Finally did the rear disc brake conversion, I'm very happy with it.
Definately worth doing.

 

Looks good. What steps and parts did you use?

 

You are definitely going to like it, best move I ever made...Mark

 

-used weld on brackets
-1976 Caddilac Eldorado calipers with e brake and braided lines
-80's chev 4X4 rotors
-new e brake cables

Fairly easy actually, take the drum and hub off then press out the studs to separate drum from hub, unbolt the old backing plate.

-install rotor onto hub and press in the studs.
(might have to oversize the stud hole a little on the rotor)

-put the hub and rotor on the axle

-install the pads into the caliper and bolt the caliper onto the new bracket.

-get a grease gun hose and put on a fitting to connect to your compressed
air source, the other end of the greasegun hose will screw into the caliper.

-put the caliper on the rotor and position it where you want it, hook up
the compressed air, the caliper will engage the rotor and now your bracket will be lined up on the axle tube.

-tack weld the bracket.

-remove the caliper and rotor/hub, weld on your bracket.
( I brought in a pro welder for this job )

-clean things up, a little spray paint, then put your hub/rotor back on

-Install the caliper

- I used new Dodge e brake cables, found out that they will adapt easier if
I put them on backwards (front to back)

- The rest is regular brake line and bleeding stuff.

 

Cool! Well, I do not even have a welder, nor do I know how to weld.

Is there a bolt on set up? I do have a 20 ton arbor press, so pressing stuff is not an issue.

 

Is the bracket welded to the axle tube, or the brake back plate mounting flange?

 

Where did you find the calipers?

The bracket is welded to the tube, backing plate flange no longer used.

 

Thanks for the links. Discs brakes and hydroboost are hopefully in my near future

 

any specific p/n on rotors

 

on the brackets- what tube diameter do I need? 3.5 inch


M

 

I think it was 3.25"

 

I used early 80's Chev/GMC 4X4 2500 pickup 12" rotor.

You will have to enlarge the stud holes in the rotor slightly
so your wheel studs will press in correctly.

 

the egr kit I used bolted on and used the '80's f250 rotors, im not partial to the cad caliper, the ebrake adjuster eventually leaks, every couple pad changes, I replace calipers too. im researching the '90's ford e250 d70 rears with the early version of internal ebrake shoes, much more dependable, and caliper will retract without using tool to spin down piston. ive got 200k on mine, its a pita when your spinning piston down, and caliper starts leaking, and caliper takes a couple days to source, just my 2 sense.
