Disc brake conversion

[BIGRAM]

I'd like to convert my Dana 70 to disc brakes. Other than the EGR kit, is there anything more affordable?

Whats a EGR kit do?

I've put disc brakes on toyota's
a 87 chevy daily driver...14 bolt
and currently my 01 Dodge daily driver
it has a 70
did change to a larger master cylinder on the Dodge
thats it

[BIGRAM]

What parts would I need to locate for the swap?

EGR Performance Brakes sell a conversion kit for like $900.

Take a look at blackbirdcustomtrucks.com

That's a little better.

What are thoughts of a single rotor/caliper at the rear yoke. Good / Bad ?

[Hope Springs Hauler]

I think that it would get smashed on a traditional pinion. It works on Rocks 'cause of the topload design

[BIGRAM]

I thought that may be the case.

Thanks for the input.

don't buy a kit... buy some weld on/bolt on brackets, get you some rotors and calipers and away you go. the peeps that sell the kits are just doing the legwork for you, and charging you a few hundred bucks for their time. Source the parts and get it done.

I agree with Carwash. I bought my brackets from Great Lakes Off Road and they worked out nice.

Here is a write-up from on the Dana 70 conversion on Off-Road.com. They used 77 K20 rotors and calibers, but I was told by Great Lakes to ask for 1985 stuff.

have never spent more than 200 on any swap
get brackets and spend your money elsewhere

[BIGRAM]

That'll be my plan then. I haven't done it but I need to start somewhere.


That's a good piece of reading, So easy a caveman can do it!!

I was making a funny ;)

NAPA (or your favorite local autoparts, all pretty close in price)
1975 Chevy 2500/3500 loaded (w/hardware and pads) calipers - $42.99 ea. (after core exchange, they'll take any old core just dig some up!)
1975 Chevy 2500/3500 rotors - $37.99 ea.
Rubber hoses for calipers 12" w/hardware - $15 ea.
hardlines (hand formable) and brass "T" fitting - $20 total

Roughstuff Specialties
brackets w/bolts - $45 per pair (with Pirate4x4 10% discount)

So $257 for all parts for 1 ton disc brakes for a rear axle. You may need a Master Cylinder upgrade depending on your vehicle. I got a 2004 Dodge Ram 3500MC w/big reservoir for my TJ for $109.99 at NAPA. For our YJ I got a 1968 Corvette MC (yes it was a bolt up!) for $16.99 at NAPA. You may need a metering valve if your peddal stroke is to long but they are cheap too.

Like everyone was saying the $900 kit os way tooooo much. I've done a 14Bolt rear and a Dana 60 rear just this winter for the Jeeps and it was a bolt up affair. I did make some tabs to hold the rubber lines in place for the hard line connection, but very sinple fab. It was $55 for the braided 12" caliper lines for a pair if you want to upgrade from rubber. I have also done this on 3 different 8.8 swaps.... supper easy.

Here is a pic of the 14b for a TJ I did (during mock up)..


Here's the last 8.8 for a TJ I did..


The 8.8 parts were dang near same price as the big stuff!!!
BTW- replace all the hub/axle bearings and seals while your at it, it's not expensive either.

The big 4 wheel disc brakes ROCK! especially with big heavier tires!

[BIGRAM]

Yeah, I figured you was pulling my chain.


Thanks for the parts list, that will make it much easier. I'll let you know how the process goes. I guess I'll have to paint mine all pretty as well.
