Cadillac rear discs Setup help

[smhigh]

I've been trying to get my read discs to work

It's a cadillac rear caliper with ratcheting parking brake

I've pumped the e brake over and over and have tried to get the adjustment close by turning the caliper piston out with the special caliper tool

No luck so far

Any one have the trick to getting these to work w/o going to a wilwood setup with drum e brake?

Go to MPBRAKES.COM They have a tech sheet on how to adjust. Basically you install and pump e brake arm till pads are extended.

Be careful it is easy to screw up the adjuster.

I had a customers car in last year with those that rear set up, another shop installed, never could get rear brakes, then i got to fit it.

I took them off, and did a LS1 rear set up.


theres another shop a few miles from me, that had a car in there shop with the same problem.

I've Had the Caddy setup on the Heap for 5+ years now-Works good.
When I got he calipers from the junk yard the pads were shot.
I used the square lookin tool and screwed the piston in only enough to get new pads in,the adjustment mechanisim works in very small increments so if you screwed the piston in all the way it will take a while to adjust out.
Also I belive you should only turn the piston one way(not out to take up slack)not sure on that though.
The Caddy setup works but can be problematic to be honest

The Caddy calipers adjust with the e-brake levers.

Install the rotors and calipers. It helps to use some lugnuts to hold the rotor snugly on the axle. Remove the e-brake levers and the cable brackets. Use a wrench to rotate the e-brake shaft until the pads are firmly against the rotors. Put the e-brake arm onto its hex on the shaft. If the arm is within 1/4" of its return stop with the pads tight against the rotor, the caliper is properly adjusted and you can install the nut and cable bracket.

It the arm is not close enough to its stop, rotate the shaft the opposite of its normal rotation and then back to tighten the pads again. It should ratchet to a different stopping place. I use the nut hand tightened onto a short wrench to keep the shaft from withdrawing into the caliper. It may take several tries, but keep ratcheting it and reinstalling the arm until the arm is within 1/4" of its stop with the pads tight on the rotor. Use the e-brake frequently to keep the caliper adjusted as the pads wear.

I have the cadillac calipers on my ford 9". Didnt have any issues at all. Just curious, what is the problem? Brakes not working, parking brake not working, pads dragging??

I just installed them as I would any rear disc brakes, honda, toyota, fiat, any of them. I seat the pistons in as far as they will go, set the pads on, bolt the caliper up and take up the gap with the E-brake. Usually one or two cycles and they are seated. The calipers dont have much volume for fluid, one pump with the E-brake usually does it.

If you have a guy that can pull the E-brake while you can be under the car to see if the lever is moving then that would be helpful.

If you see the lever on the caliper move, even the slightest then Im thinking the system isnt bled correctly.

Are the brakes working under normal brake pedal use?? Check that. Sounds like a bleeding issue.. JR

Have this setup on my '71 Chevelle......did what red67camaro did. Still took about 2 weeks to settle in. After that brakes work well but, be sure to set your e-brake EVERY TIME you shut down to get good contact on the rear.

Looking now to switch out to LS1 rears. Can't leave well enough alone
