Rear disc brake ???

On my street rod I have a ford 9" rear end with early 80s cadillac [GM] manual disc brake calipers.Its been fine for three years, now I've just changed the rear gears , which meant pulling the axles. I unbolted the calipers and wired them up and did not take off the brake line. When I re assembled everything and tried the brake pedal it went almost to the floor. Its still on jack stands so I don't know what the stopping power will be, but the pedal is much lower than I want it. Any Ideas? Thanks , Joe K

Did you swap rotors one side to the other or have your rotors turned? Those pads are self-adjusted by actuating the emergency brake. Throw several emergency brake actuations/deactuations at it and see if your pedal comes up.

Hope this helps...

Thanks Cam, I tried applying the emergency brake a few times, without any results. Not being familiar with how the adjuster works is it possible that mine are froze-up,and how should I go about freeing them up. Thanks Joe k

Classicperform.com
has instructions for this on their website.
There is a typo in there that actually gives instructions for the other caliper.
(if it has not been updated)

The idea is to adjust the pads as close as possible to the rotor and still get the E-brake arm on in the right orientation (arm should just barely touch rear stop)

Kind a pain in the hiney to figure out the first time, but once you have it, piece of cake.

Also these calipers are bled easier off the mount, I know on my application the bleeder is not at the top when mounted.

Well today I tried to adjust the rear calipers,as instructed on the CPP web site. I felt comfortable in doing it and was hoping for good results, the emergency brakes worked fine, but I had my helper push on the pedal and I was still able to turn the rear rotors with a short pry bar.The fronts were locked up tight. I have'nt driven the car since last fall,and every thing was fine when I parked it, could the problem be with the master cylinder? Any thoughts or ideas. THANKS Joe K
