc front/drum rears, didn't have any braking problems at all, but I changed to a disc /disc valve later.
I'm very happy with how it stops, CaptainFab's brackets did the trick!
Have a good one!
Ben

Thanks, sorry for being slow on the intake of info. 75 years young don't help much, but the more I learn the less I have to turn a wrench...Why should I reinvent something....Google is my friend as well as YouTube and glad to add this group.....thanks again.

Re: rear disc conversion 71 c10 e-brake

Trying to find info and put it here to have a quick reference on complete conversion. So far excellent reference. I plan on using the Camaro calipers.

Now what is entailed in pulling the axles to mount backing plates?
I know I could go look on the truck but I live alone and don't want to pull a wheel need to hire some help. I am gathering info and parts which may take a while with the holiday season in a month.
Hopefully this question is my last on this issue. Thanks to snipecastle2 and Captainfab,

Re: rear disc conversion 71 c10 e-brake

Congrats on being 75 years young and still be eager to work on your truck...

Check out this youtube video link...it will gove you an idea on what is needed to remove the axle...

https://www.youtube.com/watch?v=P80vg9eBouQ

It shows a later model but the theory is still the same...

Seriously,,,this is heavy work...suggest you gather the parts and hire some help to do the tough stuff...

Good luck young man...

Re: rear disc conversion 71 c10 e-brake

snipescastle2,

Sorry to drag up an old thread...This is all great information! I found the CaptainFab brackets recently and all of the great reviews. Your added information on the parking brake cables and proportioning/equalization valve is very helpful.

Question for you regarding the proportioning valve change: What master cylinder/booster setup are you running? Mine has front disc/rear drum and NO booster. Can I still run that setup by changing the proportioning valve?
