Looked in my notebook, it was five years ago and about 100000 km. Of course they only pack, I think.

I bought and installed on my 90
- Front stainless pistons (46mm) from Island 4x4 c/w seals AEU2539G as a kit - Rear stainless pistons (think 41mm) from LOF as a kit (LOF did not have front and rears in stock at the time ) I found no difference in the quality of those from LOF and set bought from Island 4x4 I also bought spare set of seals for both front and back calipers - luckily I did cause on installing one of the seals I did ever so slightly deform the seal retaining rings make sure buy some hose clamps - small ones - if you have not got any All been installed approx 2 years with no issues what so ever. The original pistons they replaced were generally not too bad, I had one on the rear and one on the front which I feel would have damaged the seals when pushed back in so glad I did change them at 5 years old (I live by the sea) |

I concur very handy to have - used exactly the same and very useful for seating the seal retaining rings evenly |

Sorry I missed this. But brilliant tool  I was rather taken by Britannica's caliper tool as well.
A New Years present I think...  |

Excellent post. Many thanks This will now be a New Year project.
Did you split the callipers or keep them in one piece? |

Keep in one piece. Just enough room to do one piston at a time > 110 XS Double Cab

There are many who say that it is unwise ever to split the calipers, although it is hard to see why this should be. It is certainly not easy to find the correct replacement gallery seals if you split them.
It isn't really necessary to split them. |

There was a time…. the only time I’ve split a caliper was on an original Mini, fitting Cooper ‘S’ brake discs and callipers… but it was a Mini, and it was 1989..
At that point the kit came with the pistons, piston seals/retainers, and the gallery seals. I’ll be doing a complete replacement/rebuild front axle on the Defender next year some time so I’m just following this thread to know more about the caliper options. I’d heard of Big Red previously and thought they’d be worth a look.

Merry Christmas one and all. As part of ongoing repairs/upgrades, I’ve got the brakes to do. I’ve bought new braided lines, new pads, will be getting new discs etc. The piston upgrade is something I’m also keen to do, so this is all very useful info. But can I ask, just to know, is this modification just about future-proofing the brakes (rust prevention, wear and tear etc) or does it also actually improve braking? Monsieur Le Grenadier

More so future proof, my defender was 6 years old when I changed mine and I live by the sea
They would not have lasted another year as two of the pistons were showing significant rusting that would damage pistons seals when pushed in with new pads. It is worth doing but get some spare seal kit as you will buckle at least 1 dust/retaining ring (well i did  ) |
