Have you "split" the calipers in half, or just trying to get the seals in whilst the caliper is whole?
I recently rebuilt the ones on the front of my 110, and it's a whole lot easier to have them in half (unbolting them), and yes, they are quite tight, but using that pink coloured rubber grease   makes it a lot easier. |

Thanks Jim, I've split them yes - so they're nice & easy to work with thankfully. It's just getting them to sit flush & tidy thats the problem for me, plus a lack of patience.
I'll give the grease a go to help them in! How did you push them in? Using a clamp or another method? |

i used to use a large socket that sits over the seal to ease them in evenly.
now i dont bother, its cheaper in time to buy a complete caliper and do it that way. Cheers James 110 XS Utility 130 Puma Station wagon/camper (in the making) 90 Puma Hardtop |

As what James says, a large socket that fits over the piston will push that dirt seal in.
As for the pistons themselves, if there's enough lube and they're dead straight, you can push them in by hand, but if they tilt a little bit then they usually jam in and need wiggling to pull out. a wooden hammer handle is handy to stick into the hollow bit to wiggle. |

I also nowadays tend to replace the complete caliper.
Those seals are complete s*ds to fit, especially if you haven't split the caliper. Incidentally if you have split the caliper have you been able to source replacement "O" rings for the seal between the halves? This can be difficult. |

The socet trick worked a treat - thanks guys!
Re. the little 'O' ring seals when the calipers were split, they looked in good order so I kept them in - I've kept an eye for leakage but so far so good! In future I'll go with new calipers |

Yep, another who bought new calipers (all four
 ),re-fitted with proper silicon grease (IMO,Servisol is the best,bayE,Amazon or Maplins).Every year the caliper/pistons should have been cleaned with brake cleaner and re-greased,lazy ar*ed f*kin fitters  . Pov.spec,ftw. 2006, 110,TD5. |

Aftermarket seal retainer rings are notoriously difficult to get into the calipers. It's common to bend a few.
I used a genuine set last time and all four went in no problem. |

As Retro says use Genuine or Lockheed seal kits. I have learned to fit the seal retainer in a vice using the big washer from the end of a radius arm bush. Leave the piston protruding about 3mm from the caliper, fit the wiper seal and the retainer over the piston, make sure all is square, fit the big washer over the end of the piston and squeeze in the vice. The washer pushes the piston down and then squarely pushes the retainer into it's slot. Right first time
Compare this with a 75% failure rate and hours of frustration trying to fit good Lockheed retainer rings on the bench with a screwdriver
