LD 19 questions

[Jeff Smith]

Once again being a glutton for punishment, I decided to rebuild all 4 calipers. I found that 2 had 2 cross feed seals and 2 had only one hole. Is one better then the other? Should I mount them the same on the same axle or does it not matter?. they were not mounted the same originally. Also one piston had a much thinner wall then the others, any reason?
After cleaning the pistons and polishing with 400 grit, still had some pits, should these be replaced? Pits arent deep or very large.
Finally, any pros or cons to using the outer seals or not?

TIA
John

I'd guess the later parts are the ones with the two crosses and also have two proper bleeders. I'd put the cross over on the bottom when refitting it if not already that way. Sort of self bleeding.

If the outer chrome is not broken down to the copper base coat and the pits not big chunks, and they didn't leak before you'll be fine using them.

The pistons varied a bit from what I've found too. No reason I can see for it, but for alternate manufacture. Most of the new ones are the thicker variety.

Fitting outer seals is fine, just takes time to do it. The rings are best seated with a proper size round slug or maybe a socket if you're lucky. You get one shot at seating it in place. When it's bent you're history.

Forget the outer seal - it's original function was to keep out road dirt for 100,000+ miles.
