This might be old to many of you, but here goes. I have several questions about rebuilding the rear calipers on my 73 3.0CS with vented rotors.
1. I got rebuild kits FTE RKS4202. Perhaps @Denis1967 has answered the question about the piston seal taking a set, but the new seals look to have a very square profile, making it impossible to get the piston back in by hand, even after liberal coating with brake fluid. The old seal appearS to be tapered toward the outer edge. I put one of the old ones back in and was able to pop the piston in by hand. It is normal to require considerable effort of a C clamp or harbor press to get them in with new seals?
2. Where does one find ATE paste that is compatible with brake fluid?
3.The "bible" indicates that the pistons are to be repositioned at a particular angle, 20 degrees, using (of course) a special piston gauge. What function does that cutout and the angle of insertion
serve???
4. I split the piston halves, and have new O-ring seals. Referring once again to the bible, it cautions to not reuse the "expansion" bolts. Too late. Seems like high temp Loctite should work using original bolts and nuts, right?
Thanks for the help. I f you need advice about a Volvo 1800, I'm your guy.
