Well looks like the seals in my front brake caliper on the 77 have shit themselves as there is fluid on the disc. Having not done these before and its the brakes which is critical is there any hints to rebuilding these to get them right?

I rebuilt my banana brake this way:
-bolts off with 1/2" or 3/8" wrench/socket. It must have 12 tooths/corners (I can't remember the correct name)
-piston off with compressed air. Put the piston side down so it don't fly to your head.
-there is one seal/O-ring. Clean everything and put new O-ring. Cover it with fresh brake fluid. Put also new dust cover.
-Then just carefully press in the cleaned piston and your almost done. Just put the two sides of the banana together.

If the piston is pitted/rusted you must clean it or replace it.

Thanks JPP. If I dont have access to the compressor any other way to safely get the piston out?

Sure leave the brake line hooked up and use the pressure from the master cylinder to push the piston out by pumping the lever.

make sure everything is very clean when you do your assy. if the piston is rough sand it smooth,dont worry about every little imperfection as the piston never touches the bore. as with any hyd. part cleanclean clean. thats the key. good luck
