Several years ago I had a client that was really into mud racing, he had a ranger at the time that was built with a 9 inch rear end that he had swapped disc brakes onto. He told me where they came from but that was a while back and I can't remember what donor vehicle he used or exactly what he did. I do remember that it had drums and he changed them to discs, he didn't swap in a disc equipped axle. Has anybody here done this or know exactly what to do? I hate drums but don't want to put another $700-900 in a truck that won't spend all of it's time on the road. Thanks.

 

If it was the car lug pattern , he probably used the 95 ford explorer. We had a curry 9 inch and the directions it said to use the above suv for replacement discs.
We did a direct disc conversion on my cousins 69 fastback mustang.

 

Older Lincoln Versailles had disc rear..

 

What "above suv"?

 

When I was typing it, the 95 ford explorer type was the sentence above. When it laid out to display, the sentences were on the same line. Sorry.

 

95 explorer...

 

The original poster said his friends ford ranger had rear disc brakes on it. I am assuming he is speaking of the small truck which has the car lug pattern. The 95 ford explorer rear discs will mount onto the car axle. If I remember correctly, my uncle had to make a spacer like a washer to go between the disc and axle. My cousin has been driving his 69 mustang like this for a few years with no problems.

 

I was on ebay the other day and I saw a conversion kit for like $600 and it said it used calipers and rotors from like an 80s monte carlo or something like that

 

There are several instances where front car calipers have been adapted to the rear for rear disc brakes. This works fine except you have no parking brake.

 

Ok so I need the rear brakes from a 95 explorer but how can I get them to fit on my 9" truck axle without having the small car bolt pattern?

 

What year truck are you trying to convert?

 

84 4x4 with 9" rear

 

If it was a 2wd, you may be able to use the 80 or 81 f-100 that came with the 5x4.5 car pattern. Four wheel drive I really do not know.

 

ive heard of people puttin posi axles wit discs off of mustangs but they would still have the small lug pattern and have to get 2 sets of wheels

 

Is it just the lug pattern? You can send the discs out to be redrilled, and the center hub may have to be machined a little bigger (or machine the hub on the axle).Summit has a few kits rnging from $375 to $620.
