1983 brakes

Postby dsimmonds53 » Tue Aug 31, 2010 7:26 am



I'm restoring an '83 Interstate and the unified brake system is toast.
I'v taken apart the front right caliper, the rear caliper, and the master cylinder. I can rebuild the master, but the rear caliper is totally gone. The last owner cross threaded the bleeder and it's frozen solid. My question is this:
Can an '84 GL1200 rear caliper work, and can 1982 front calipers work.
They look identical, but looks can be decieving.

Thanks

I am not sure..but if they mount up and fit the rotors then sure..easy to check w/o hooking up all the lines and everything..just slap them on and see...but the bleeder will come out..and you may be able to retap..not a hard thing to do worth a try. Soak in blaster then a littel heat on the caliper at the bleeder and 8mm wrench with a breaker bar on it..and she'll move..nothign to loose anyway.
HAD LOTS OF GOLDWING 75-83

I've heard of people rescuing a caliper with a seized bleeder just the way you say. Worth a try, then the caliper can be rebuilt.

Measure the diameter of the pistons. On the unified brakes, the calipers up front look identical but are not. One has the same size pistons as the rear and if I remember correctly, will interchange with the rear.

Thanks
The pistons in the rear are larger than the pistons in the front right. I haven't removed the front left as yet. It's the only brake that works.
I plan on replacing the fronts with a set of 1982 calipers. I bought an '84 rear caliper and have my fingers crossed it will work.
I matched a picture with my caliper, and the only difference I see is the lack of a splash guard on the '84. all the bolt holes appear to line up.
WISH ME LUCK!.

As for that frozen bleeder, go to the autoparts store and get a can of Freezit or Freezoff. Have a small hammer and a drift handy. Not a Pointed center punch but a squared off drift. Give that bleeder one good long squirt. Put the straw straight down inside the bleeder and be careful that it doesn't shoot back onto you. Now you can use hammer again on a combo wrench or small breaker/socket.
